1.Avoid a straight line between the head and body.If the two are straight lines, they will inevitably feel dull. Therefore, when the front of the body is facing the camera, the head should be slightly left or right, and the photo will look elegant and vivid; likewise, when the eyes of the subject face the camera, turning the body into a certain angle will make the screen look angry and dynamic, and increase the three-dimensional.

2.Avoid parallel arms and legs.No matter whether the person is sitting or standing, do not parallel his or her arms or legs, because this will make people feel stiff and mechanical. A proper practice can be to keep one song or both of them in a certain angle. In this way, both dynamic and changing posture can be created.

3.Try to differentiate the shape curves.For female subjects, it is necessary to show their attractive curves. The common practice is to let a character's leg actually support the whole body's weight, and the other leg is raised a little higher and leaning against the standing leg, and the arm should turn over, to show its narrow side, the chest is bent through the waist, as far as possible to show its towering and plump feeling. At the same time, one hand of a character can be placed on the buttocks to provide the necessary width for the screen

4.Avoid sitting posture.When the person is sitting in a chair, do not let the person sit in the chair as usual. In this way, her thigh will be resting, so that the upper part of her leg is too fat to bulge, making her thigh look dumb. The correct way is to let the body move forward, sit close to the side of the chair, and keep the chest and abdomen, so as to avoid the portrait of the belly.

5.The camera should be far from close.Generally, it is better to take a photo of a person than to take a picture of a person. Because malformed occurs when the lens (especially the short focal length lens) is very close to the recipient. Therefore, you should select a proper focal length for photography and keep the camera at a certain distance from the character. According to the practice, we know that if you use a standard camera to take a person's portrait, the best distance is between 6-8 feet, the chest image is between 8-9 feet, and the camera image is (between 13-22 feet. In addition, place the hands and feet of the person to be photographed. the body helps to avoid malformed situations. Once they are more than 18 inch away from the body, they will become out of proportion and the hands and feet will become too large or too small.

6.Good posture.The recipient's hand has a relatively small proportion in the screen. However, improper placement will damage the overall beauty of the screen. When shooting, pay attention to the completeness of the hand, and do not make it deformed, broken, and incomplete. For example, when you put your hand on your cross waist or in your pocket, expose some fingers to avoid interruption.

I,Select a photo of the person taking the background based on the subject stated in the photo sequence. The photographer usually has a very clear topic. Due to the different themes, when selecting the background, the photographer should make reasonable choices based on the specific circumstances. For example, to show the professional characteristics of the person to be photographed, we can take the work scene as the background and use natural light shooting at the scene to create a normal atmosphere, the environment is an important part of the screen. It sets off people in the environment and uses the environment to remind people of their inner world.

If the photo reflects the appearance and temperament of a person, the background should be concise and simple. In this way, the subject can be enhanced to a great extent, make the character image clear and vivid. In order to portray the character's personality and artistic achievements, the photographer chooses an abstract painting background, which highlights the character image and is unforgettable.

II,Selecting different aperture based on the background content once the background content is determined, the method used to express the background becomes a key issue. The specific method used to express the background depends on the background content. if the background is the whole, an organic and important part of the screen, it can convey a lot of information that helps the audience understand the person being photographed, so that the small aperture should be adopted to make the details of the background quite clear. If the background is only used to appear in the screen as an audio and video component different from the main object, you can use the aperture amplification method to blur the image.

III,There is no rule to determine the optimal proportion of the background in the image, but some principles can be referenced. If you take an environmental portrait that shows the person's career, the background may be larger. You can take travel photos of the person as long as it is not as big as the guest's land acquisition, when there are scenic spots and monuments on the screen, the background can also be used as much as possible to avoid incomplete scenery. In addition, we recommend that you take more pictures of the background to avoid a sense of promotion. In contrast, you should take less pictures of your chest and Avatar, so that the audience can focus more on the subject.

IV,Avoid some bad backgrounds. Good backgrounds can help you set off and beautify the pictures. Poor backgrounds may affect the appearance of pictures. In photography, the following scenes are not suitable for the background:

1. The scenery is not messy and complex.
2. A colorful scene that takes the lead.
3. A cold scene (because when it is reflected to the face of the subject, it will make the character look abnormal ).
4. scenes with sharp contrast.

