Since I have been adding some new Resources to the sidebar for Exhibition/Artist calls, I have just added the Art Calendar magazine link. On their web site, they have a section called “Calls to“, which includes sections for juried exhibitions (in general, not specific to photography), with a break out between the exhibits you need to pay a fee and those which you don’t. In the section for the non-fee, there is also a listing of galleries who are open to submissions.
For galleries that are open for submission, probably a good idea to read a current article in Art Calender; Vanity Galleries: Pay to Play at Your Own Risk.
Best regards, Doug Stockdale
P.S. thanks to Miguel Garcia-Guzman for pointing to this article out on his blog, Exposure Compensation.
