Indirect Lighting of the "Cornell Box"

The following image was rendered with 1024 samples per pixel, with only one sample per light for the direct lighting calculation. Also the image was gamma corrected using 1.7 for gamma, to brighten it up a bit. (The computation took, well, a long time.)

The image below uses only 36 samples per pixel. Note that the general lighting trends are apparent, but areas receiving mostly indirect light (such as the ceiling) are very mottled.

256 samples per pixel
