We Are HDR: Creating HDR Images - The Adobe Photoshop CC - page 329

Advanced and Curves:
Now, on to the Advanced tab (even though these settings aren't really advanced). The top
slider is like a very subtle version of Camera Raw's Shadows slider. It really doesn't do
all that much, even at 100%, so I usually skip it. Highlight controls the highlights (duh),
and I do use this one when some areas (like windows in a church, or clouds in the sky)
have turned gray. Dragging slightly to the right makes them white again (it's not nearly as
good as Camera Raw's Highlights slider). You could use the Vibrance slider if your colors
seem a little dull, or the Saturation slider if you want to take your image to “Harry Potter
land,” but again, the versions here in HDR Pro don't have nearly as much power as the
same sliders in Camera Raw, so I don't use them at all. Ever. Lastly, there is no Contrast
slider here, so to add contrast, click on the Curve tab to reveal a point curve like the one in
Camera Raw (see page 22 ) . Okay, that's a quick look, but you're about to learn a whole lot
more, so let's get to it!
