Tips and tricks for digital cameras

Why are there so many differences between the photos taken from the same view and those taken by the same class of digital cameras, don't be upset about your lack of basic photography knowledge, and don't be depressed about camera grades. The following tips can help you reach the level of expertise.

Many users who have already started to use digital cameras often rely on the fully automated shooting mode, which is still good in general environments, but in a slightly more complex shooting environment, then the full-automatic mode is insufficient. The following tips can effectively improve the shooting quality. Even cainiao can take high-level photos! Let's take a look!

"Zookeeper"-avoid the danger of Jitter

A tripod may not be a commonly used accessory for cainiao. even friends with a tripod are reluctant to carry it when they go out to play, shooting in a well-lit environment usually won't experience the hand shaking problem caused by the shutter being too low, but if you don't use a tripod to assist shooting in a dark environment, generally, cainiao do not have the skill of "being steady" when the shutter is less than 1/15 seconds. At this time, the camera is prone to jitter and the photos taken can be imagined. (When the shutter speed of a digital camera is less than 1/30 s, a warning sign of "anti-jitter" appears on the LCD screen)

When shooting with a fixed camera without a tripod, you must learn to use all the methods and terrain to achieve the most stable shooting preparation like martial arts experts. If there is no tripod, you must use the surrounding objects to stabilize the camera, such as leaning against a tree, placing your arms on a railing or other fixed objects. If you use a rotating lens (Nikon 5000, Nikon 5700, Sony f717, f707, etc.) or a digital camera (canon G2, G3, Olympus 5050z, etc.) that can select a display screen, because even on a railing, on the ground, or on the wall

It is very convenient for the LCD to face itself. Sometimes you can even place a digital camera in a place with a basin protruding from the waist for stable shooting.

"high/low decision"-How to Reduce Noise
when shooting a motion object or in a dark environment, you can use the high sensitivity settings, when the ISO value is high, the shutter speed is faster and the shooting is easier. However, a problem caused by high sensitivity is that the image noise points increase, in fact, this is a dilemma for many digital camera users. Low sensitivity, difficult shooting, less noise, high sensitivity, easy shooting, and more noise. In general, we have to narrow down the resolution of the photos taken with high sensitivity, and the noise in the photos is not so obvious, this is a simple analysis because after the image is reduced, a pixel is obtained by merging multiple original pixels. In other words, the three noise points are converted into a noise point, which is not a strict explanation, but it helps us understand this phenomenon.
As a result, we can use a digital camera to solve the difficulty of High-sensitivity noise shooting. However, let's take a look at the cause of Digital Camera noise: when the light intensity is low, the CCD unit cannot sense enough light, after converting an optical signal to an electrical signal, the current intensity is relatively small, and the ratio of the hidden current that CCD uses increases, it can be understood that increasing the brightness sensed by CCD can reduce noise. For example, if we take a digital camera with a maximum pixel of 3 million images at a rate of 1 million pixels, this is equivalent to using three CCD photosensitive units for one use. The photosensitive capacity is equivalent to three times more, image Noise also drops a lot.
the best number of pixels for each camera in the high sensitivity setting requires the user's actual experience. Let's make a metaphor. If they are all in the iso400 setting, it is possible that a 2 million-pixel digital camera has the minimum shooting noise in the 640x480 resolution setting, while a 5 million-pixel digital camera can achieve good results in the 1024x768 resolution setting.

"remove freckles"-avoid displaying dates on photos
most traditional cameras use the date printing function for future query, digital cameras also inherit this function. However, after the photo is marked with a date, you will feel a lot of commemorative ingredients. If it is a very beautiful landscape, you will feel a little redundant after the date is marked. If you do not set a date, you are afraid that you will forget to take the photo later. In fact, all current digital cameras support the EXIF information function. EXIF is a piece of information contained in the photo file header, including detailed shooting parameters such as date and time, aperture, shutter, focal length, white balance, and camera model during shooting. With EXIF information, you can stop playing the date. A digital camera can view this information directly in browsing mode. To view details, you can upload the photo file to your computer and use ACDSee
4.0 or later. The procedure is as follows: first select the file you want to view and then click "properties" to read the file, or directly view the "properties" of the file in Windows
XP system ", then select "advanced" to view details.
using photos taken by a digital camera, you can use the shown method to easily query the attributes of this photo in the ACDSee software, including resolution, image size, aperture size, shutter time, focal length, shooting time, and so on.

Experience 4: Flash for selfies

Most digital cameras use electronic shutter, so they generally do not sound. In order to make it easier for people to perceive shutter movements, a small analog sound will be triggered when the shutter is pressed. Generally, it's okay to take a picture. If you use the selfie function to take a picture when the noise is high, you won't be able to hear the shutter sound. Although there is a selfie indicator, it's not easy to see it in a light environment, because I don't know when to finish shooting, I can only wait for a while like a sculpture. In fact, we can use the force flash function of the digital camera to set the flash mode to force flash when taking a selfie, so that we can see that the flash will be taken over. Don't worry that force flashing will affect the photo exposure, because when there is enough light to take a photo, whether the flash is not obvious from the photo, when the light is not enough, the light should flash.

When taking a selfie, if the self-timer instruction is not obvious, you can use the flashlight to describe it. If the light is insufficient, you should turn on the flashlight to supplement the light.

Experience 5: Wide Angle shooting

The wide angle of many digital camera lenses is relatively small, generally 35-38mm. If the distance is limited to be close to the shooting distance, sometimes you cannot take all the scenes you want to take into the picture, at this time, we can use the features of digital camera photos to facilitate post-production, take one or more photos from the left to the right of the subject as the center, and use the panoramic software to synthesize a photo on the computer, the quality of the wide-angle lens is not comparable. Currently, panorama is a commonly used panoramic software.
