AP photo 2006 Mannie Garcia\Shepard Fairey

Here's an article about one artist using a photograph that was taken by another. This is a very good example of how sticky this issue can be: Calif. artist sues AP over image of Obama.

Personally, I feel "do unto others as you would have done to you" was unfortunately overlooked. It would have been wise, and respectful for Fairey to talk to Garcia first about what he wanted to do and seek permission. Credit should have been given to Mannie either way because that is the right thing to do. I honestly feel, more than ever, that we artists need to respect each other's work. See my earlier post on copyright.

What do you think?
