Yo Danny isn't

that just because adjustment layers are created with masks that start out white and can then be painted like a regular layer mask?

Hi Isabel:

Thanks for asking. If it wasn't quite clear to you, it probably
wasn't for other folks.

Painting B or W on adjustment layers works the same way as it does
on layer masks added to regular layers. In this case no layer masks
are involved...just the adjustment layers themselves, which are
added above the target layer(s).

Try this extreme example:

  • Add a Hue/Sat adjustment layer above any color Background

  • Set Saturation to -100 and close the dialog

  • Set foreground color to black and choose a hard edged brush

  • Flow = 100%, Opacity = 100%

  • Where you paint black on the adjustment layer the effect is

revealing the color from the BG below

  • Ctrl + I to invert the mask

  • Ctrl + I again to put it back the way it was

  • Switch to white and paint to "undo"

Black and white are the extremes (100% conceal or 100% reveal). By
airbrushing black on a white mask or white on black mask results in
various degrees of gray (somewhere in between B/W) for controlled

Does this help?

Good observation Danny...are you talking below of a layer mask or a
selection? I assume layer mask.

Great thread. Great idea. I don't believe I read this one among
this collection.

It's not unusual for an image to need color or toning adjustments
in specific areas, not overall. This is my I approach to these

  • Add the appropriate adjustment layer (Levels, Curves, Hue/Sat, etc.)

  • Apply the adjustment to correct/enhance the areas that need it.

usually results in messing up areas that don't need fixing.)

  • Ctrl + I (to invert the mask and "undo" the effect)

  • Airbrush with white in desired areas to (again) reveal the

layer's effect. Airbrushing allows you to control the degree of
application depending on need. (Paint black to "undo" if you overdo
it.) You can fine tune by tweaking the adjustment layer's opacity
or trying different layer blend modes.
