Global Density Masking The density masking action occurs all over the selected area. With the Global density, you can pick several colors, RGB or CMYK, and create a mask on these selected areas.

Local Brush Density Masking As you move along the edge of the subject, you can sample the image with the Density Brush Picker. The selected color is used to build a mask automatically along the edge. An unlimited number of readings can be taken. Undo is possible.
AutoMask respects the natural antialiasing of the subject and the semi-transparency of the edges The mask created comes as an opacity layer or as a fourth or a fifth channel on a background image. AutoMask is the perfect tool for all the difficult silhouettes : trees, landscape, furs, animals...
AutoMask work in RGB or CMYK...directly on a layer... why spend more for another masking tools... AutoMask has it all!
