Applying environment maps and bump maps
When using the Balls and Bubbles effect or the Magnifying Lens effect, you can apply optional environment maps or bump maps. An environment map lets you add reflections, surface detail, and nuances. A bump map treats the source image like a three-dimensional surface, in which pixel luminance values determine height.
