Me (Roy from perfectexposure.org) and my friend are amateur photographers (although we do some paid work every now and then) and we have created this website

We believe in free culture and we are going to post all our photos in full resolution on our website and can be used under following creative commons license (http://creativecommons.org/licenses/by/4.0/), That means you can remix, transform, and build upon the material for any purpose, even commercially. 100% free of cost.

This modern Pinterest style website has a large selection of images which is nice to browse through or you can start by selecting a category. There are a few textures and hopefully this section will grow.
