While ENF and exhibitionism are overlapped sometime, (for ENF) a girl doing exhibitionism act should be the type where she does it to get the thrill from the risk that she might be seen/discovered (but dislike the idea of actually being seen and become embarrassed if it happens) NOT the type where she does it to show her body to everyone and happy to be seen.
For your question, I think there are many manga/doujin with nude photography or nude model for art club.
