GIMP is one of the best open source photo editors, which is a free Photoshop alternative. It can be used on Linux and Windows. It offers tools for color correction, image retouching, text and layers work. GIMP photo editor is a completely free desktop software, which has an interface and tools similar to Photoshop. It comes with quality Photoshop-like brushes, which ensures fast and easy work with masks and layers. The most significant disadvantage is that you can’t use GIMP on Mac OS and is slower than Photoshop and Lightroom.

RawTherapee is a photo editor designed for photo managing and basic image editing. This is an open source photo editing app with weaker functions and tools similar to Adobe Photoshop and Lightroom. Unlike other photo editing apps, it supports RAW files. There are many tools for color correction, reducing noise, rotating, adjusting exposure, shadows and light, regulating tone settings, vignetting, process EXIF-data, cropping, adjusting white balance, etc. There is a batch mode if you need to enhance many pictures.

DigiKam is a powerful photo manager, organizer and image editor, created for Linux, but also available for Windows and Mac. You can import images in various ways, organize them into albums, view and search in your collection by location, time, tags, and people. You can use this open source photo editor to experiment with different tools: create panoramas and calendars, then export selected images, share them online. DigiKam allows you not only to find images by name or tag: the search option helps you find images that are similar to others. Although the program is designed to manage your images more than to retouch them, in some cases, it has more useful functions than the specialized programs.
Paint.Net is a raster graphics editor for Windows. It has a very simple interface with logically arranged tools. The pleasant feature is that you don’t need a powerful PC configuration to use this open source image editor.
Paint.Net is a free graphics editor from Microsoft, designed for Windows platform. Keep in mind that Paint and Paint.Net are quite different programs that have different tools and functions, so do not mix them up. Paint.Net has a great number of drawing tools for basic image retouching, using quality brushes to eliminate minor defects, for example, pimples or unnecessary photo elements. In general, Paint.Net is a universal photo editor for beginning photographers or amateurs who do need the software with basic photo enhancement functions. The interface looks a little bit outdated.
Pixen is a simple and convenient open source photo editor for beginners. It is one of the best alternatives to Paint.Net, with almost the same set of tools with an emphasis on drawing. Pixen is a free image editor. Actually, this photo editing software doesn’t have such function as the GIMP photo editing app. You can use Pixen to perform basic image retouching, adjust shadows, exposure, add text, etc. What I did not like about the editor is its working speed and the lack of a 16-bit color channel.
Alternatives: Adobe Illustrator
Platforms: Windows/Mac OS/Linux
Inkscape is an open source photo editor for vector illustrations similar to Adobe Illustrator. Vector graphics is not based on a grid of pixels, like raster graphics used in GIMP and Photoshop. Instead, vector graphics consist of lines and polygons arranged in a shape. Inkscape is a free vector graphics editor to create both artistic and technical illustrations. People often use this free photo editing software to design logos and banners and generally do any tasks related to vector graphics. You can scale and visualize them with different resolutions without quality loss. Inkscape supports Scalable Vector Graphics standard, as well as a complete set of tools for converting, complex tasks and high resolution rendering. The evident disadvantage is a small number of tools for image color correction.
Krita is a powerful graphics editor, a drawing software, and an app for basic image retouching. It has a very pleasant and user-friendly interface, supports both raster and vector images. Krita has a particularly rich set of drawing tools that imitate color mixing and brush pressure, especially suitable for educative illustrations. In general, Krita is something in between GIMP online editor and Paint.Net.
Darktable is a free open source image editor with a powerful RAW files converter, tools and features similar to Lightroom. This is an ideal variant for color correction and work with dozens of photos. I think that this software is suitable only for amateur photographers.
LightZone is a free photo editing software to manage and edit RAW images. Using this open source photo editor you can easily improve photos, eliminate defects, perform basic color correction, adjust white balance, blur some areas, increase sharpness, remove traces of dust on the lens, reduce noise, which often appears when shooting with a high sensitivity rate. Instead of using layers as other photo editors do, LightZone prompts the user to create a stack of the necessary tools (chain/set of tools). While processing photos, you can rearrange, reconfigure, activate or delete a separate tool in the set.
Shotwell is the software to organize photo and video catalogs. This open source photo editor has a very simple interface and tools for basic image retouching. Shotwell is used for all kinds of platforms. The functions are designed to manage a collection of photos. Shotwell provides convenient method to catalog and navigate through the collection of images, features grouping by time and tags, provides tools for import and new photos conversion, supports basic image processing operations: rotation, red eye removal, exposure adjustment, color optimization, includes tools to publish edited photos on social networks such as Facebook, Flickr and Picasa. The disadvantage is the weak functionality, so Shotwell can’t fully replace any other program on this list.
