We show how perceived contrast of natural images, as a function of spatial frequency, is measurable using a novel form of the psychophysical ‘classification image’ paradigm. Contrast spatial frequency weighting functions peak at mid‐high frequencies, and are more stable than predicted by common definitions of image contrast or contrast sensitivity.
