I frequently shrink down large images for online photo galleries. What I want to know is, when I tell photoshop, et al, to shrink my image to a certain size/percentage, will it retain better quality if I use round percentages like 25%, 50%, etc, or does it make no difference?
This wholly depends on the resampling method you have Photoshop use. The default ‘Bicubic Automatic’ should yield very good results, independent from the reduction percentage.
