How do I clean up the edges of a mask?
I opened up a new layer to create a mask to protect part of an image. The thing is I now have parts of the mask which have bled into the space I wish to adjust. I’ve tried using Quick Mask to paint over the area I want to subtract from the original mask, but even at a 1 pixel wide tool size it keeps trying to add more to the selection than what I’ve actually selected. How do I modify the edges of a mask to literally only those pixels I want to add/delete? I don’t want Photoshop to “help” me by guessing at how much I’m really trying to select. Using CS3 on a Windows 7 platform.

I’ve done a bunch of searching here and online and can’t seem to find if this is possible.

Ctrl Alt R might help.
Or LAYER-Matting-….

the limits of resolution is one pixel: even though you THINK you can split the difference, one pixel is one pixel. If you’re at 1600% zoom you probably think you can get between them. You cannot.
What you want is to make a translucent mask at that border pixel. Use some transparency on your brush, or feather the selection.
