We depend on the artwork of others all the time.
We seek inspiration, help, motivation or we need an element for our own projects. I have often found the one-little-something that I was looking for to start or finish a piece of work in the glorious realms of the internet or here at deviantart. So I thought it would be time to give something back and to put some of my photos out here for everyone to use. I might not offer things that are astonishing or special, but well, that is your part: to take the photos, to transform them, cut them into pieces and rearrange them, combine them with others or with your drawings, to create something new.
Just go ahead.
Use whatever you need. No strings attached. If I don't want you to use it, I wouldn't put it here. If you want to show me what you created, I am curious and interested, if not, than... well... don't If you want to mention where you got the material from, do it. If not... again... don't.

There is only one rule:
enjoy!
