Seamless backdrop paper has long been a staple of studio photography. So have muslin backdrops, painted backdrops and other materials that can be rolled up or rolled out as needed. But they also take up room, ultimately need to be replaced, and if you're limited to a few choices, can get old and boring rather quickly. So if you're getting tired of the same old look, or if your client wants something different, you might be interested in Savage Digital Backgrounds.
