I understand what you are wanting, You want to be able to build a magazine of the photos you have done that could be used in a challenge or some sort of way i like it .... 

To add to this i think like the expo asks for moves for bonus points there should be something like a quest or challenges to do films or photo shoot of what is needed ect...

As currently its all getting rather repetitive - and this is where you lose some of the player base, need to keep spicing it up.
