The flatpak build is new and has known limitations, though it will likely provide faster updates, following GIMP releases closely.
Therefore choose your installation medium according to your needs.
The flatpak link above should open your software installer and prompt you to install GIMP. Yet it may not work out-of-the-box on some platforms since the flatpak technology is new. If that is the case, ensure flatpak is installed and if clicking the link still does not prompt to install GIMP, then manually install by command line:
Once installed, it will be made available exactly the same way as other applications (menus, desktop overview, or any specific application launch process used by your desktop).
If this is not the case, we suggest to report a bug to your desktop or distribution asking for proper support of flatpak. In the meantime, you can still run it by command line (not as the recommended method, only a workaround):
This installation will also provide regular update. You don't have to come back on this page and install again (it will not work!) when a new version of GIMP is released. Instead if your distribution and/or desktop has a good support for flatpak, it should propose to perform updates.
Once again, if your distribution does not have proper support, you can always fall back to using the following command line:
Third party packages are not officially supported by the GIMP project. Therefore you should report issues to the packagers first, before reporting to the GIMP team. We only list some of these package systems here because they are widely used FLOSS projects, though we won't list projects providing very outdated versions.
An easy way to compile and install GIMP and other great Free software on your Mac is by using Macports. The installer allows you to choose from a large directory of packages. To install gimp using Macports, you simply do sudo port install gimp once you have Macports installed.
Homebrew is similar to Macports and provides packages (aka formulas) to install, either by compiling them from source or by using pre-made binaries. There are indications that there is now a formula for GIMP, installable with: brew tap homebrew/cask && brew install --cask gimp.
Fink is a package repository that offer mostly precompiled binaries. It provides the apt-get command known to e.g. Debian and Ubuntu users, and installing GIMP is as easy as sudo apt-get install gimp once you have installed the Fink installer.
If there's no binary package, then fink install gimp will compile GIMP from source.
Disclaimer: we haven't been able to determine if it is possible to install or build recent GIMP from Fink. Last we checked, GIMP 2.6.12 appears to be the most recent GIMP package that is offered there.
GIMP on the Microsoft Store is the same as the direct link installer. If you wish to install through the store, we recommend using the provided store link as our team cannot vouch for third-party packages of our code.
I learned to embroider when I was a kid, when everyone was really into cross stitch (remember the '80s?). Eventually, I migrated to surface embroidery, teaching myself with whatever I could get my hands on...read more
Silk gimp works very well couched, just like smooth passing thread in goldwork. But it can also be used for other types of stitching, such as detached filling stitches (detached buttonhole, trellis stitch, and the like) and other loop-type, lacing stitches (such as Pekinese stitch, interlaced herringbone stitch, laced backstitch, and the like).
2. Use a needle that is larger than you think you need. You really want to open up the fabric for the gimp to pass through easily. Chenille needles work ok, but I preferred using a Japanese hand made needle (#13), because the smooth round eye is less likely to mar the thread where it passes through the eye.
Because trellis work passes through the fabric very little, I stitched down a grid of interlocking trellis, just to see how it would look with the silk gimp. I like it a lot, and plan to play further with laid threads and laid thread fillings, as well as woven fillings.
So, I've been using this color correction method for a while, and I am in the process of writing up a tutorial on my blog about it (complete with a walkthrough video).
[edit]
The blog post is up!
I've finally just sucked it up and pushed a blog post out with a Wink video of the process.
Getting Around in GIMP - Color Correction
I had already recorded the video, and as such was too lazy to go back and re-record it using sample points. Let me know what you think!
[/edit]
In looking quickly through the group discussions, I couldn't find something that adequately addressed what I do (at least how I approach it). So I thought I might share with you guys (and get some feedback on one of the steps).
I basically approach color correction using these steps:
1. With an image open that I want to adjust, I will invoke Colors -> Threshold
2. Drag the black point slider all the way to the right (the entire image will appear black usually), then slowly pull it back left until a clearly defined white area shows up.
3. This area is the brightest pixels for your image, so zoom in on them, and then cancel the threshold (remember where the pixels were).
4. Open Colors -> Levels and choose the white point picker (eyedrop), then choose where your brightest pixels were from your threshold adjustment (you can sample average, and modify radius to suite).
5. Hit OK.
6. Open Colors -> Threshold again.
7. This time, drag the black point slider all the way left (the entire layer will turn white).
8. Now grab the white point slider, and drag it all the way left as well (image will be mostly all black).
9. Slowly drag white point slider to the right until you get some white pixels showing up again. These will be the darkest pixels in your image. Zoom in on them and remember where they were.
10. Open up Colors -> Levels again, and this time choose the black point picker, and pick where the darkest pixels were in your image to set the black point.
And this is the magic portion that I am wondering what some of you other GIMP gurus might be able to comment on:
11. To find the middle grey tone to set your color balance to...
12. Create a new layer above your current layer, and fill it with middle grey RGB(128, 128, 128).
13. Set the layer blend mode to difference.
14. Create a new layer from visible.
15. On the new layer from visible, invoke Colors -> Threshold again.
16. Pull the black point slider all the way left, and pull the white point slider all the way left as well (the entire layer should be black).
17. Pull the white point slider slowly to the right until some white pixels appear. These white pixels are the pixels closest to middle grey.
18. As before, note where those pixels are, cancel the threshold adjustment and hide the difference layer.
19. Activate the layer you are adjusting the color on, open Colors -> Levels again and this time choose the middle grey color picker, and pick on the pixels noted in the previous steps.
Voila!
The theory is that a middle gray difference layer, when run through threshold, will expose pixels that are closest to true middle gray to key off for color correction.
Any thoughts? I'll have a link to a blog post w/ video of me performing these step-by-step shortly, but was interested in any feedback as well.
[edit]
BTW, I've found a thread on the photoshop support group that describes a similar process

It would help me to understand what you;re doing if you would explain what each step is intended to achieve, and how all the steps in sum add together to achieve the result you want.

Basically, I want to use the Colors -> Levels to adjust the white point, black point, and middle gray points in my image.
I use Threshold to quickly identify where the brightest pixels are in the image (to set the white point to), and the same for the darkest pixels in the image (to set the black point).
The 50% gray difference layer is interesting. If I want to use the eyedropper in Levels to set the middle gray, I need to find a close middle gray color in my photo. If I know where there is one, this is easy. But what if I don't?
I can fill a layer with middle gray above my color adjusting layer. If I set the layer blend mode of the gray layer to "Difference", I will get an interesting result. I "Copy Visible" this result so I can run a threshold against it again.
This time in the threshold window, all of my values will show to the left of middle (this is because the far left of that graph is "middle gray", and all values to either side of it appear to the right of it.
Now if I use threshold to filter pixels on this layer based on the left most point, the first white pixels that appear while dragging the white slider should be the ones closest to "middle gray", which is where I want to pick in my color levels dialog.
Does that help clear up the steps? I have a short video coming of my actually doing this. I'll post it soon.

A very interesting concept to color balance.
I generally like to slightly bump up contrast and saturation in my images. It seems to me that doing this after your color balancing method might alter the color balance. Should contrast and saturation be adjusted first?
