Any way to create a mask on an adjustment layer?

I'd like to adjust the brightness/contrast on a certain area of an
image. Ideally I'd like to use an adjustment layer and create a mask
on it to hide everything except the area that I want to adjust the
brightness and contrast. Can I do this?

No, You'll find that the mask is 'Grayed Out' for adjustment layers.

However, you can place a selection in the image (Selections are
universal), then, with a layer selected from the Layers Palette,
create an Adjustment Layer that will effect all layers below it.

The effect will only go inside the selection.

Another trick you can use is painting inside the adjustment layer,
after it's been created. Often, you can paint in the effect with
white, or eliminate it with black. Gray colors are in-between,
Effects vary, experiment.

Sure you can. Duplicate your background layer, then make the selection
you want on your copied layer. Go to the menu Masks/New/Show Selection.
Now you can make your changes to only the selected area.

Have fun...Scott

Wow, I didn't know you could do that! This does exactly what I
wanted. Thanks for the tip!

Is there a way to view the adjustment layer itself while you are painting on
it (i.e. the grayscale "mask")? The only way I've figured out to see it is
in the little thumbnail that shows up in the layer palette when you hover
the mouse over it.

Just make the adjustment you want with the layer and then
use the eraser on the adjustment layer to erase away the
adjustment in the regions where you don't want it.

And if you are using the Overlay adjustment layer (one of my
favorites), you can paint with RGB=128,128,128 to get
no effect.

Did you mean setting an Overlay blend mode onto a New Adjustment
Layer? Why not just simply use the eraser on the adjustment
layer itself? Its brush settings on the tool options palette
offers us full control over the opacity of the eraser and the
softness/hardness of its edges? How I love that eraser and PSP's
reverse erase (unerase) option that's built into the rightmouse
button.

I'm extremely fond of those adjustment layer too, and don't even
get me started on blend modes. :) One of my regular (most
favorite) uses for Adjustment Layers is to apply the layer to
get a general overall preview of how it looks on the entire
image. Then I right-click the titlebar of the image and CUT that
entire adjustment layer away. Using the eraser and its reverse
erase feature (by using the right mouse button) we can
rebuild/repaint the effect back onto whatever portions of the
image we desire. What I most particularly enjoy about this
method over others, is the immediate availability of both the
left and right mouse buttons, in order to "add to" or to "take
away
from" my effect simply by changing mouse buttons whilst painting
seamless effects with my zero hardness big fat eraser with its
seamless blending edge.

All that New Adjustment Layer correction data that was CUT away
is still there available for reuse, simply by reverse erasing to
apply the effect wherever we want it. If we overdo, or get
sloppy, or change our minds - simply switching mouse buttons on
the eraser allows us to erase rebuild, erase rebuild and better
blend, ad infinitum until we get it just the way we want it.

From the lack of response to this question, I should probably assume the
answer is no. But I want to try one more time. See the question below.

Perhaps you are a little confused. An adjustment layer is a
set of instructions for modifying the pixels of an image; it
is not a collection of pixels. Thus, I'm not sure how you
expect to be able to view it. As far as I know, you only see
the adjustment layer through its effect on layers underneath
it. You can't somehow see the actual instructions for changing
these underlying layers. When you make the adjustment layer
the active layer you will see that the color palette changes
to the greyscale palette for masking. By painting with black
(or with the eraser) you make a hole in the adjustment layer.
You can fill it up again by painting with white (or unerasing).
Grey modifies the intensity or degree of adjustment. You see
these holes or partial holes in the thumbnail of the Layer
Palette. (You can't, however, see the adjustment itself in
this thumbnail view.) Just as it is helpful to see the layer
you are masking when making a mask, you paint on the adjustment
layer (or delete selections from it) while viewing the effect
on the underlying layer(s).

That said, I have often wished for a ruby lith like View Mask's to help me
see where I have painted when selectively applying a subtle adjustment.

If you can't see the effect and need a ruby lith to visualize
it, you probably shouldn't be doing the adjustment :) And if
you do get a ruby lith you'll try adjusting a picture of flames
and tell me you can't see the ruby lith :) Comment noted, however.

You are correct; the only way to see the adjustment layer data directly is
in the thumbnail view on the layer palette.

If you have PSP 5 on your system, or indeed any imaging app that is not PSP
6 or 7, you can copy the layer to the clipboard and paste it to another
application. PSP 6 and 7 will realize the clipboard data is an adjustment
layer and always paste it as such, but other application will just see a
greyscale image and paste that.
