This "before and after" video represents how the photos provided by my clients were transformed for their montage.

I take great care to make the most of every photo that my clients select for their montage.  For some photos I completely change an irrelevant/busy background to focus on the people in the photo.  On photos where the background is important, I use a 3D program to create space between the subject and the backgound, giving the photo a true 3D look.
