All in all, I think collaborations work well because the more input the better and have a clear idea of what you want and communicate that to the photographer.
^^^^^Yes. This is so helpful when character and/or plot photos are desired ^^^^^
I always ask the cosplayer if they have character poses they'd like to capture. If they don't I ask about the character's personality and just build from there. If none of the above apply I use model poses and work with the cosplayer to get nice shots.
