That helps me understand what’s going on under the hood and will aid me with adjustments. December 9, 2019 Log in to Reply Nigel Cooper I understand the first technique for adding ‘sharpness’ using the unsharp mask. But when you move on to adding more contrast, also using the unsharp mask tool, won’t those settings then overwrite the original unsharp mask setting that you used to sharpen the image? Or do you use two layers, one for sharpness and another for contrast? How does that work? December 11, 2019 Log in to Reply Karl Taylor Hi Nigel, no they don’t overwrite they simply add, even if I used the same settings you would notice it ‘sharpen’ slightly more. But and this is very very important, remember that sharpening isn’t sharpening, that is actually impossible as there are no extra pixels. All it is doing is changing relative contrast between adjoining pixels in key places to enhance the appearance of sharpening. On my second adjustment with my different settings I’m changing contrast in a different way and different areas of the image. Leave a Comment Cancel replyYou must be logged in to post a comment.
