I wondered about this while reading a thread on a LARP site where people were discussing whether the economic downturn would decrease GWCs or give them an edge.
I think it is frustrating for any artist trying to get by to offer someone a totally fair and commercially viable rate and have them come back with the rate a GWC gave them. The whole point is that a GWC is not basing their rates or policies on being a professional artist, so, when paying a model a gajillion dollars an hour or whatever, a GWC does not have to factor in how little they will actually make from wherever the work is likely to be published. I do not think of GWC as meaning someone who is untalented or a beginner necessarily, just someone who is holding the camera for reasons which have little to do with the final image.
How do you define GWC?
