How to use digital cameras efficiently

Digital cameras, as an outstanding embodiment of digital technology, are becoming a new favorite of consumer electronic products with their superior quality of use. They have gradually begun to enter ordinary homes, however, it is expensive, so we should be cautious when choosing a digital camera. After all, it is a "luxury" among computer peripherals ", therefore, correct and safe use of digital cameras has become a topic of great interest to all of you. In order to help users who have just begun learning how to use digital cameras get started quickly, I have written some of my experiences and experiences in practical use. I hope this content can help you.

1. shutter speed is a very important parameter for digital cameras. shutter speed varies with different types of digital cameras, therefore, when shooting a scene with a digital camera of a certain type, we must first understand the shutter speed, because the start time of the shutter is taken into account by pressing the shutter, and grasp the release time of the shutter to capture the vivid picture. Generally, the shutter speed of an ordinary digital camera is within 1/1000 seconds, which can basically cope with most daily shooting tasks. Shutter not only to see "fast" but also to see "slow", is the shutter delay, for example, C-2020Z has a maximum of 16 seconds of Fast door, used to take the night scene is enough, however, when the shutter is too long, it will increase the "noise" of digital photos, that is, the photo will contain a complex stripe.

2. images taken by a digital camera generally need to be sent to a computer for processing. Therefore, digital cameras have output interfaces. Generally, digital cameras use Serial Output and almost all have video output interfaces. You can enjoy the pictures you have taken on the TV. If you want to output the image to the TV, we can connect the cable to the video input plug-in of the TV through the camera's video out and adjust the camera to the view mode, the photo can be displayed on the TV rather than the color LCD screen of the camera, but the TV is required to be in the video input mode.

3. Almost all digital cameras now have a small color LCD screen, typically 2 inch or smaller, used to preview or tour the captured images. You can immediately delete an image that has not been taken well. When we use a color LCD screen or a digital camera in "View" mode, once the idle time exceeds 60 seconds, the digital camera will activate its internal color LCD screen protection. Program . The Screen Saver is a continuous flat screen with thumbnail of all existing photos. The pictures will slide around the LCD screen. Press any button on the camera and the screen saver stops immediately.

4. Stability is the first element of Dynamic Photography. To ensure that the captured scenes do not shake in the viewfinder window, we must master the camera's grip posture. Because it takes several seconds for a digital camera to press the shutter to actually complete, it takes longer than a traditional camera. You must note that it is flexible and does not shake. It is best to use both hands to hold the camera, stability is definitely more stable than one hand, or use the items that can be supported by the side or prepare the camera tripod, in any case, is to minimize the shaking of the picture, this is also the most common problem. This shooting method is used in special cases. We recommend that you do not shoot while shooting videos.

5. Do not take out the photo and memory cards when the indicator lights beside the viewfinder are flashing. Otherwise, the photo and memory cards or digital cameras may be damaged. When a digital camera is working, we should also note that, do not rotate the mode disk as you may fail to store photos stored in a digital camera once you change the operating mode. In addition, before shooting scenes, we 'd better ensure sufficient storage space. We should purchase a large-capacity memory card and prepare enough batteries. During the shooting process, use the flashlight and focus for a long time as much as possible, and minimize the number of "video previews", because the preview mode consumes a lot of power, using this mode can greatly shorten the battery time when only battery power is available.

6. When using a digital camera to take a night scene, due to insufficient light, it may take a long time for exposure, but I am afraid to press the shutter for a long time, the camera may shake slightly, which affects the imaging effect. Because many digital cameras do not have a shutter line design, we can use the "tripod" + "selfie" to complete the shooting of night scenes. Based on the actual effect, we found that if you use the "self-timer" method, we 'd better match the camera tripod, so that the possible effect will be better.

7. If you want to view the photos already stored in a digital camera, you can keep the digital camera in "View" mode, a magnifier icon is displayed at the bottom of the menu of the color LCD screen. Once the picture being viewed is completely decompressed, the selection indicator on the menu is visible. Move the selection indicator to the magnifier and press the "finish" button to zoom in the photo and activate the four direction controls on the camera, this allows us to pan the enlarged image around. In addition, when we use the "View" mode to view the photos taken by the camera, we need to wait for a decompression process. Generally, it takes two or three seconds for each photo to be decompressed.

8. When a digital camera is in the shooting status, before taking a scene, we only need to press the "finish" button by hand, the color LCD screen will display the visible scene video image, this provides us with a real-time video framing mechanism. In this way, we can take an ideal picture when it is not convenient to use the framing window.

