And the Highlight/Shadows adjustment, when you select to show more 
Options, allows infinite adjustments, and an ability to save whatever 
you wish as presets.

Its not the same thing as shadow/highlight. Curves operates on the whole
image equally. Shadow/highlight (I'm talking CS2) first decides what
is a shadow area, or a highlight. You can adjust the cutoff points. But more important,
it does not decide based on individual pixels. First it makes
a blurred image of the whole picture, where the blur radius is
adjustable from 1 to hundreds of pixels. It then decides
what is shadow or highlight based on the cutoff values you decide,
from the blurred image. The result is two masks, one that selects
highlight areas, one shadows. These masks are not sharp edge, the
edges are feathered. You can then adjust the contrast of
the highlights and shadows separately. The areas of the highlights that
were near the bottom intensity can go well down into what were shadows,
and the areas of shadows that were lightest can go up into what were
highlights. You can also do some color saturation correction.

If you select a small blur radius for the masks, it looks
like a crude old-fashioned darkroom silver mask. If you select say
400, it looks very different and much more pleasant.

This is a very useful tool for landscapes.

What is wrong is that using either curves or cs2's shadows/highlights
[advanced option] does not do quite as well as the ACDSee version, and
is harder and more time consuming to use in any case.  Levels won't do
the trick at all.

JOHNCHAP2 is a spammer promoting ACDsee.

What a surprise! He certainly doesn't know how to post. Where did you 
get your info?

They don't do anything at all for local contrast.

For example, in the highlights you might want to just pull down the darker 
areas, and in the shadows, pull up the brighter areas.

I certainly hope that you fellows in the Spammer Inquisition have ample 
evidence to suggest that this person is a spammer.  It seems that far too 
many people like to label people spammers without any real proof.

your lack of knowledge how to use curves and the other features of PS does 
not mean PS is inferior to whatever else prog
it means you  have-not spent the time understanding how to use the options
and OTOH if ACDC is so fantastic or this task JUST USE IT INSTEAD

in either RAW dialog and/or LAB MODE
you can work with gamma only

in curves in LAB also

make sure to use the advanced dialog inthe shad/highlight dialog

and PS since 4.0 you can save any setting
in any dialog

You can do that with curves by adding more control points and making odd 
shapes as needed. The advantage of curves is you see the structure of 
what's being changed: you can see if the shadows are raised & highlights 
lowered, the midtones lose contrast (become more horizontal). Using 
masks as 'user' describes is something different. That sounds like it 
could be a handy tool though it's not hard to make quick masks with a 
big soft eraser on curves adjustment layers... more control that way.

Curves are awkward though, I'll grant that. One thing that helps is 
dragging the cursor over the image with the control key held down, you 
see that tone on the curve. I generally set the adjustment layer's 
properties to luminosity so it doesn't effect saturation... at a 
saturation layer separately if that's desired.
