Expiration Notice is an on-line magazine dedicated to work by emerging photographers over 35. An interesting counterpoint to the usual hyping of "young and emerging artists." (via)
"The Pulp Gallery is a visual reference guide to the wonderful cover art of pulp and pin-up magazines." From the bizarre (Lovecraft!) to the breezy (NSFW?), the savage (Any relation to Adam?) to the spicy (Eel Trap!). And don't miss the gallery of recycled art.
Nature Photographers - an online resource dedicated to the art and technique of nature, wildlife and landscape photography.
FILE - A Collection of Unexpected Photography - "FILE Magazine publishes images that treat subjects in unexpected ways."
Smithsonian Magazine is holding its first-ever photo contest, open to all adult non-professional photographers to submit entries in five categories. (Professionals may want to see about freelance opportunities here.) I find it particularly nice that there is no entry fee, and no citizenship requirements. For inspiration you may want to browse a gallery of Smithsonian freelance photographers or view the beautiful (and seasonally appropriate) Ghost Towns by Night Light and pick up a few tips on night photography from the photographer.
