Hmm. Well, you can use selections and masks, but you can use them on anything. I just read the documentation on it and also looked at a couple of website tutorials. It looks like it has some ability to automate what I do with adjustment layers, curves and masks, but why they didn't put it in an adjustment layer I don't know. Adjustment layers allow you to make corrections without touching the original data. The only way I'd use this tool is the same way I use sharpening and noise reduction tools ... make a layer copy of the original image first, then operate on that layer copy. It increases the size of the files and the save time.

I like to be able to go all the way back to the original RAW-converted image at any time in my adjustment workflow to see exactly what the rendering adjustments have done. Easy with adjustment layers, a pain when you are modifying the original data.

I'll play with it a little more. Sometimes I wonder about all these more automated image-processing tools... I like knowing exactly what a given tool is doing.

Godfrey,

You can use a selection and mask in Shadows/Highlights as well, and, at
least for me, the results can sometimes be superior to levels and curves -
far superior. IAC, it's another tool that can help you achieve good
results - you really should give it a try.

I'll have to learn more about it. I don't know how you can target more
narrowly than adjusting Levels and Curves in adjustment layers with a
mask to control what is affected. It may be easier to use
Shadow/Highlight controls, but more precise/narrower? I'll have to be
convinced. ;-)
