I am a photography student that took pictures of my roommate in our apartment as well as in public places. Currently, 2 years later, we are not exactly on good terms and she recently emailed me saying that I needed to remove all the pictures that have her in them from my portfolio website. I don't have a model release form, as I never would have even thought about that in those days. Am I stuck having to remove the photos? If it was one or two or even three photos I wouldn't mind removing the images. However, the images of her comprise almost my whole "portraits" portfolio, which is why I'm at least trying to find out if I have any hope of keeping them up. Additionally, do things change if she's not recognizable? In some of the photos her face is not shown or she is largely obscured. Any advice would be much appreciated!
