  1. Thanks for this Karl. Just a quick question, could you also have used a levels adjustment layer to increase the contrast on the label instead, or was the unsharp mask contrast adjustment better for this particular task? Many thanks. Best Will

    1. Hi Will, you can use levels or curves adjustment layers for general contrast adjustments but that doesn’t work in the same way as the USM tool which is essentially a local contrast adjuster as it identifies edges and changes contrast in those vicinities.
