Digital BW, The Print

I apologize for this question in advance but I am apparently drawing 
a blank.

I work all the time in Photoshop to prepare by images for printing.  
One of the process I go through is to make adjustment layers for 
different corrections &/or effects and then add a layer mask to 
feather back the portions of each different layer I wish to have show 
through the final image.  All normal enough workflow.  All of a 
sudden I am having an issue that has never happened to me before and 
I have now spent all day trying to resolve.

I can no longer observe any changes on the screen that I make to an 
image when painting to expose or unexpose portions of a layer onto 
the image below using layer mask.  This is driving me nuts.  Opacity 
& flow are both set to 100% but I cannot change the image to either 
show or hide what is below.  This carries over to every image I open 
in Photoshop.

I am sure I have just inadvertently changed a setting but cannot 
figure out what.  Any help would be appreciated.

Thanks,
Bruce Varner

Hi Bruce,

I have done that several times.  In my case I inadvertantly had 
unchecked Preview in the Adjustment layer.  I'm sure other problems 
could explain it as well.

Can you see the paint building up on your mask? Option/Alt-click on the
mask in the layer stack to show the mask by itself.

If not, you probably have your painting tool set to a mode that does not
change black and white, ie, screen on white or multiply on black. Check
to make sure you don't have a painting mode turned on.

Also try other brushes. It's possible to set brush options so that
nothing happens under certain circumstances.

Does anything happen when you set foreground to black and paint on a new
white background?

If none of these solve the problem, reset Photoshop's preferences.

Good luck,
