I'm always on the lookout for an organization that explores areas for my imagery I have yet to reach... and here's another one: Photo Shelter Collection. I enjoy being part of an organization that looks at what I have to offer and edits down to what they feel is a sale-able product for their customers. AWESOME!
And as you might have noticed, they have a nifty little widget just to the right that will loop what is available for licensing. There is a whole pile of files in the works to be uploaded, many of which haven't been seen before so keep your eye on that little box. Cool stuff awaits.
