In the past, photography in the film age was said to be "three-point photography and seven-point darkroom", which showed that the later stage of photography was more important than the earlier stage.

Now is the era of digital photography, and it should still be "three-point photography, seven-point later".

At present, quite a few photographers use advanced SLR cameras, but the photo format is JPG, which is a mistake.

Playing photography itself is the post-stage, and the post-processing technology is high, which can make the photos icing on the cake.

With SLR photography, you should use the RAW format, and then readjust the exposure, white balance, color, lens distortion, lens dark angle, composition, etc. of the photo on the computer in order to get a complete photo, which is also the fun of playing photography.
