I saw a new term in a book, "new photo". What does this mean?

I think it refers to the photography textbook "New York Institute of Photography".

This is a set of classic photography teaching materials, compiled by the New York Institute of Photography. This book gives a comprehensive introduction to photography from the simple to the profound. Learners can master and improve their photography skills through self-study. In addition to regular photography, this book also includes the latest digital photography technology. According to the new version, all the translations are retranslated, the content is about half that of the old version, and they are all in color. Exquisite printing, profound connotation, perfect composition and endless aesthetic conception-this is the perfect photography technology, and it is also the high realm that the New York Institute of Photography will lead you to climb.

The New York Institute of Photography, founded in 19 10, is a professional photography training institution with the longest history and the largest number of students in the United States and the world.