Taking photos on a tour is a meaningful and interesting activity that people love. To take travel photos, you must first understand the basic features of travel photography. What are the characteristics of travel photography? Tourism photography is mainly characterized by focusing on people and views and the purpose of tourism photography. It mainly records what tourists see, hear, learn, and feel during their tours. Every time people visit a scenic site or site of historic sites, they always want to take a photo and place themselves in the beauty of nature and bring them back as a permanent souvenir. Tourism is a distinctive feature that makes travel photography a photography category that focuses on both scenes and characters, between character photography and landscape photography. It requires both human and landscape perspectives. According to travel photography, which requires both vivid and natural characters and strong aesthetic and characteristic characteristics of the scenes, when taking travel photos, on the one hand, we should pay attention to choosing beautiful scenery with local characteristics as the background, and at the same time, we must take into account the performance of the main figures, and strive to make the two perfect and harmonious combination, receive the artistic effect of scenario blending and matching each other.

Combination of GRASP and swing 

Pendulum is the most used form of travel photography. A family trip or group of friends, always arranged in one line or several lines. Most of the commemorative photos of "here for a tour" are the first to select the background scenes and then arrange the characters for shooting at appropriate positions. Although this kind of "insurance" photo taken with an easy-to-use method is understandable and sometimes even necessary, compared to those in the process of people moving, the pictures captured during the conversation, however, seem monotonous and dull. Tourism is a type of interesting sightseeing and entertainment activity. Tourism photography is a loyal record of tourism activities. Therefore, whether the pictures are vivid and natural, and whether there is a strong sense of life is often the key to the success or failure of a travel photo. In tourism photography, in addition to taking commemorative photos of "One tour here", you may also wish to adopt the capturing method, shooting without interference, for example, road, cooking, camp, picnic, bonfire, entertainment, hiking, water-related, conversation, diary, swimming, games, and evening parties, and help each other and other unique and Vivid scenes of travel life, reflecting a variety of travel life. In fact, although technically defective, a picture is more popular than a picture with no major technical faults but too rigid. Even after several years, this kind of photo can help you recall the voice and smile of people and arouse your memories of the wonderful travel life of the past.

The third characteristic of tourism photography is that a wide range of tourism is a comprehensive activity with strong knowledge, and the footprints of tourists are all-encompassing. During the trip, tourists have the opportunity to get in touch with a variety of things and capture a variety of lenses. As long as you have a wide range of interests and pay more attention on the trip, you may take various valuable photos. It is not just a commemorative photo of this tour, but a documentary of travel life with the basic content of eating, living, and behavior that is the subject and content of travel photography, rare animals, flowers and plants, beautiful natural scenery, and special customs can all be taken into your camera. If you are interested, you can take photos of scientific knowledge, such as geology, geographical landform, rock, volcano, and fault; community and growth of vegetation, internal structure, regional characteristics, and shapes and specimens of various plants; types, groups, living habits, appearance, and ecological environment of animals, as well as climate features, archaeological discoveries, architectural structures, and singular phenomena, these will greatly broaden your horizons, increase your knowledge, and bring you great pleasure.

Of course, there are many other characteristics of travel photography, which are not limited to the above points. However, I think that in terms of artistic performance, we pay equal attention to the combination of human views and shooting techniques, as well as the extensiveness of the materials, tourism photography is the most fundamental and different from other photography categories.

As a category of photography, does landscape photography have the problem of capturing images? The answer is yes. The amazing, unexpected light, shadows, shapes, and colors of landscape photography have made the viewer highly appreciated while advocating nature. Excellent landscape photography works all contain the accumulation of artistic thoughts by photographers for many years, the innovation of shooting technology, the rich scientific knowledge, and the spirit of hard-working and hard-working. They are also the results captured by photographers.

