Can't delete Layer Mask content in PS CS4.

I am completely baffled with this and am thinking that it's something obvious I am just missing.

I have a photo open and click on the "Create new fill or adjustments layer" button at the bottom of the Layers panel.

In CS3 I able to create a layer (say Levels) and apply it, then select the eraser tool and delete sections of that adjustment layer that I did not want revealing an unaltered section of the original photo behind it.

I can not seem to do this in CS4. I can add the layer and select the eraser tool but it will not delete anything.

:s Help??

Thanks.

not sure if i'm 100% following your question but, in general, working with masks, don't use the eraser. paint with black to add to the mask, paint with white to subtract from it...

Hi,

CS3 has buggy targeting behavior, which has been fixed in CS4. You have to make sure and explicitly target the Layer mask in order to affect it.

Thanks Dave! I tried that out and it works much better than what I was doing before. Your way gives me a non destructive edit that I can change later.

Thanks a million!!

Steve, you are 100% correct and I did not notice that before. That was a big help as well. Thanks.

good point. make sure the mask is selected first. :)
