Looking for advice on how/where to market my form of photography (color infrared model work).  My scenic work sells in galleries, but the model work is still new and I am still green on the business side of model work.

thanks for any advice.

Try e-bay (yes ,I know real "artists" would never stoop so low) but you would be surprised how good it works if the stuff is good enough.Also,it is a good way to sample what the public wants,alot of people use it just to test the reaction to a product.I sold there for awhile and never got stiffed by any buyer,but I never got rich either.
