I just had my first shoot with a model and I've got about 40 images to upload.  I've tried a couple websites but haven't had a purchase yet.. although my images are only visible on one site so far.  I just ordered a book called the '2009 Photographer's Market', which is supposed to give tons of contact information for different places that buy photos.  Has anybody checked this book out?

I recently rented a studio for a photo shoot because I wanted a pure white background, which requires professional lighting.  I'm upset because the background game out beige, and isolating the model in Photoshop is very difficult, especially with the hair.  I know there is a method of isolating an object my using the contrast, but the difference isn't significant enough for that to work.

My question is.. if I were to buy a green background, would that make it easier to isolate the object and place it on a pure white background?

Thanks!
