We’ve all had portraits done for school yearbooks, and seen the the backdrops that they use. Some were physical curtains that they would position behind you, but others used a blank canvas, with an image projected onto it, which seems like a more efficient way to do things. If you’re doing portrait shots for someone, wouldn’t it be nice if you could recreate this same effect? You can, and without dropping a lot of money.
This DIY guide will show you how to construct a texture projector from some Fresnel lenses, textured glass, a light source and a few other materials. It’s not a terribly complicated build, with the most tedious task being the measuring of the focal length for the lenses (which isn’t hard at all). As you can see from the pictures below, it really does create a very professional look for your portraits.