Landscape photography has its own characteristics. Landscape photography should be good at grasping the "Timing". Generally, after selecting a scene on the ground (including the water surface and mountains), the photographer will depend on the sky, that is, the effect produced after meteorological changes, to render the image. This requires photographers to learn and understand meteorological knowledge, master the laws of weather changes, and select the weather conditions that match the creative intent for shooting.

Sunny, sunny, and clear scenery. At this time, the picture tends to be normal, but sometimes it can also be pleasing to the eye. To achieve the desired light and shade effect, it is best to take a photo in special weather conditions. Such as the ever-changing cloud, fog, rain, wind, Rainbow and lightning. Meteorological changes are not subject to the subjective desires of photographers. You must understand the weather and geographical conditions in the area, be sure to know your knowledge, and be patient and wait for the shooting time.

For example, we went to the Great Wall to create a project. Beijing is not far from the Great Wall. meteorological changes in the same region should be easy to grasp. However, if you do not know or know the weather conditions in advance, you may encounter "good weather" because you are not prepared for it, promotion shooting. As a result, energy and financial resources are wasted.

The timing that nature gives us has its regularity and particularity. For example, Mr. Yuan Yiping shot the "Oriental red", with colorful clouds on the screen, the sun rising from the east. The Tiananmen city is magnificent and magnificent, with a reasonable picture and a strong color impact, shows the prosperous and brilliant Artistic Conception of the socialist motherland. As we all know, the sunrise orientation varies by season, latitude, and geographical environment. Shooting is only applicable when the angle between the sunrise position, the ground scene (Tiananmen Square), and the photographer are in line with the structural requirements. This time of the year has a certain period, which is its regularity.

After selecting the orientation of the sunrise, you need to select the appropriate clouds. This requires waiting. One year is not enough to wait for the next year until the expected scenes appear. This is why Mr. Yuan Yiping took 10 years before and after shooting successfully. This is its particularity.

It can be seen that landscape photography is very important to grasp the regularity and particularity of shooting timing. Landscape photography captured the precious "time" and the shooting work was half done.

Second, landscape photography's requirements for "instant.The "decisive moment" of French photography master breson also exists in the landscape photography practice, which also reflects the soul of the work.

For example, shooting videos in the cloud and sea. The cloud sea is not static and changes at any time as it is affected by the airflow. When the cloud sea is relatively stable, although some good photos can be taken, but the real fantasy, spectacular, and magnificent scenes, the cloud sea is still triggered by the effect of the wind, the moment of change. At this time, almost no negatives of the same image were found. If you press the shutter too early or too late, you may lose the best instant. At this time, the capture is very important, which is the key to the success of the work.

In this case, you are engaged in watching in the preset scenario. A good cloud shape is not in it, or the location is not suitable. When you move the camera to follow it, the prospects are not very good. At this time, if you are not experienced enough to capture images in such an environment, you will lose sight of this. The so-called "east, west, and West" cannot catch the "decisive moment" of the scene, leading to a loss of shooting. This requires the photographer to "be confident", be skillful in using equipment, be accurate in measuring light, be agile in action, and immediately solidify the beautiful moments that nature gives you on the negative film.

This photo of the author (see the topic) was taken in Wuling mountains in Xinglong, Hebei Province. At that time, when the rain was getting fine, the clouds were surging between the peaks, and the peaks were quite charming. Based on the characteristics of the changes in the cloud, the author looks for pictures with strong rhythm. In the composition, we try our best to take care of the ratio of the mountain to the cloud, and use different focal lengths to properly show the relationship between the cloud and the mountain, thus achieving a better artistic conception. The image of this photo is captured by the foreground mountain while following the clouds.

Third, the impact of equipment in landscape photography on capturing.Landscape photography also has its own particularity in the use of equipment. It is precisely this particularity that makes landscape photography in the capture process, but also subject to equipment constraints. First, landscape photography has strict image quality requirements. Generally, films with lower sensitivity than iso100 are used to achieve the effect of Thin Film particles, delicate shadow and colorful colors. Second, in most shooting conditions, a small aperture is required to achieve a large depth of field range. In this combination of exposures, the shutter time is extended accordingly, making it impossible to take a shot with a hand-held camera. A solid tripod must be used to ensure image clarity. In this way, compared with other photography categories using high-sensitivity films, high-speed lenses, and handheld cameras, there is no advantage in capturing videos.

