[GRASSLIST:2902] vignetting

[werchowyna at pf.pl]

has anyone delt with aerial photo radiometrical correction in regard of the
vignetting effect?

it's an effect of unequal light distribution in the the wide angle lens

as an effect the center of the photo is brighter and corners/borders are
darker - the
further from the center the darker

my photos cover mountainous area

btw: thanks Markus for your remarks on topographic and atmospheric
correction
