ArtRage offers a powerful but much more simpler interface than Corel Painter X and is available for Mac or Windows. To maintain application consistencies, the manufacturer deviates from GUI standards of both operating systems. For example Cut, Copy, or Paste on the Macintosh should be under the Edit menu. About this Program is supposed to be under the Application menu along with the Preferences.
With support for layers, ArtRage offers a variety of drawing tools like Oil Brush, Pencil, Palette Knife, Airbrush, Chalk, Glitter, Paint Roller, Paint Tube, Felt Pen, and Crayon. Basic paper, canvas backgrounds can be adjusted for texture, opacity, color and more. Import and export JPG, PNG, BMP, or PSD and saves in its native PTG format. The absence of TIFF (please don't use BMP) and lack of CMYK color space may place this as an adjunct to the Adobe mainstay rather than a replacement. However, most original digital art creation is recommended in RGB.
If you are curious about the possibilities, look at some of the tutorials on the Web site, download the tool-limited demo and draw your own conclusions. When you buy, there'll still have plenty money left over for a Wacom tablet.
