Re: [Gimp-user] Select Feather - OR - Select Invert Feather

Hi Elwin, gimpusers:

 I can't comment for sure on the effect you describe, I think there
 might be a slight difference.  The method I use for feathering
 selections, I think, offers a bit more control, plus allows one to
 have increased feathering where indicated.

 What you do is to make your selection, then turn on quickmask, and
 then use gaussian blur on the quickmask, one or more times (and
 perhaps with different settings to sort of smooth things out). 
 This allows one to actually see how much feather you are gonna get
 before you actually make use of the selection.  Once you have a
 properly blurred quickmask, then you just convert it back to a
 selection and do whatever you want with it.

I've been playing around with your method of making a selection, and
I'm afraid I have a newbie question.  How do you blur the QuickMask?

I use the QuickMask all the time for making a selection with a fuzzy
brush. Do you simply activate the QuickMask and then
Filters  Blur  Gaussian Blur?  But doesn't this Blur the entire
image - selected and not selected?

Thanks so much.

 1a. Make a Selection and then Feather.
 - OR -
 1b. Make a Selection, Invert the Selection, and then Feather.

 Sometimes, in either case, there is an intervening Grow.

 Does the Invert of the Selection and then the Feathering (1b) produce
 different results than just Feathering the original Selection (1a)?

The feathered version of the inverted selection will of course be  
inverted compared to the feathered version of the selection, but  
otherwise identical.

I am going to retract that -- or at least qualify it. There is a  
difference if the selection mask is not boolean, that is if it was  
already feathered to some degree before being feathered.
