Hypothetical situation:
If you sell an image or high res. file, and sign away all your rights to that image, can you still sell, or use similar photos?
For example, you set your camera up on tripod, and take two photos without changing anything. The comp, lighting, camera settings are exactly the same. The only difference in the photos is the time they were taken, which is only a split second apart. You sell all of your rights to photo A to someone to do whatever they like with it. Can you then sell photo B to someone else?
Just curious.
