Does anyone have COREL Painter?
I don’t have the serial number, but I can tell you that even though there’s a lot of similarities between both programmes, they are intended for different uses. If you want to retouch a photograph (sharpening, softening, equalising, etc), then PhotoShop is your tool of choice. If you want to create images from scratch, which resemble the traditional media like oils or watercolours (more of what an artist would like to do), then you should choose Painter. Painter is not that good for sharpening.
