Hi all

Wondered if you could help with a frustrating problem that has started occuring with my installation of Photoshop CS, working on Win XP Pro SP2.

When working in Quick Mask mode, the functions of the brush and eraser tools seem to have reversed themselves, almost, but not quite. Let me try to explain:

OK, so I open an image and make a rough selection with the lasso, then enter QM mode.
Now, if I use the brush, it actually erases the red area. If I now exit QM, it has actually expanded the selection area, as you would expect with the eraser tool.

Re-enter QM and select the eraser. That actually paints in red, but when I now exit QM, no modification to the selection area is apparent.

This is not intermittent, it happens all the time and started about 2 days ago. It is driving me looney tunes. I am thinking I have inadvertently changed settings or something but cannot think where to start.

Has anyone else come accross this problem?

Thanks for any help,

Phil.

Check your foreground/background colours. If your background is black and the foreground is white, the eraser and brush tools will behave as you said.

When you are using the brush, you are painting the foreground color. If the foreground color is white, you expand the selection area. If the foreground color is black, you contract the selection area. If the foreground color is a shade of gray, you partially select the area.

You have changed your foreground and background colors in Quick Mask mode, that’s all.
