Layer masks: how do you memorize which color means opaque?

Hi,

i'm curious how other people regard layer masks. In particular, which memory aids exist to remember when to use black and when to use white.

Two contradicting examples which both seem to survive inside my head:

- the (correct) math perspective: black equals zero, zero opacity means fully transparent

- the (wrong) book example: black is where the letters are printed, that is where the layer is active, that is opaque.

This one frequently lets me stumble for a split second, especially when working on a mostly opaque mask over a white background layer..

Obviously, the very question tells i'm using masks not that often.. How do you handle the situation?

Do you use a memory aid to remember when to use black and when to use white? Or does it seem just natural to you, so you don't have to think (anymore)? How do you explain the "white means opaque" relationship when teaching masks to other people?

regards, peter

I think of it like illumination. Black is no illumination, can't see a thing so it's transparent, white is fully illuminated, the thing shows up clearly, so opaque. (Really I think of it in rgb with black 000000 means nothing is there and white ffffff is fully turned on, but that translates to illumination for those who don't think quite so technically as I.)

Cool. I think of it as a window or transparent overlay.

Thank you very much, Patrick and Chris, for sharing your style of thinking. It's very interesting to learn how different the mental concepts/mnemonics are.

If other variations are in use, please keep em coming!
