Lightness/brightness experiment • We investigate the impact of lightness/brightness perception upon the perceived contrast of textures. The estimated luminance to lightness functions are similar to Whittle (1986). Whittle felt the non-linearity was composed of a global non-linearity and a local 'crispening effect'. • Experiment One. Task: Adjust the luminance of the below test patches until they appear to linearly transition between black to white.
