>trying to remember photos
Wut? I will do that but what's the point? I had built my visual library basically just by doing life drawings, there is no sense of depth on photos as in real life
There is nothing better than sketching real people or whatever
what does visual library have to do with remembering a particular photo? it would actually make more sense if the cropped out picture was provided by a different anon so you had to fill in the blanks from imagination
So you try to understand what is depicted and remember the photograph, then you copy the photograph but not really because you're applying this in your own way, just remembering the photo but not copying it, applying what your remember and what you understand by looking at the photo and copying mentally what you've seen?
