Krita
INCAZELO:
Krita is a FREE and open source painting tool designed for concept artists, illustrators, matte and texture artists, and the VFX industry. Krita has been in development for over 10 years and has had an explosion in growth recently. It offers many common and innovative features to help the amateur and professional alike. See below for some of the highlighted features.
User Interface
An intuitive user interface that stays out of your way. The dockers and panels can be moved and customized for your specific workflow. Once you have your setup, you can save it as your own workspace. You can also create your own shortcuts for commonly used tools.
Brush Stabilizers
Have a shaky hand? Add a stabilizer to your brush to smoothen it out. Krita includes 3 different ways to smooth and stabilize your brush strokes. There is even a dedicated Dynamic Brush tool where you can add drag and mass.Pop-up PaletteQuickly pick your color and brush by right-clicking on the canvas. You can also use Krita’s tagging system to swap out the available brushes that are displayed. The ring outside of the color selector contains the most recently used colors. These settings can be configured through the preferences.
Brush Engines
Customize your brushes with over 9 unique brush engines. Each engine has a large amount of settings to customize your brush. Each brush engine is made to satisfy a specific need such as the Color Smudge engine, Shape engine, Particle engine, and even a filter engine. Once you are done creating your brushes, you can save them and organize them with Krita’s unique tagging.
Wrap-around mode
It is easy to create seamless textures and patterns now. Press the ‘W’ key while painting to toggle wrap-around mode. The image will make references of itself along the x and y axis. Continue painting and watch all of the references update instantly. No more clunky offsetting to see how your image repeats itself.
Resource Manager
Import brush and texture packs from other artists to expand your tool set. If you create some brushes that you love, share them with the world by creating your own bundles. Check out the brush packs that are available in the Resource area.
Although it is best designed for digital drawing, from many years of testing I can say that it is the best replacement for Photoshop for Linux. The fact that it supports non-destructive editing means that you can “destruct” an image as many times as you want without reducing its quality. Plus it allows for easily adding of layer effects which is very useful for web-design. You can copy paste images from the web, you can manipulate them any way you want, and the fact that it supports vector layering it means that you can combine normal image editing with vector editing in the same project.
