/cgl/ - Cosplay & EGL

How does /cgl/ feel about the responsibilities of cosplayer and photographer at conventions?

Some cosplayers like photographers to have cards saying where the photos can be found after the event, but what if your photography is pretty mediocre and you feel like an ass with a 'business card'?

Is it advisable to prepare more than one pose as a cosplayer to help photographers get a better shot of you?

Is it okay for either party to ask to move to a better location for a shot, or is that asking too much of a stranger that may not care too much about a picture of/from you?

etc.
