Over six months ago, I stopped using Adobe Photoshop and switched to the open source alternative, GIMP, for all my personal photography projects. This wasn't the impossible task that most people believe it is.
This post originally appeared on Riley Brandt's Photography Blog.
Users often claim that Photoshop is absolutely essential to their workflow. Across the internet, forum users are ridiculed for even suggesting that someone try to replace Photoshop with GIMP.

Learn the Basics of Photoshop: The Complete Guide
GIMP is one of the best online image editing services but without GIMP plugins, you can’t be able to use its advanced features. These plugins are usually written in the Python and you can install all of them within a few seconds.

This is the same for many other professionals. We've all switched to the RAW format, so we use RAW photo editors most of the time. Photoshop is often just used for final touch ups.
For the reduced role that Photoshop now plays in many photographers' workflows, GIMP is surprisingly capable. However, transitioning to GIMP can be frustrating because the keyboard shortcuts, tools, and interface are different from Photoshop's. Hopefully these setup tips can help make Photoshop users feel much more at home in GIMP.

In this tutorial, we'll be tweaking some configuration files in the GIMP's settings folder. This is in a different place on every system. So, mark down where this folder is, and keep it in mind for future steps:
Windows: C:Users[your user name].gimp-2.8
Mac OS X: ~/Library/Application Support/GIMP/2.8/ (You may have to unhide the Library folder first)

Linux: ~/.gimp-2.8
From here on out, we'll refer to this as .../.gimp-2.8, which you can just replace with the above paths. Now let's get started!
Set Up Photoshop Keyboard Shortcuts in GIMP

By simply replacing one configuration file, you can have Photoshop's keyboard shortcuts enabled in GIMP. This, by far, is the most helpful thing I did to make my transition to GIMP easier. In fact, I am almost useless in GIMP without it.

- Download the ps-menurc file from freeshell.org
- In GIMP's ....gimp-2.8 folder, rename the file 'menurc' to 'menurc-backup'
- Rename the ps-menurc file you downloaded to 'menurc' (with no .txt extension) and move it to ....gimp-2.8
- Relaunch GIMP for the changes to take effect
Note: After installing the configuration file, you may have a few shortcuts that conflict with one another, so I recommend going to Edit > Keyboard shortcuts and making sure everything is in line with this chart. I also recommend binding '[' to Decrease Brush Size More, and ']' to Increase Brush Size More to speed up brush size changes.

Install a 'Layer From Current Selection' Replacement
In Photoshop, CTRL+J can be used for more than just duplicating the current layer, it can make a new layer from the current selection. This is a really handy tool that I use very often in Photoshop. You can add the same function to GIMP's Layer menu with a plugin called Layer via Copy/Cut.
Advertisement
- Download the plugin Layer via Copy/Cut
- Install it by dragging the layer-via-copy-cut.py file to .../.gimp-2.8/plug-ins/ (and if you're on Linux, make sure the file is executable)
- With your current layer active, make a selection
- In the main menu, choose Layer > Layer via Copy
- Your selection will be copied to a new layer
Combining the 'Layer via Copy' feature with layer masks is a great way to create composite images in GIMP. The two can also be a capable (but less efficient) replacement to the patch tool in Photoshop.

Make 'Snap to Canvas Edge' the Default
Something I find really frustrating in GIMP is that by default, layers don't snap to the edge of the canvas (or the grid) when I move them. Even worse, you have to enable it every single time you open an image. Fortunately, as open source software is so customizable, this can easily be changed.
Advertisement
- Open .../.gimp-2.8/gimprc with a text editor
- At the bottom, add the two lines:
(default-snap-to-canvas yes)
(default-snap-to-grid yes)
- Save and close
Disable 'Show Layer Boundary' by Default
Advertisement
Something I never got used to in GIMP is the yellow and black dotted line that surrounds the active layer. Though it can be helpful at times, I definitely prefer to have it disabled by default.
- From the main menu, navigate to Edit > Preferences > Image Windows > Appearance
- Uncheck Show Layer Boundary under Normal Mode and also Fullscreen Mode
- Restart GIMP to for the changes to take effect
You can always temporarily turn it back on by clicking on View in the main menu and choosing Show Layer Boundary.

