I saw an exhibit at the torpedo factory (for those local to Washington, DC area) called Pixels to Paint. An artist was using a Mac IIsi, a paint program called Oasis, and a Wacomp tablet and pen to create very painterly computer images. Two points and one question: 1 - He said that he liked the pen much better than a mouse. The pen frees his hand movements and nicely simulates the real world activity of drawing/painting; also the tablet/pen detects varying sensitivity of line. 2 - The paintings he had done (couple of self and other portraits) all had a pastel-like look to them. Question - I asked him about the pastel quality: why did the images look as if they were painted with pastel pens and what if you wanted to achieve a different color quality? His response was a rather flat, "I don't know. They do have a pastel quality to them and that's all I have to say about it." My guess is that the pastel quality is achieved because the strokes of color when applied to the image are opaque, that is a single brush of color hides what may be underneath, like a thick pastel pen stroke. With watercolor or oil paints the translucent quality of the mixed color adds an additional element to the image. It may be possible to change this visual effect by painting the image at a greater level of detail: closer to the pixel, sorta like Seurat's pointillism technique? Hamid

Color QuickDraw supports copy modes that allow a program to blend the source and destination colors instead of simply replacing the destination, if desired.
