I don't do adult design(except for my own sites)-have done mainstream, but either way, I am not that good...but I have purchased matrix content for games I have made-loved their white background stuff...last time I looked, which was a long time ago, they had the models for the white background already masked out. But the thing was, and I have to imagine this goes the same for designers, is that I always would want 1 or 2 images from a set(they were sold as a set of maybe 45 pics of the same model in different poses)..so it seemed like a waste of money to buy a whole set when I was only planning to use 1-2 images... I think you would have a hit if you sold individual images with the white background(probably even cooler if they were already masked out--would be easy and quick with FluidMask) and fairly easy to set up. Since you shoot a ton already, I think it would be fairly easy to just have a white backdrop you could bring to shoots and get a few quick shots against it at the end(with a plugin like fluidmask-you wouldn't need to have the whole model in a perfectly white background...the hair is the main part, so a white sheet well lit behind the model and a bland floor would make it all easy)
just my
on a side note, I am a huge fan of your stuff
