I thought it would be interesting to see the differnt outcome for AcrCalibrator with the differnt Nikon D300 D-light sittings. I ran these ACR script twice on each setting to be sure and also the target was photographed in the studio under studio flash.This is a very controlled lighting sit up. The changes are subtle but they are there so use them as you please. I recommend though anyone who is serious about color, should preform their own test.