To overcome the above restrictions on landscape photography, efforts should be made to use the equipment skillfully. Cameras, tripod, accessories, and other equipment must be used freely. If necessary, you must exercise the equipment in advance. The equipment in the photo bag should also be neatly, orderly, and easy to use. Shooting outside. The departure time should be earlier or later. Enough time to use the equipment.

The author's shooting experience is very informative. It was on the dam and planned to arrive at the shooting point before sunrise. Unfortunately, the car broke down halfway and had to walk, which delayed the time. Suddenly there was a rare red light in the sky, and the surrounding mountains were red, very spectacular. I took out my camera in a hurry and opened the tripod to prepare for shooting. However, just after I mounted the camera on the tripod, the red light in the sky has weakened, and the red light has quickly disappeared from red to pink, this rare moment was not captured. In retrospect, I always feel sorry. It can be seen that landscape photographers should pay attention to the influence of equipment on capturing. Overcome its adverse effects and constraints by using various feasible methods and methods, and change the unfavorable factors into favorable factors. It can be said that equipment is the "hardware" in landscape photography, and skillful and correct use of these "hardware" is a guarantee for the success of capturing beautiful moments.

We often admire the fleeting and unpredictable light and shadows. It is precisely the skill that photographers grasp in an instant that makes landscape photography full of magical charm and presents scenery photography.

I. Preparation: select a proper location, a proper time, and use the appropriate equipment to take the sunrise and sunset.Everyone knows that the sun rises and falls in the east, and passes through the sky from left to right. When you think about taking effect in advance, for example, you want to use a rock that needs to come out of the ground as a foreground, but the sun does not just fall behind it; the sun will move to the right and may miss this rock, if your goal is to take a picture when the sun falls onto these rocks, you must first move to the left to take the desired picture.

2. Appropriate season: the best season for shooting sunrise and sunset is spring and autumn.These two seasons are later than the sunrise in summer, and the sunset is early, which is advantageous for shooting. There are many clouds in spring and autumn, which can increase the shooting effect.

3. Cloud: the cloud is a natural reflective object during shooting. It can spread the red light of the sun and change the same works.Clouds can also be used as the main theme for shooting. But pay attention to the situation when the cloud covers the sunset; the light will be shot everywhere after the cloud, so that the photo is extremely attractive. When the kernel is too difficult to run, the cloud will see a bright and bright scene, which is also very suitable for shooting. Note that when the sun gradually appears in the middle of the bright side, capture the video.

Iv. Reflection: the reflection on the water surface adds color to the pictures of the sunrise and sunset. The calm sea or lake can reflect the scenery in the sky.Presents the same image as in the mirror, and the breeze blowing over the water will always disturb this reflection. Leave a brighter light on the water and draw a margin from the horizon to the foreground of the screen. When the sun gradually falls, this light path will extend to your eyes.

5. Yi Xian. Direct exposure reading to the sun is always inaccurate. This will lead to only the sun on the screen, but the remaining part is not exposed.There are two ways to help you determine the appropriate exposure readings. First, let the sun be in three different positions in the viewfinder, and then take the average values of the three exposure readings. Another method is to directly use the exposure readings when shooting above your head. When shooting the sunrise and sunset, different exposures will produce different shooting effects. Therefore, you can choose to review the shot of the impression readings at the top and bottom of each shot at a time (add one file and narrow down one person ).

6. Lens: You can use any camera to take a sunset. However, if the sun itself is the subject of the screen, use a long focal length as much as possible.On the standard 35mm screen, the sun is only 1/100 of the focal length. For a standard lens of 50mm, the sun is only 0.5mm, with a lens of 200mm. The sun is 2mm, with a lens of 400mm, and the sun is 4mm. Once the sun begins to fall, the brightness of the light will be significantly reduced, and you will soon need to use a slow speed, holding a telephoto with your hands, very unstable. Therefore, when shooting the sun, you need to prepare a tripod.

VII. aperture; when sunset is the topic of the work, you should pay more attention to controlling the aperture size.The smaller the aperture, the better the effect.

8. Glare: directly shooting the sun will produce face light in the camera, which will cause serious imbalance in the image contrast, at the same time, the incident light is reflected to the film by the lens surface to form a spot line.High-quality masks help to restrict glare while using a minimum aperture to reduce these spots. Contrast imbalance should be avoided, but the facular lines caused by lens surface reflection can be used as part of the composition of the work. The use of a single-lens reflective camera has this optical shift effect, but other cameras are prone to errors and problems.

9. Color arrangement: when the sun gradually falls in the air, the color temperature decreases to form a warm tone.Before the sun was red, it began to show dark yellow, orange, and red on the film. This effect will increase the color of the screen. However, there are very few photographers who can think of changing the tone which is actually wrong. For photographers who want to take real scenes, the 82a light blue filter can remove the warm and warm tones from the sunrise and sunset photos.

10. Protect your eyes:When the sun approaches the horizon, it is generally safe to observe through the viewfinder. The higher the sun is in the air, the more dangerous it is to directly observe the sun, especially with a long distance lens. For safety, you can stick a piece of running or black film (a 35mm-long small film is ideal) to the viewfinder, so that you can observe the sun and determine the best picture.

The breadth and abundance of shadows. 

With the increasing popularity of digital technology, digital cameras (DC) are no longer rare objects. In today's digital era, new requirements have been raised for people based on their original shooting techniques. Many novice users have reported that the pictures taken by digital cameras are dimmed, lack of energy, noise, light depth of field (especially in macro mode), color, and so on. However, photography is a bridge between the mind and the light. It is not easy to master traditional shooting techniques. Next, let me give you a brief description of what digital cameras need to pay attention to during shooting, as well as some before and after shooting.

1. Browse Manual

Many users do not like thick and tedious product manuals. They generally like to explore the product after purchasing a digital camera. Of course, there will be some surprises during the exploration process, but it will take a lot of time, and you cannot learn the features of your products in the shortest time; if you have read the instructions, you can avoid some errors. Therefore, when you are new, you should first look at the instructions carefully compiled by the manufacturer to familiarize yourself with the basic menu and functions of digital cameras. In the future, you can flip it over when you are not clear about it.

2. Reasonably choose the image format

We all know that the quality of digital photos is related to pixels (resolution). The higher the pixel, the better the image quality. According to the actual situation, a digital camera of 2 million pixels has the same digital image acquisition capability as a scanner of 1200 dpi, A 6 million pixel digital camera can be considered the same as a 2400 DPI scanner. If you only use a general platform scanner to digitize photos, a digital camera only needs 2 million ~ 3 million pixels can easily beat a 35-mm camera. However, if 4 "x 6" is output, about A6 size, the use of 200-3 million Xiangsu can meet the needs of ordinary people. However, if it is only used for a computer 72 dpi display, the requirement is lower. The resolution is 1024x768, which is about 0.8 million pixels. Any 2 million-Level DC can be used easily. Because the storage space of digital cameras is limited, we need to adapt to local conditions and choose a reasonable resolution, such as: Only for PC, for my Sony DSC-s75 general use 1280x960; such as for printing, generally, 1600x1200 is used. Of course, 2048x1536 is used when taking photos of life. In the case of low requirements, the compression standard also uses standard, which can save more than half of the images than the fine compression standard!

3. Architecture and thinking

Users who have a certain understanding of photography can clearly understand the importance of accurate composition. For example, if a close-up is not taken, the subject should generally be placed at 1/3 of the screen, and the background should be avoided as much as possible, shooting from a special perspective, and capturing the details and personality of the object as much as possible, using the background diagrams of some diagonal lines or curves will make the overall picture more vivid.

