Krita is a free and open-source raster graphics editor designed primarily for digital painting and animation purposes. It features OpenGL-accelerated canvas, colour management support, an advanced brush engine, non-destructive layers and masks (similar to Adobe Photoshop), group-based layer management, vector artwork support and switchable customisation profiles. It is written in Qt and runs on Windows and Unix-like OSes (including Linux and macOS).
Paint.NET is image and photo editing software for PCs that run Windows. It features an intuitive and innovative user interface with support for layers, unlimited undo, special effects, and a wide variety of useful and powerful tools. An active and growing online community provides friendly help, tutorials, and plugins.
Every feature and user interface element was designed to be immediately intuitive and quickly learnable without assistance. In order to handle multiple images easily, Paint.NET uses a tabbed document interface.
Usually only found on expensive or complicated professional software, layers form the basis for a rich image composition experience. You may think of them as a stack of transparency slides that, when viewed together at the same time, form one image.
Many special effects are included for enhancing and perfecting your images. Everything from blurring, sharpening, red-eye removal, distortion, noise, and embossing are included. Also included is our unique 3D Rotate/Zoom effect that makes it very easy to add perspective and tilting.
Paint.NET includes simple tools for drawing shapes, including an easy-to-use curve tool for drawing splines or Bezier curves. The Gradient tool, new for 3.0, has been cited as an innovative improvement over similar tools provided by other software. The facilities for creating and working with selections is powerful, yet still simple enough to be picked up quickly. Other powerful tools include the Magic Wand for selecting regions of similar color, and the Clone Stamp for copying or erasing portions of an image. There is also a simple text editor, a tool for zooming, and a Recolor tool.

For other uses, it is licensed as commercial software.
It is now available for Windows, Windows Mobile and Pocket PC but was previously available for Unix-like systems as well.
Darktable is an open source photography workflow application and raw developer. A virtual lighttable and darkroom for photographers. It manages your digital negatives in a database, lets you view them through a zoomable lighttable and enables you to develop raw images and enhance them.
Raw is the unprocessed capture straight from the camera’s sensor to the memory card, nothing has been altered. There are multiple alternatives in the open source world for raw development (ufraw, dcraw, rawtherapee) but darktable tries to fill the gap between the excellent existing free raw converters and image management tools (such as e.g. ufraw, rawstudio, f-spot, digikam, shotwell). It focuses on the workflow to make it easier for the photographer to quickly handle the thousands of images a day of shooting can produce. It’s also one of the very few FOSS projects able to do tethered shooting.
The user interface is built around efficient caching of image metadata and mipmaps, all stored in a database. The main focus lies on user interaction, both in terms of a smooth interface design as well as processing speed. High quality output is also one of our goals.
All editing is fully non-destructive and only operates on cached image buffers for display. The full image is only converted during export. Raw image loading is done using rawspeed, high-dynamic range and standard image formats such as jpeg are also supported. The core operates completely on floating point values, so darktable can not only be used for photography but also for scientifically acquired images or output of renderers (high dynamic range).
