brush feathering radius
I haven't had to use the GIMP in some time. Forgive me if this has been asked before, I tried searching the forums but it's been so long since I've needed to use the GIMP that it's almost useless for my question.

I don't remember which version of the GIMP I used to use (maybe 2.4.x?) but it was definitely before single window mode. When you chose a brush it used to pop up a window with the brush properties and it had a slider on how much feathering you wanted and with my current version (2.8.0) I don't get that window anymore. Everything's completely foreign to me on this version and all I want to do is adjust the feathering radius on a brush.

For a little background on what I'm working on, I want to add a layer (I know how to do that), set the transparancy (I know how to do that) and use a brush to manipulate via that new overlay the colors on a section of the photograph. The default feathering on existing brushes is absolutely unacceptable for what I need and I can't figure out how to do the very simple task of adjusting the feathering radius on a brush.

I'm in single window mode because all of the ways I was used to bringing up tool windows seem to be gone. I feel like a complete n00b even though I've been using the GIMP since Mandrake 8, I think. (Oh goodness that was so long ago.)

I'm completely at a loss here.

Also, I'm very sorry to say that this is a project for work and they're using GIMP for Windows 2.8.0.

Any help would be greatly appreciated. I'm trying to keep them away from buying any more proprietary software.

RE: brush feathering radius
Are you thinking of the brush editor, where you can change the 'fuzziness' ie hardness of a brush.
Pulled the brushes tab off here and brought up the editor dialog. The icon next to it is for editing an existing brush.

You can edit then save a local brush (pre-mades are write protected unless you go into preferences) and refresh with the green circular arrow.

There are some premade brushes already with 25 / 50 /... hardness. ( that you do not like ) Wink
In use the brush size is now controlled by a slider in the tool options. Depending on where you have the mouse the rate of change varies.
Sometimes easier just to enter a size from the keyboard, also the square brackets ][ adjust in pixel increments.

RE: brush feathering radius
So... I have to create a new brush.
Wow... After hours of trying this I have to say I'm either very stupid or very unsatisfied with the GIMP now.

Hardness seems to be closest setting to what I'm used to being called feather radius but it doesn't seem to work right at all. The only thing is, it doesn't seem to do what it's supposed to do. I need a large brush that is, how do I say this... "more fuzzy around the edges" The only the settings in Edit Brush seem to be doing is making the brush smaller.

I can see a bit of difference with the hardness, but when I get hardness about where I want it the brush is so small that it would take me just countless hours and hours of work to get what I need. It's almost like it would be easier to create 100 layers of varying opacity and edit this image pixel by pixel. I've tried brush radius up to max and still the brush ends up so tiny by the time I get the Hardness where I want it.

Unbelievable. I feel like I've got to be missing something because I feel like a complete idiot and I want to throw my computer out the window. I don't remember it being this difficult before. I've built linux from scratch, done my monitor configuration using a terminal text editor, and compiled my own kernel and none of it was ever as frustrating as this has been so far. I've been at this for what... 8 hours now and feel like I've made no progress whatsoever.

Well, thank you very much for your help, I do very much appreciate the reply.

Can you recreate what you would like the brush to look like or link to a simliar brush you found that you want it to look like?

My 2 cents are, on the brush toolbox settinges there is also an []incremental setting, try toggling that on.
What incremental does is if you have the brush on medium hardness, when you paint, it will progressively get darker over time.

Also try these settings on a new brush (be sure to name your title your new custom brush, don't leave it "Untitled" )
Radius: 76.7 (you can then adjust how big the brush is on the Toolbox options (scale)
Ignore the aspect ratio unless it makes a difference to you.)
Hardness: .80

Then after you create the brush, make sure you name it in the Brush Editor, then close the editor and pick your made brush from the "Brush" list, you can now freely edit it & see the changes instantly.

PROTIP: before you change the radius, make sure the hardness is set at 1.00, the preview for the Radius maxes out around 60.5, you can further increase the size with the "size" setting under the Toolbox Options.

Here are two possible setting outcomes (one I mentioned above)

I am guessing...never will be satisfied. Photoshop is only $20 - $30 a month.

You can make a brush very quickly from scratch exactly as you require. Make a greyscale, transparent canvas and export the result to ./gimp-2.8/brushes. That will allow the brush to take on colour.

This has a lot of "feather" 45 pix on a radius of 50 pix, so obviously the 'core' is smaller, same as the brush editor. Might be possible to get the required result using a radial gradient or some over-painting.
but:
A comparison with the brush editor (the black ones) showing varying hardness values does not show any real difference. Remember that the brush opacity and size can also be varied.

I also used Gimp from version 2.2 (windows - looking at my archive, I actually have a Gimp 1.2.5 from 2003 but do not recall using it) through to 2.8.6 (PClinuxOS) and I can not remember a big very fuzzy brush in earlier versions.

RE: brush feathering radius
iForStyle007 , rich2005, thank you for the extra suggestions. Between the two later posts I'm having greater success. Sorry I sounded a little cruddy on my last post. I was frustrated after spending all that time. I'll continue to try different things with the ideas you posted and thank both of you very much. I'm very grateful for your replies.

No worries, gimp has somewhat of a learning curve, so does photoshop.
I found myself frustrated with the places in the open... dialogue box, I had accidentally dragged a file into the bottom half of the "places" column, and when I clicked on the file, it crashed the whole program. Deleted the file from its original location (after saving it to a new location/as a new name) & boom! fixed ^_^

Good to see that its working better for you now, just have patience, good luck! ^_^
