Don't forget about our photomanipulation contest:
I want to remind you that, if you are going to use png or psd stock, you need to make sure the stock provider has stated where they got the stock from. If you don't know, ask. If you are still not sure, don't use it. Stock providers need explicit permission from the original photographer / provider to share stock that is not theirs with you, even if they changed it.
The same thing goes for premade backgrounds. Sometimes, stock providers will get stock from places like sxc.hu or even pay-for stock sites like shutterstock.com, and then they make premades out of that stock and offer them to you. This is illegal UNLESS the stock provider has EXPLICIT permission from the ORIGINAL photographer and/or stock site to do so. So, again, check with the stock provider and make sure the stock is legitimate before using it.
On the other hand, this is an "extreme manpulation" contest designed to test your boundaries and push you beyond your limits. Why not make your own backgrounds and cut out your own pieces of stock?
I have already declined a few pieces with bad stock, and I don't want to decline yours. You only get 2 entries, after all.
