Hey ivan,
good point about a worthwhile project.
I just wouldn’t want this project to peeter out because nobody gets around to doing a project with 500 images just so.
So I would say we can do it parallel - looking for a nice image set that already exists and the result is known, and whoever feels like it can go out and shoot to impress! 
Michal, how about the stag in your showcase - would that be suitable/available?
