Krita 2.8 Released
JDG1980 writes "Krita, an open-source graphics editor, has been around since 2005, but no stable version existed for Windows users — until today. With the release of Krita 2.8, full and stable support for Windows users is finally a reality, thanks to input from KO GmbH and Intel. Krita brings some things to the table that GIMP does not: 16 bit per channel color support, adjustment layers, and a name that won't set off red flags at HR, just to list a few. You can download the Windows version here. Might be worth looking into, if you're tired of the lack of progress on GIMP and don't want to pay monthly "cloud" fees to Adobe."
Krita is the best and most powerful open source program for digital painting. Period.It has a amazing brush engine. You can use other tool as your brush (for example, clone mode). In this version, the brushes were created by artist like Timothée Giet, Ramon Miranda, Wolthera or David Revoy. Also has handy tools for painters like rotate canvas, perspective tools, symetric and mirror modes, pseudo infinite canvas, stabilizer helpers, a lot of palette dokers, and now includes some tools for games developers like Clone Array or Wrap Around mode to create tiles. If you didn't give a try before to Krita, this is the moment. It's one of the best pieces of open source progams out there.
