Hi everyone,

I am new to GIMP and would like to use it in future instead of the expensive Adobe PS. One of my important do´s is to alter the saturation of  part of an image. I am astrophotographer and as example want/need to increase or decrease the saturation of a nebula or part of it, but not of the entire image. In PS, I choose the respective icon and see three options - darken, lighten and saturation. Inside of those, I can select shadows, midtones or lights for darken/lighten and for saturation increase/decrease.
In GIMP, I have found the options like in PS but only for lighten/darken using a brush not for saturation.

Where is this function hidden? What do I need to look for?

I have attached an image of the NGC224, the Rosetta Nebula as an example of what I do.

Thanks and greetings from Austria,

Georg

I'm running GIMP on MacOS and attempting to use some custom fonts. If I try to ctrl-f (or rather cmd-f on Mac) while in the font dialog list it will bring up the little search bar but typing won't work, and then it will disappear after 5 seconds as expected. So I can't search for fonts at all. Am I doing something wrong or is this a bug?

After generating a text, I copied it. When I tried to change the font of the copied text, it didn't work. It literally changes nothing.
Is it normal in GIMP?
If yes, what is the solution? Should I generate the text one by one instead?

Hi, I have this transparent PNG.
What I need is to make it bigger only on the width (extend the right side so I can add more text layers). 
I tried Image - Scale and increased the width but that's not what I need, since that enlarges the image and it spaces all the layers.

I only need to extend its right side so I can continue adding text layers with symbols (this file contains many symbols added via separate layers side by side so another software will read it.)
How can I make the right side bigger? (extend the right side without disturbind the rest of the image)
Gimp 2.10.30
Windows 10 x64

Thank you!

I'm either not doing something right or something isn't working right. LOL

But I'm trying to get a radial starburst effect from the center of my eye that I'm working on, and I can't seem to get the polar coordinates to work like I think they're supposed to work?

I created a radial gradient to get my lines, and then trying to apply the filter to the gradient but it isn't giving me the "star burst from center" effect if that makes sense? Or also known as speed lines...

I uploaded a screenshot. I'm not sure what I'm doing wrong?

Good morning

Thank you for every one that is helping me, I have learned quit a lot from all of you.

I just want to ask a question

I have 8 different cxf files open in Gimp.   Each one that I have color is different, so if I want to use bump map once on the first one, and then want to repeat "bump map" on the others, then it will not work on the others as the color is different, how can I get it to work without to change to the name every time, is this possible
Here is a ample, I have only 2 open, so I must every time go and select the cxf file and the name to use bump map.

Out of curiosity, does anyone have a good tutorial on making a realistic eye? Like a dragon/animal eye?

Tutorials I have found to do a dragon eye seem to be old and I can't follow them because steps they're being told to do can't seem to figure it out in gimp to try and follow along...

Any help would be appreciated!

Thanks!!

   
I'm trying to make the cut lines on this stone sample a bit more prominent. I tried levels, brightness-Contrast, Erode, and Cartoon and all don't work.

Any ideas?

I develop realtime virtual fish. I use GIMP to add transparency, etc. Here is a problem I never can do well. Look at the low res image of the tail. The end of the tail is semi-transparent. You will notice the tip it is green but really that is the background showing through. I want to remove the green without hurting the ribs of the tail which are slightly darker. 
If I use eraser with less opacity it works but the ribs are lightened and it is just lighter green. I also tried fizzy select but that takes all of it away. I want to remove the green so fish tail is semi-transparent. Is there a way with GIMP to do this?
