I don't remember how or what it was. I learned this in a photography class in college and since have forgotten it. I think it was toning or maybe split toning or perhaps it was adjusting the contract but it had to do with using the eye dropper. I think the eye dropper was for finding the darkest(shadows) and lightest(highlights) areas and using that to get the perfect black and white for that particular image. I think this was done after the channel mixer with the contract tool then you used the eye dropper to get the measurements.

How do I do this in gimp? I am using gimp development version 2.9.8. Is there a tutorial somewhere?

I have been working with Gimp and other similar shareware on my relatively new Surface Pro 4. The Surface Pen I have is an older version, since the store I bought it from was out of the newest and I wanted to get started right away. Overall it has been working fine, but just in the last day it started writing funky, starting out light and gradually darkening, this happening with each new stroke. What is odd is that it is happening across platform in other programs the same way, no matter what tool/options I've selected. It's undoubtedly due to some unintentional tinkering I've done, but I don't know where to go to fix it. I used to be able to select for a solid black stroke and actually get that, but not now. It's not good when you want to define a space with a solid outline in order to fill it with a color.

Hello, my first post/question (ever) to this group. I have been using Gimp on and off for several years but am only moderately knowledgeable about it. 

Recently my tool options became detached from my tool box (probably from some tinkering on my part), and nothing I can find or do is allowing it to "dock" again, although it plainly says below the tools that I can dock it there. Dragging it there by the top tab (as I understand suggestions I found on-line) only puts it there, floating above the tools. What miniscule step(s) am I missing?

By the way, I am working with the Surface Pro 4 and the version of the Surface Pen that has the clip (would that be the Surface Pen 3?)

Perhaps it is best to watch this video first (if you haven't seen it yet) to understand what I am having an issue with.

In Gimp 2.9 I did a test with an image in 32 bit float and linear color space, although the same problem exists in 8 bit.
I start with a simple image:
   
In a new layer using the 2.9 'normal' default layer mode, painting new colors lines has this effect:
   
This is correct.  If you look around the edges of the colors, they blend correctly.
But if I paint directly in the same layer, I get the dark outlines:
   
In other words, the new layer modes work correctly, but if colors are painted on the same layer, the colors do not blend correctly.

Anyone know what I can do to fix this?  Should I download a different color space, or is this just a hard-coded flaw?

Greetings,

Windows 10 doesn't give me the option to choose GIMP as the default program for opening jpeg's.

It gives specific programs I can choose but doesn't allow me to search in my program files to find GIMP and set it as the default. 

Any suggestions?

Thanks,

Sabia

I'm trying to make an animated .gif and it looks great when I save it uncompressed. When I compress it and save it it looks like this, with black flashing on and off once more moving parts are added.  Any idea of what is going wrong? Thanks for any help. 

EDIT: Was black when I open the .gif, transparent here.      

Hey, i'm new to Gimp so i sorry if i sound like a noob right now.

Anyways, i can't seem to move layers, and no i'm not talking about using the move tool, i'm talking about the layers on the right side, the layer WINDOW.

Is this a normal feature in Gimp? I had a feeling programs like this would allow to move your layers up and down, but i have to use the buttons instead which is kinda annoying

Thankss

(im uploading a picture, that's the window i'm talking about and i can't move layers up and down)

Gimp-Forum is no longer WIP, so it's time for a logo/banner change. Fortunately, Espermaschine had plenty of good ideas to replace our logo while keeping it clean and simple. So, which one do you prefer?

I just started seriously looking at this with the 32 bit float and linear stuff.  One person that seems to understand this is here:
https://ninedegreesbelow.com/photography...ed-editing

In particular, part C:
"GIMP 2.9 does provide a number of "unclamped" editing operations from which the clipping code in the equivalent GIMP 2.8 operation has been removed. For example, at floating point precision, the Levels upper and lower sliders, Unsharp Mask, Channel Mixer and "Colors/Desaturate/Luminance" do not clip out of gamut RGB channel values (however, Curves does clip). Also the Normal, Lightness, Chroma, and Hue blend modes do not clip out of gamut channel values."

What blows my mind is that some operations do not clip the rgb values at 100%.  In other words, I can go brighter than white and darker than black and still recover the information.  So it looks like some of the color operations allow this.

For example the exposure, HCL color changer, brightness and contrast, and a few others I think, allow me to blow out the colors and still recover them.
