Please objectively evaluate the photography textbooks of New York Institute of Photography and New York Institute of Photography.

New Photos should be said to be the most classic of introductory and advanced books. As you said, many knowledge structures in the book are from the 1970s and 1980s, but that doesn't mean they are useless. Because its imaging principle is the same in the film age and the digital age, knowing the purpose of film is not harmful to a person who wants to learn photography. Moreover, most of the knowledge points in the book, whether it is the previous film imaging, the current photoreceptor imaging or the future imaging, are bound to be useful as long as they are single-lens reflective systems. The book's discussion on the relationship and comprehensive application of photographers is quite exciting and vivid. It can be said that buying a new set of photos can not only save money for buying such basics, but also save a lot of time for learning such basics.
