Custom Composites...

If, year after year,  you get the same photograph of your child posing at first base with bat in hand...

Or you've taken the perfect picture of your loved one but the background is bland and boring...

Or you bought that 12x16 frame, but you have too many great vacation pictures to pick which one to enlarge...

Or you want to put together that collage of old family photographs...

Then custom composite photography is what you're looking for.

Under Composites & Collages, you'll find examples of more complex, multi-photo composites.  Under New Backgrounds you'll see examples of what a simple change in background can do for your photographs.
