Tammy and I also maintain another website-JaxPortraitLounge (jaxportrait.com) where we have a blog geared toward photographers and sell a few digital layered backgrounds and digital props to photographers. Trying to simplify am going to slowly merge the two sites together. The backgrounds are shown under "photographers Corner" on menu
Most of our props are designed to look as a studio setup to give them a realistic look as if they were actually taken on location or in a studio. We take great care in making our backgrounds and digital backdrops. Check them out!
In process of making tutorials on using the props that I hope will be available soon but there are plenty of tutorials on web. Only 10 posted so far but have several more waiting.