9. Some digital cameras can adjust the quality of the image to be taken. Generally, there are "good", "good", and "best" levels. As quality settings increase from "Good" to "best", the degree of image compression also decreases. The less the image is compressed, the better the quality, but the more space the image occupies on the photo storage card. Therefore, to optimize the image quality, use the "best" setting,

10. When a photo in the camera is transmitted to a computer, all the photos taken are based on dcpxxxxx. the ext principle is named, in which xxxxxx is the total number of photos taken by the current camera. This number increases continuously until the memory is used up, and then starts counting from the beginning, this number is not cleared because the battery is taken out or all photos are deleted. Therefore, if you need to know the number of shots taken by the current digital camera, you can determine the size based on the number following the DCP on the camera.

11. In order to quickly transfer photos from the camera to the computer, we can first adjust the serial port speed in the camera attribute to the maximum value, and change the serial port communication speed of the computer to the maximum value, to get a fast transmission speed. When transferring a large number of photos, you can use the software attached to the camera. Its name is picture easy software. After the software is installed, a small blue icon is automatically displayed in the Windows system bar. Click the "Download image from camera" option on the icon to display the photo transfer interface, at the same time, remove the check mark in front of the "show thumbnail" option to quickly transfer the photo from the camera to the computer.

12. In order to increase the stability of the image, we should fix the camera as much as possible during shooting. Simply put, after the camera is aligned with the target, we should take a fixed point, do not shoot the camera or scan the camera up or down, set the size of the painting surface and start the video. The fixed lens is used for normal shooting, so you do not need to perform too many zoom operations to avoid affecting the image stability and image changes, that is, using different scene sizes or different angles and positions, to change the size and depth of field of a scene, simply put, it is to take a panoramic view at the back of the camera station. When you want to take a part of the camera, the camera will start a little forward, different positions, such as the side, height, and low position, have different effects and richer pictures. If the site cannot be close, you can also use a zoom lens to adjust the image size you want.

13. correctly and reasonably setting the camera is a prerequisite for efficient use of digital cameras. It is very important to set and check the camera based on the shooting purpose before shooting. It can avoid wasting time and energy during shooting due to improper settings. For example, most digital cameras have two shooting modes: normal and macro. The macro mode is generally used to take a scene of less than 20cm, while the normal mode is to take a scene of more than 20cm. The normal mode is used when taking close-up objects. Either you cannot take photos or the photos are blurred, and the results are certainly not ideal. Therefore, when using a digital camera or a new digital camera that you are not familiar with, You must carefully check its settings.

14. When using a digital camera to take an object, we must pay attention to the shooting distance. If we do not have a good choice of the image distance, we are likely to take a very bad image. This is because, when using a digital camera, the number of pixels is a very important factor in the quality of the image, while long-distance objects are not clear because the number of pixels distributed above them is small, so try to get close to the object you are shooting. For example, when shooting a person, we can enable the color LCD screen to capture the scene, and then let the person fill the whole screen as much as possible before shooting.

15. When shooting the backlight and night scenes, if shooting in fully automated mode, the former must be subject or full-black characters, while the latter must be blurred in the dark ,. To solve the above problems, the best way is to press the backlight correction function key when the backlight is reversed. If this function is not available, switch the fully automatic mode to the manual mode and find the brightness adjustment key to adjust the brightness of the screen, the brightness is highlighted when the backlight is reversed, and the brightness is dimmed when the night scene is displayed. Generally, the data is displayed on the viewer or LCD screen in numbers or diagrams, of course, the best way is to directly look at the viewfinder or the screen on the LCD screen to adjust the appropriate brightness.

16. Due to the differences in imaging principles between digital cameras and traditional cameras, digital cameras have limited capabilities in reflecting changes in consecutive colors. For the transition of some consecutive tones, the photos taken with a digital camera are usually large areas with a single tone, and the detailed performance is even more difficult to talk about. This requires us to highlight theme as much as possible when shooting items and characters, pay attention to background selection, and reduce background interference. For example, when shooting a static object, the background should be a color with a large contrast with the edge of the static object to avoid the combination of the edge and the background of the captured object, and lose the contour of the captured object.

17. To protect digital cameras and batteries, we should try not to use digital cameras at high or low temperatures, and never expose our cameras to the sun for hours, avoid direct sunlight when shooting to avoid damage to the ccdboard. If you have to be exposed to the sun, you can use a light towel or reflective material to cover the camera. Try to avoid shooting on rainy days and snow days. If you want to take a picture, take proper protection to avoid shooting at low temperatures for a long time and prevent the machine from aging. In the cold winter, it is easy to expose machines from outside the room, just like human glasses. The correct method is to place it in a sealed plastic bag and take it out when the machine and the indoor temperature are the same. Take out the tape and remove the battery when shooting and saving it. Store them in a dry place to avoid moisture on the machine.
