About 18 months ago I opened a small gallery in Bosham, West Sussex with my girlfriend who makes mosaic tables. It is called www.up-the-creek.co.uk
The hardest part was hitting the price for the customer base. The past 6 months have been very good with about 1 to 2 print sales per week (various sizes) being sold. Local prints go down very well as do my floral studies. I have just recently set up online ordering.... but this will take some time to get off the ground as marketing budjets are very low - this is a self-funding hobby at present :-)
And yes I do buy other photographers work.... if others buy my work, then I should buy others.
photography is an art of expression.
