I am a beginner in photography. Is it necessary to read the photography textbook of New York Institute of Photography?

I have read the book of this film, and I can tell you responsibly: Not applicable. The reason is that film and digital are two kinds of media, and different media lead to different exposure methods.

But some principles need to be inherited from these old textbooks.

1, white plus black minus.

2, the principle of metering and exposure

etc

The difference between film and digital lies in the choice of photometric part, that is, the difference of exposure benchmark. The film is based on the dark part, while the figures are based on the bright part. If you read the movie textbook and put it on digital, it won't work, but it will lead to your confusion.
