Getting Back Shadow/Highlight’s Factory Defaults
Don't ever be concerned about experimenting in Photoshop CS2's amazing Shadow/Highlight featureâ”mess with the sliders all you want, because you can always get back to the factory-default settings, even if you've overridden them by saving your own defaults. You do this within the Shadow/Highlight dialog (under Image, under Adjustments) by clicking on the Show More Options checkbox. Then, hold the Shift button, and you'll see the Save As Defaults button at the bottom of the expanded dialog change to the Reset Defaults button. Click it, and the factory defaults are back, baby!