In addition, we should be good at observing with two-dimensional eyes. Because photography only has two-dimensional space, it expresses the space sense through the perspective relationship (I .e., the effect of light and shadow is a reference object), different from the three-dimensional human eyes that observe things from two different angles. However, most of the current digital cameras have visual LCD screens, and their field rate is above 90%, with some close to 100%, for example, s75 reaching 99%. You can directly observe whether the sense of space and the sense of distance are sufficient to make timely adjustments. However, the LCD resolution of a general digital camera is relatively low, and the resolution is generally unsatisfactory, but the pen is quite satisfied with s75. Either way, you can't be superstitious about it, because in actual use, we found that the display on the LCD is slightly over-exposed, and the display on the computer's monitor is exactly the same. This is also the reason why some users always make dim pictures.

Moreover, LCD Power Consumption has always been a headache for "color friends". Therefore, many "color friends" are still used to using the optical viewfinder during shooting. Considering that the field rate of the optical viewfinder is only 80%-90%, when shooting close-up, remember that it is an off-axis! Of course, if you want to take a spectacular picture, you have to close your eyes and use the thumb and forefinger of both hands to build a "frame ", think of the current scene as a picture printed in a book or on a wall ......

4. Do not be superstitious about the automatic mode of DC.

First, the biggest difference from traditional cameras is that DC has a white balance. This is a bit similar to the color temperature in traditional photography. It is precisely because beginners do not pay attention to this white balance that it will produce partial colors. DC generally provides four modes: automatic, indoor, outdoor, and manual. Beginners always rely on auto, and the pictures they can usually take are in a certain color, as long as we pay close attention to the LCD window, we can see it. When we have just shot a certain kind of object, this kind of object usually focuses on a certain color. If it is blue, the white balance of DC will be automatically biased towards blue, when shooting other objects again, it will naturally be partial. Although this will be reflected in the LCD, it is generally not noticed by beginners. At the same time, some models are not perfect, such as Sony's DC in indoor mode all have the "Blue syndrome" status quo, so we should try to use manual white balance as much as possible. In addition, we need to pay close attention to the color changes of the LCD. Once we find that the white is not white, we have to re-correct the white. In addition, some digital cameras also have an automatic surrounded White Balance Function to record accurate color information.

Second, aperture and shutter control. We recommend that you use the manual mode if you have a manual image, because the image is usually dimmed in the automatic mode, especially in the window, with more noise. Because in the indoor shooting, DC will automatically increase the ISO value, such as: Sony DSC-F505V in the indoor generally up to 282, and the sensitivity and image quality is inversely proportional to the relationship, that is, the higher the sensitivity, the worse the image quality. This is similar to the characteristics of traditional photosensitive materials, but it is more obvious on digital cameras. Because in traditional photography, we can change the sensitivity of a video by choosing a different sensitivity film or by "increasing the speed", but digital cameras cannot, it can only improve the reaction speed of CCD by improving the sensitivity of CCD and the gain of the circuit, that is, at the cost of filtering performance and resolution indicators. In this way, a signal noise problem will occur, in the end, it leaves traces on the screen, which is very similar to the coarse particles of traditional high-sensitivity films. Therefore, when shooting with a digital camera, if you want to obtain a good imaging quality, you should try to choose a Low Equivalent sensitivity, or directly fix it at the minimum value.

Once again, DC has a macro mode, and the aperture of the digital camera is generally large, up to around f2.0. In automatic mode, the camera program also tends to use a large aperture to shorten the shutter time and prevent vibration. But photography knowledge tells us that the shrinking of the camera lens is generally from the maximum aperture to the left and right of the two levels of shooting the best effect. Especially in the macro mode, such as: Sony DSC-F707 in the flowers, only the middle part of the clear and delicate, surrounded by slight fuzzy. Therefore, we 'd better use the aperture prerequisite or full manual mode, using a smaller aperture to expand the depth of field. If the camera does not have the aperture priority function, you can try to increase the ambient brightness as much as possible so that the camera can automatically select a small aperture or use the flashlight to improve the image quality.

5. Correct light usage and dialog with light

Light is the soul of photography. Therefore, we need to pay attention to the changes in light, not only the intensity of light, but also the direction of light. For example, the sunset turns the sunset into red, symbolizing romance. The dark sky shows a gray and cold color, symbolizing melancholy. the shade of the tree removes a bunch of sunshine, which excludes joy and pleasure ......

