3D in Photoshop CS6-CC - 08 - Image Based Lights
Photoshop CS6 and later offers the traditional light sources for your 3D models: infinite lights, point lights, and spot lights, all fully customizable. However, there's another kind of light - an image based light, or IBL - that has some special features. We can use any image as a light source, and in doing so, we can help our 3D model to more closely match the colors of its environment, adding an extra touch of realism.
