Do photographers nowadays have to understand PS?

Personally, I think:

1. In documentary photography, such as documentary photography, scientific photography, life photography, documentary news photography, and humanistic documentary photography (street photography, historical photography, and PS ban), you don't need to learn PS.

2. In artistic photography, such as artistic and humanistic photography (wedding dress, portrait, business), landscape still life photography (landscape, flowers and birds, still life, etc. ) and exploratory photography (creative photography, computer synthesis), you must learn PS!
