Blurring or blending between two colors tends to result in colors in the middle that are too dark. In Photoshop, there's a setting called "Blend RGB Colors Using Gamma" which solves this blending issue. In GIMP, I've heard some talk about a similar solution, but have not been able to find clear instructions on how to do it.

This video talks more specifically about what exactly the problem I'm looking to solve is. (The relevant bit starts at 2:17.)

I would like to create a layer which is only used for the final transparency.
The layer's RGB to be completely ignored and have no affect on the final merging of the layers.
This is used to "cutout" parts of the final image.
I already have a layer with a mask which is used for semi-transparency. I would prefer not to touch this layer.

Is it possible to set this up in Gimp?

The DIFF layer is used. The layermask is for semi-transparent areas.
I want the cutout layer to only make certain sections of the final image completely transparent.

Thanks for the help.

Hi all,
I am pretty new at GIMP and just use it occasionally. I would like to cut down a layer to a specific path I have created so that the image matches up with that layer. I have the path created, but can't figure out how to make the crop happen since it is only a partial selection. I have attached my .xcf file. 

Thanks for your help!

Now, the Free Selection Tool needs to press the Enter key to take effect, and it feels very inconvenient.
(New function: also can move nodes after connection.)

My advice is to cancel this new feature.
What do you guys think?

So uhh, my Layers disappeared, I was making a YouTube Banner and was recommended this, I was like, this shouldn't be so bad, it was... It was rage inducing, and to learn to use the darn thing I have to pay money? What? Also I had the tool box, the actual screen, and the layers, but now the layers and stuff are gone, I got the layers back, but now I don't have the background that came with Gimp... How do I get them back? And how do I color separate letters? Any video or answers for all my questions? Please and thank you.

Hi, after accidentally (silly I know) trashing my .gimp-2.8 folder I am unable to get two of my favourite and most used plugins to work together. These are Mathmap and GMIC. If I install only one or the other they work. But if I install them both only the latterly installed plugin works.

I *think* I have narrowed the problem down to the libfftw3-3.dll that both are dependent on. I've also noticed that the .dll for Mathmap is nearly twice the size as the one for GMIC.

I have had those two working together before so I'm at a loss as to why the won't do so now. Any ideas folks?

I'm on Windows by the way.

I have difficulty using the perspective tool.  After adjusting one side, I try to adjust the other side but the first one moves.  Is there a way to anchor the corners so you can go to another one without the first one moving?

Thanks in advance for any advice.

Hi, 
I practice ididology and would like to be able to superimpose the chart below over the iris of the eye on a separate layer. For this to work, I need to remove the white and make this section of the iridology chart see through, but leave the black lines intact. How do I do this in Gimp? Also, is there anyway to change the black to another colour, such as yellow, to make the black lines more visible when superimposed on an iris image. Thanks in advance !

As a very new newbie might I have some advice on removing the title from the image on a book cover and replacing it with the general background mixture of cloud and sky? 

Might there be a You Tube clip that could help? 

Many thanks.
