iPad: Pixelmator is one of the most powerful image editing tools on the iPad. Today it gets an update with a few new features. Chief among them is a new watercolour painting tool.
The new watercolor brushes allow you to easily blend colours together and create soft gradients. You can see it in action in the video above.
Alongside that, the update also includes a better colour picker, RAW compatibility, and improvement compatibility for Photoshop image masks. Thankfully, you can also now scale images proportionally, which was a weird omission from the first version of the app.
