Krita's an open-source painting tool designed for illustrators and concept artists, and a perfect free alternative to Photoshop CC. 2015 was a big year for this free graphic design software, with a crowdfunding campaign helping to fund key improvements including performance boosts and animation support.
Since then, the software's growth has spiked, and so the timing of Digital Painting With Krita 2.9 couldn't be better. It's essentially a 226-page instruction manual for the latest version of Krita. But unlike most software manuals, both the layout and writing style are anything but boring. This colourful guide is packed with illustrations from the author and contributing artists, making it a delight to peruse and learn from.