Make the Move Tool Function Like Photoshop's
By default, the Move Tool in GIMP is set to Pick a Layer or Guide. With this option set, it behaves a bit more like Inkscape or Illustrator because you can also move things that are not on the current layer (like the background). If you are a long time Photoshop user, this is very strange.
Advertisement
To make it function like Photoshop, you can set the default behavior to Move the Active Layer.
- Select the Move Tool for the Tool Box in the left panel
- In the Tool Options dialogue box check Move the Active Layer
- From the main menu navigate to Edit > Preferences > Tool Options > Save Tool Options Now
- Restart GIMP
Install a 'Content Aware Fill' Replacement
Advertisement
The useful 'Content Aware Fill' feature that showed up in Photoshop CS5 actually originated as a GIMP plugin called 'Resynthesizer.' It allows you to select something you want to remove from an image, and with the push of a key, it's gone without a trace.
The Heal Selection plugin (aka smart remove) is a great replacement for Content Aware Fill. To install it, just download the Resynthesizer and Heal Selection plugins and drag the necessary files to .../.gimo-2.8/plug-ins.
If you're using Linux, you can also install these and many other useful plugins via Thorsten Stettin's PPA by running:
sudo add-apt-repository ppa:otto-kesselgulasch/gimp
sudo apt-get update
sudo apt-get install gimp-plugin-registry
Advertisement
Once installed, you can make a selection, and then navigate to Filters > Enhance > Heal Selection. Voila!
Install ICC Color Profiles
Advertisement
You can download high quality, freely available ICC color profiles (like sRGB) online and use them in GIMP. Windows, Mac, and Linux users can get sRGB ICC profiles directly from the International Color Consortium. If you are running Ubuntu, or any of its derivatives like Linux Mint or elementary OS, you can get them directly from the repositories. Just search for 'icc color profiles' in your package manager. They will be copied to /usr/share/color/icc/.
For the photographers shooting in the Abode RGB color space (which has a wider color gamut than sRGB), you can download the color profiles from Adobe's website. This package also includes CMYK color profiles. You will be required to agree to Adobe's EULA. I recommend copying the files to /usr/share/color/icc/ on Linux, or another safe folder on Windows or Mac.
Once you have the color profiles on your disk, you need to let GIMP know where they are. From the main menu in GIMP, go to Edit > Preferences > Color Management. Make sure Mode of Operation is set to Color Managed Display, and select your RGB and CMYK ICC files in the drop down menus below.

Of course, your monitor has already been color calibrated, right? Nobody would be silly enough to try and color balance a photo without first calibrating their monitor... right?
Install the CMYK Conversion Plugin
Advertisement
If you want to convert an image from the RGB color space to CMYK in GIMP, you can do so with the Separate+ plugin. However, there are a couple of limitations. The Arch Linux wiki has a great write-up about the limitations (as well as how to soft-proof an image). Separate+ can do a few things:
- Separate a RGB image
- Attach ICC profiles to separated image files
- Convert from one RGB profile to another
- Soft-proof colors
You can also install it from the GIMP Plugin Registry just like we have with other plug-ins up to this point. If you're running Linux and installed the 'gimp-plugin-registry' package from the PPA I mentioned previously, you already have it.
Advertisement
To convert your image to CMYK in GIMP:
- From the main menu, navigate to Image > Separate > Separate
- This will give you a new image that looks inverted and has four separate layers
- Go to Image > Separate > Export to export your image to a .tiff file
In my experience as a professional photographer, it's actually the graphic designers and printers that who require CMYK support. Whether it's for a magazine, a newspaper or even a billboard ad, I've never had someone request a photo in the CMYK color space. In fact, they always request that the photos are in the RGB color space, then they do the conversion themselves.

