Which file format should the camera use when taking pictures?

1 and JPG(JPEG) formats are common photo formats. Digital photos stored in this format can be used in all kinds of characters, and the picture browsers of computers and smart phones can also display normally. However, the image file in JPG format is compressed (divided into 1/4 and 1/8, the compression rate is116). The advantage is that the file capacity is small, but the disadvantage is that this compression is not good for image quality. In addition, after the camera is set to store JPG, the captured picture information is processed by the camera's preset retouching effect, the most typical one is the white balance preset, and it is irreversible to store the picture in JPG format after retouching. In case the white balance setting is wrong, resulting in the color cast of the photo, even if the PS software is used for strong modification, the effect will not be very good and the image quality will be greatly reduced.

For ordinary users, usually the file format of the camera should be set to JPG fine (low compression rate and high quality storage).

2.RAW format is the favorite storage format for senior photographers. It can be called the lossless recording format of the original information. This format stores raw information from sensors. Different manufacturers have different recording methods. The suffix of Nikon RAW format file is. NEF, and canon's RAW format file is. CR2。 Therefore, most picture browsers on the computer do not support this format of picture display, which is a non-universal photo format. The biggest advantage of this storage format is that the information has not been processed by the camera, and users can adjust the photos (sharpness, contrast, white balance and color saturation, etc.) to the maximum extent. ) Use special software. As long as you pay attention to accurate exposure and focus when shooting, you don't need to consider the setting of white balance at all. Through careful post-processing, a beautiful blockbuster can be formed. The disadvantage of this format is that it must be post-processed and then converted into JPG files, which requires a lot of work. Photographers who have high requirements for photo quality don't care about this heavy post-work. In addition, RAW format files occupy a large storage capacity, and photo files with 36 million pixels of picture structure and complex colors can reach more than 30Mb.

Choosing a high-end camera generally has a dual card slot. I am used to storing original files in the first card slot and JPG files in the second card slot. The storage mode is original +JPG fine.
