Experiment #1a
Perceived shadows quality vs. masking by texture

On this page you will see seven pairs of images. Compare the left image with the right image for each pair, judging on a scale from 1 to 9 how similar they appear to be. If they are very similar to each other, assign the grade "1" to the pair of images. If they are very different from each other, assign the grade "9" to the pair.
NOTE: The same grades can be assigned to multiple pairs of images!
