Quick mask

[Britsdad]

Hiya guys,
Here's another one for you...When I go into "quick mask" mode I can add to the mask by painting in black, but for some reason I can't take away from it by painting with white. It used to work, and I cannot recall changeing anything in the preferences of late.
Now, when I choose the eraser tool it works properly but of course the wrong way round (white adds, black removes)
Have I managed to change a setting for the brush somehow? Any help please?

is your brush setting in "normal" mode? you might have it in overlay.

KR1156....That was quick! You are almost spot on there I had it in "darken" changed it to "normal" and Hay-presto it works.......you're a star
Such a small thing causeing all that trouble, I'll remember that for next time.
Cheers.....John

John...

Here's a couple QM tricks if you've not seen them before:
* Filter > Other > Minimum
* Filter > Other > Maximum

These filters will expand or contract the selection area by the number of pixels specified in the filter dialog.

Blur > Gaussian Blur will "feather" the selection.

These are an alternative to Select > Feather and Select > Modify [Expand, Contract]. The benefit is being able to "see" the result of the change as you tweak the setting values.

I always wondered what use those minimum/maximum filters were for... thanks for the tip
