Masking - I must be missing something simple.

[delpi767]

I create a new document.  I create a layer of colorful flowers. I duplicate that layer. I adjust the top layer to Black and white.  If I erase on the top layer,  the color below shows through. 

Now I create a mask on the top layer and paint on it in black and nothing happens. So I try painting in white.   Nothing happens. 

What in the world am I missing? 

Thanks

Could be lots of things (e.g. opacity at 0, protect alpha enabled, wrong layer selected, etc) 

The quickest way to resolve would be if you could upload a full size screenshot with the brush tool selected and the layers panel in view and any collapsed layers expanded

Thanks,

I have uploaded a screenshot.

Note that the mask icon does not reflect any drawing I do on the mask layer.

You have Protect Alpha selected in the Context Toolbar

Untick that and try again

Thank you sir.  All is well now.

I very much doubt that Carl is on speaking terms with Boris!
