Drawing Krita offers traditional as well as advanced painting methods using creative tools, which support both desktop and graphic tablets. It comes with several tools for rendering, blending, color mixing, transformation, smoothing, laying, mirror effects, etc. It can also manipulate photos and supports HDR images. Krita art program comes with a standard modern interface design which has the following look. On the left side, there is a toolbar which has something in common with popular Photoshop tools while on the right side, there is a panel with layers, line brushes and tool settings. All pictures created by you will be displayed in the top part of the tab which resembles a browser a bit. Over the tabs, there are two (as for me) key indicators using which you can regulate brush size and opacity. In case you have a graphics tablet, you can adjust pressure as well. There are also hotkeys which you can customize.

When painting, you can work with colors as well as textures. The good thing is that Krita is installed with 2 layers by default. One layer is white and the other one is a new layer for your next picture. There is a rather great section of settings in which brushes become more flexible than in Photoshop. The variety of settings is really impressive – ranging from form and color, ending with sharpness as well as smoothness.
