Image Synthesis Class

Homework 11:

Add the ability to naively tone map high dynamic range images in your raytracer. I also wrote a simple program to tonemap high dynamic range images in RGBE format.

NOTE: All images are gamma corrected with gamma 2.

Effect of Tonemapping with Changing Light Intensity:

Original image (from last assignment)	Tonemapped with parameter M = 0.2
Scene with a very bright light	Tonemapped with parameter M = 0.2

Effect of Changing Parameter M:

Original Image (same as above)

M = 0.02	M = 0.06	M = 0.13
M = 0.20	M = 0.42	M = 0.6
M = 0.9	M = 1.3

Results on Common High Dynamic Range Images:

M = 0.02	M = 0.08
M = 0.2	M = 0.4
M = 0.02	M = 0.08
M = 0.2	M = 0.4
