Erasing trough several layers

[lassech]

Hi all,

I've spend some time Googleing to find answer to my question.The same way I've searched theese forums for same topic. All of it without any outcome.

Well partly it's because the question i have is not simple explained. Anyway here we go:


In a .psd-document, I'm working in many layers. Each layer has a different color. What i want to do is to be able to erase trough seveal layers a time with an eraser with some 'softness' and some 'opacity', and just a tiny bit of 'hardness'. The eraser should affect the upper layers more than the lower layers - ideally in an exponential-curve.


I've made a muck-up erasing manually less and less trough five layers, just to let you know visually what i want to do:




The erasor takes away alot of the first layer, but barely touches the one lowest.


Any help from you guys in this adventure?


THANKS

Lasse

Not erase but use layer mask. So paint what you want to erase with black in mask and copy that mask to each layer. With curve (in mask) change how dark is that black. That's make sence to you?

Aber of course! (wrong thread..sorry)

Thanks for quick reply. I get where you are gooing. Would there be a way for me to activly paint affecting all layers (their masks) at once? So I would'nt have to copy the masks every time something new has been painted?

only one layer at a time that I know of

Yes, thats will depend of layer structure i think but if it kinda linear then try that:
1. Dublicate layers which need erase.
2. Make group of them
3. Set group mask to total black.
4. Lower each layer opacity depending to how much "eraser" should affect it. Like you want to erase 90% of it, set opacity to 10% etc.

Result, looks like nothing is done to image.

Now paint with white (change opacity of brush if needed).
Places where is "white" will show "erased"(lowered opacity) layers.

Worked for me.

Forgot mention that "background" (white or picture) on which layer are need to be copied too in that group or trick will not work.
