The photo in the background and the sphere has diffusion 60 ambience 40 using the image for both. Refraction is 100 (air) because I didn't touch it. Everything else is zero. Tried turning on, off, cast shadows, receive shadows, self shadows, and blend transparency. The infinite plane is deleted. Atmosphere is off Black didn't help. White Didn't help. Tried mapping to a cube instead of a 2D surface with no luck. I'm using premium render. Went in and turned off all four optics settings one at a time with no effect. Oop's, I feel stupid. I had used square lights at first when I had the spheres pointed up in an attempt to create the effect of florescent tube reflections. Even though the flat wall was below these it still had an effect on the surface. I deleted all square lights and replaced them with radial lights. Everything looks real, (Except the table texture). I've noticed I have a lot better luck using objects with the ambience cranked way up than actual lights if I want to simulate visible bulbs.
