Shorter Version:
Are there any loopholes in the U.S. copyright laws that could be exploited in order to maintain the rights to a certain version of a photo which has been altered only slightly from the copyrighted version for which I no longer have the rights to?
Longer Version:
I have submitted a few shots to a publishing company and I was wondering a few things about the copyright information. Their terms and conditions essentially says that if the company decides to use my photograph then I will be asked to sign a contract in which I will give up all of my rights pertaining to the photo including the copyright for the image. Now here's the question... If I submit said image (and loose the rights to that image) can I still hold onto a very similar image whose exposure has been altered the slightest bit and still legally posses all rights regarding the photograph?
Thanks for reading everything I had to say.