Customize Your Workspace
Enable Single-Window Mode
This seems like an obvious step, but I've met several GIMP users who didn't even know it was an option. Photoshop users will feel much more at home when they have their tools, menus, panels and workspace together in one window.
Advertisement
From the main menu, simply navigate to Windows > Single-Window Mode.
Dockable Dialogues
To free up a lot of space on the left side panel, move the Tool Options dock to the bottom right panel. Then resize your left panel to something much thinner.
Advertisement
If you want GIMP to really mimic Photoshop, you can move the Layers dialogue to the bottom right panel. Personally, I've grown to like my Layers at the top and the Tool Options at the bottom.

We all know that Photoshop is the premiere application for image and graphics manipulation. It simply does everything you could possibly want, which is the reason why most professionals choose it and why your wallet has a deep hole after you buy it. But Photoshop isn’t the only image manipulation tool on the block. The leading open source alternative to Photoshop, GIMP, has plenty of power under the hood as well.
It is, however, not quite as feature complete as Photoshop on its own, so people can add functionality to GIMP by adding plugins and scripts. The range of functionality which can be added by these is practically limitless, so you’ll find plenty of things that may interest you. The library of GIMP plugins and scripts is huge, but here are my top picks for some impressive extras.
Layer Effects
Layer Effects is a script which replicates plenty of the same functionality found in Photoshop. You can recreate anything from borders to drop shadows, inner shadows, bevels, embossing, and glows. You can also use them similarly to how they’re used in Photoshop, except that you’ll find them in a different location and that each effect is applied by creating the effect on a new layer.
Therefore, you cannot go back into the settings and change the parameters – you’ll have to undo what you’ve already done or delete the layer which adds the specific effect, and then re-select the layer which you wanted to place an effect on. You should get the hang of it after a bit of messing around.
Save The Web
Save for Web is a set of GIMP plugins which allows you to become a pro at saving images which will be used on the Internet. It offers a number of different formats and quality settings, as well as a preview window. This is great because small changes in the quality sliders can significantly reduce the overall size of your image while minimally affecting the perceived quality of that image. This can be done, experimentally, with the Export tools which come with GIMP, but these tools with the preview window make it so much easier.
Photo Effects
Photo Effects is another set of plugins which let you apply different photo effects onto your images. These can be seen as image filters, but don’t expect them to be similar to those found on Instagram. While the popular photo sharing service mainly includes filters which affect the colors of your image, these effects add more – you can turn your images into cartoons, stained glass, pastel, color pencil, and much more. They’re fun to play around with to make your images a bit more complex.
Read in RAW Images
A lot of high-end professional cameras save their images as RAW data files. As the format isn’t nearly as common as .jpeg images, it takes some special software (and processing power) to load and edit these RAW images. By default, GIMP isn’t able to load these, but with the UFRAW plugin, it’s made possible. After it’s installed, it’s simply a matter of finding the image to load.
Don’t be surprised if GIMP acts a bit sluggish after loading a RAW image – the file is pretty big, after all!
Liquid Rescaling
Last but not least, may I introduce you to the Liquid Rescale plugin. Back when Photoshop CS5 was introduced, one of its biggest features was content-aware scaling of images. This was fantastic, because Photoshop was aware of what parts of the image was important, and could therefore cut out the less important parts in order to make the image smaller without squishing anything you cared about. Of course, the same applied to when you wanted to make images larger – it would know what to leave alone and what it should replicate to fill the new space.
The Liquid Rescale plugin essentially does the same thing as Photoshop’s content-aware scaling. The only difference is that you’ll have both options available in GIMP after installing the plugin – the regular scaling and the Liquid Rescaling.
Conclusion
With these five GIMP plugins, you’ll be adding quite a bit of Photoshop muscle to your GIMP configuration. Of course, there are plenty of other fantastic plugins which can be added to GIMP. You should be able to find these through a simple Google search or by checking the GIMP plugin registry. Most plugins are easy to install, as you’ll just need to copy the necessary files into either the plugins or scripts folder. Windows users can find these folders in C:Program FilesGIMP, and Linux users can find them in /home/<user>/.gimp.
