When I am using this and check the Tweak checkbox dialogue box comes up showing output values with sliders. I believe this prevents some of the dark areas and highlights from being sharpened. How do you know how much to move the sliders? Actually if someone could give a simple explanation of both input and output values that would be great. I have looked on the internet but some of explanations are complex for me. I don't that much detail. Or at least I don't think I do. Thanks.