Resolution Light Intensity 

Hard dimming is usually triggered by a single light source, such as the sun, spotlight, flashlight, or single light bulb. Under such illumination, the contrast between the subject and the details and texture are highlighted. You can use this light to get the documentary effect. In contrast, diffuse light produces less light. Indirect indoor lighting, outdoor shuyin and overcast weather are all in this situation. Shooting portraits and quiet outdoor scenery in such light conditions are far from ideal.

Light usage 

Different from the light angle, the texture of the subject is reinforced or weakened accordingly, and the shape of the subject is highlighted or diluted. The tone of the photo is pleasant or melancholy, and it may vary with the angle of light. The light projected from the top or back of the camera (usually called the front light) reduces the sensation of the subject because the front light is not conducive to creating highlights and shadows. A better choice is to place the light source on one side, which is the side light with a large angle of about 45 °, so that the shape and details of the subject can be well displayed.

When the light is directed at the camera, the backlight is generated. The shooting object is quite dramatic in the backlight. When taking a portrait, the backlight produces beautiful contour light at the margin of the character's hair. The contrast of high backlight can produce the effect of silhouette.

In traditional photography, a color temperature problem that cannot be ignored or easily grasped no longer exists in digital cameras because digital cameras can be adjusted by white balance, the relationship between the color temperature of the light source and the negative film does not need to be considered. This is a major advantage of digital cameras.

Compared with traditional photosensitive materials, especially new dye-type photosensitive materials, digital cameras have no advantage in the exposure width index, therefore, accurate exposure is still the basic principle for digital cameras to achieve good image quality. In actual use, we found that digital cameras have higher requirements for light and are especially important for indoor shooting. Therefore, we should try our best to use the flashlight when shooting outside the room.

6. Several misunderstandings 

UV filters 

For traditional photographers, UV mirrors are essential. However, because the DC light sensitivity interval is shifted to the long wavelength, it is sensitive to red light and infrared light, but not to blue violet light (especially ultraviolet light. Therefore, adding a UV mirror to a digital camera will not achieve the expected benefits, while a UV mirror with poor optical performance will also have a negative impact on imaging. So, UV is no longer required.

Tripod is yellow yesterday 

Don't think that except for professional photographers or those enthusiastic photographers, a tripod is no secret to digital cameras. To take a clear image, you must hold the camera firmly. Even the slightest jitter may cause blurred images, and we are often helpless with such results, this effect cannot be eliminated through post-production.

Of course, this problem also exists in general film cameras. However, due to the low light sensitivity of digital cameras, a series of circuit processing and shutter delay problems are required, such: the shutter delay of s75 is nearly 0.1 s, which takes longer exposure time than the film camera using the fast film, especially when the light is weak. To stabilize the camera, try to clamp your elbow during shooting and place it to the most stable position of the person-forehead, and gently press the shutter. But the best way is to put the camera on a tripod, or put it on a desk, counter, or other non-moving objects. Especially when taking close-up or macro photography, you can use a tripod to get better shooting results.

Ignore post-processing

Only a few of the digital images taken with a digital camera look perfect. In fact, they are also taken with a normal film camera. Of course, the advantage of digital images is that they can be processed later, but some people will think that this has lost the true meaning of "Fidelity. In fact, it is still on the basis of photography creation, through creative ideas, using a variety of digital technical means, the photographic material optimization or combination, so as to become a magic re-creation of artistic works.

As long as you take advantage of image editing tools, such as Photoshop, you can make the photos that are not outstanding. You can highlight underexposed images, correct color balancing, and cut out the distracting background to cover some small defects (such as the hotspot caused by reflected light ), you can even combine several photos or images (see figure ). Being able to edit photos is one of the main advantages of digital cameras.

7. Value of knowledge in application-practices 

Not necessarily "skilled workers", but "skilled workers" are required, and digital photography is no exception. Therefore, try to take more photos in different light conditions. When shooting, record the camera settings and light conditions used for shooting, and study the results to see which conditions are best set. When taking a photo, a professional photographer always takes a photo of the same image several times. We should also change the shooting angle or exposure time. Most digital cameras have an LCD display.
