ArtRage has a variety of canvas presets and paper options, plus a wide array of brushes, pencils, crayons, rollers, and pastels. You can paint directly onto the screen or apply a glob of paint with one tool and smear it around with another. ArtRage also features a dedicated watercolour brush option, which can produce some striking effects. Experiment with the ArtRage digital canvas by smearing, blending oils and watercolour. The app is smart enough to detect the roughness of your paper so your pencils can be used for soft shading. Add layers to your work without damaging others with a range of Layer Blend Modes, import photos and convert them to oil for smearing or use as reference images, or trace over images. Once you’ve familiarised yourself with the interface, it’s easy to change brush sizes, bring up the colour picker, work with layers and blend/smudge different elements together.The main idea of Artrage is to make painting as real as possible on the iPad. You can mix paints with one another as though you were manipulating them on a real canvas. This app works with layers, and if you’re already familiar with Photoshop, you’ll feel right at home with the blend modes. Artrage also allows you to record your drawing for later viewing on the desktop.
