Most licenses for Personality or likeness of a human allow restrictions on the way that image is to be used. I can't take a picture of your mom, and then have it be used in an ad that implies she has STD's. With good reason. If I posed a model to look like she was basting a turkey for thanksgiving, and then modded the image to be part of a pornographic image she would now be a porn star rather than a cooking personality. She would have no problem being in a derivative work that added titling or changed the color of the walls, or featured a different brand oven, but probably wouldn't be ok if the image was modded to look like she was inserting a turkey baster in to a persons rectum.
