Historical evolution of traditional photography?

It used to be a manual camera, then a semi-automatic camera, then a fool camera, and now it has developed into a digital camera. The photos have changed from the original black-and-white photos and monochrome photos to color photos. It is more troublesome to modify the negative with photos taken on film, but it is easier to modify the digital negative. However, to make good works, we must learn PS software well. This is an outline. Work hard and wish you a good paper.
