GRD II Review, Supplement


Hall of Famer
I sometimes use 50% crops viewed on-screen as a cheap surrogate for a print comparison. As a supplement to the above review, here are 50% versions of the crops used in the resolution test. Recall that that test compared native size GRD images and DP1 images which had been upsized to 10MP using Genuine Fractals 5.

The first set shown below (Set A) has been simply resized to 50%. The second set (Set B) has been resized to 50% and subsequently had a large radius USM applied selectively to increase local contrast in the GRD crops. In all pairings, the DP1 crop is on the left and the GRD crop on the right.

Set A:


Set B:
