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
