We exploit the prior on the spatial distribution of average log-luminances to estimate the vignetting for lens settings of specific camera models.

Here we show the vignetting estimated for two lens settings each of Canon S1IS, Sony W1, and Canon G5 cameras, using their respective average log-luminance images. For these estimates 15,550, 13,874, 17,819, 15,434, 12,153, and 6,324 photographs, respectively were used. (f and N stand for focal length and f-number respectively.)
