I'm dealing with a set of photos where a model was photographed against a white backdrop. The problem is that due to the setup, way too much light reflected off the backdrop. So the model's face (for instance) is not overexposed. However, the light coming off the backdrop is so intense, the model's edges are lost, as they fade into white much too quickly, leaving no definable "edge".
I know it may be hopeless, but are there any things to try to bring back some edges without underexposing the rest of the model (the lighting is essentially perfect everywhere else). I have Photoshop & GIMP, if it makes any difference.
Here's an example of an elbow that is almost completely lost. This is actually one of the "better" cases.
