This is a retouched picture, which means that it has been digitally altered from its original version. Modifications: SVG-ified version of File:Psychophysical.jpg. I tried to make the image look exactly like the original, and I tried to keep the overall style the same, but the original was such a low resolution that I was forced to take a little artistic license (mostly just improvising details that were unclear, some minor color correction).. The original can be viewed here: Psychophysical.jpg: .
