  Because, appart from being almost necessary to create "augmented
reality", it is a very cheap way to fake a complete environment for
close-up shots, including the lighting, with maximum realism. 

  Indeed, I've made some more tests with "faked HDRI", this time with
a 255 layers texture. The first layer is the simple image_map with
ambient, and the other 254 are done with a grayscale version of the
same image, using exponential transmit. Not bad results, and very
quick to render (well, not much more slow than a single layer
texture).
