Michael, what is the purpose of the 'show'? Is it to sell prints - possibly, or just demonstrate ulf, photography in general, etc. etc. The reason being is that I am a big believer in the 'finished' print. I never let a print go out that hasn't been properly matted and mounted...i.e a finished print...whether it's for show or 'tell'. If we want to demonstrate the 'art' of photography and the magical quality of ULF and contact prints, might I suggest a different approach?

The other issue is that you are only dealing with a week which is tough to get adequate exposure?

Just some thoughts. Again, meant to be constructive, please..

I am only tyring to help here....and I would eliminate print exchange as it will only make things more difficult for you...just one more headache you don't need.
