What do you think is the main function of photography?

I think photography is for recording. Just for recording, it doesn't matter if you don't take pictures, as long as you ensure that the things at the moment can be completely preserved by the camera, regardless of composition, lighting, shooting skills and the psychology of the subject, or body movements and expressions. The problem is that we should not only record, but also record methodically, aesthetically and artistically, which requires some shooting skills. Of course, I wouldn't expand it if it were him. So I think you can do it boldly. As long as the purpose of recording can be achieved, the significance of taking pictures will be achieved. About how to shoot well and how to shoot well, these are all photography skills, which have nothing to do with the meaning of photography itself. Photography can save and share images. Saving allows images to travel through time to the future. Sharing allows images to travel through space to a distant place. Therefore, photography is a means to make images travel through time and space: visually, a time dimension that can go back to the past and a space dimension that moves at the speed of light are added. You have become a better person.
