That is kind of a "please proof-read an articles conclusion"-question. Some time ago I found this page: Gamma error in picture scaling.
I grasp the point, that the luminosity-curve is not linear and that some (most) software does assume a linear scale and thus resizes badly.
But as I do not have so much experience in the field of image-manipulation / gamma / etc (just starting with the fine points of post-processing), let me ask you: is this guy right about this error during resizing? Is his method to determine erroneous software correct?
