Is there any way to do this?

I love the brushes in Painter, but occasionally I just want to paint in such a way that all the colours underneath are altered in a purely mathematical way.

i.e., if I draw over the piece with black at 50%, I get just that. The brush doesn't overwrite itself or add more saturation than 50% on consecutive passes.

I guess you could create a layer at 50% and paint over that... but that would just be infuriating.

I struggle with the same question.

looking forward to an awnser.

Scratchboard tool variant. Features linear color add like Photoshop, but might be a little square nibbed for your tastes. Some internal stroke artifacting on lyrical lines, so it's best used in short hatching marks. Works amazing on layers. I use it mainly for detailing and color mixing when I want a straight color solution. I think it has a more expressive nature than your typical Photoshop brush and with a little practice it produces similar results. It's set up for me so feel free to screw around with the settings.

I usually use the Felt Pens for that kind of thing but I don�t know if it is what you are looking for, anyway The felt Pens gives more of a black ink stroke, I use "Felt Pens" with the "Fine Tip", temble around with it.
If you draw a big black stroke with the fine tip in opacity 36 you can add color beneath it.

Pat: Yep! I've got a similar setup in Painter 6 using a variant of the scratchboard tool. I seemed to get overwrites when changing direction during a brushstroke like you mention. Anyhoo, I need to get a hang of Photoshop 7 anyway. Do you use a mixture of both or just do your painting in Painter?

Matthew: The Felt Pens are great. I wish it didn't go totally to black, but otherwise it's a great tool.

I paint in Painter 99% of the time. I occasionally use Photoshop, but rarely exclusively anymore. My personal preferences lean towards a more smudge look, which is a real pain to achieve in Photoshop. If it's got heavy layers, masking or lasso-ing I'm doing it in Photoshop. I also color correct and mode change in Photoshop. Painter is just weaker in those categories. I'll also use it when a project demands a resolution that's outrageous, which has happened. Everything else I handle in Painter.

I've been developing this weird moral problem with overpainting photos to develop texture, which is almost standard practice these days in Photoshop. Even though I shot many of the photos myself, it just wasn't sitting well with the painter in me because I was thinking of my work in terms of collage as much as paint. Nothing wrong with that, except that's not what I want. Maybe it's artistic snobbery, but I don't want to rely on photos. Since then I've been using Painter to interactively generate my textures using custom papers and textures and I've been a lot happier. Photoshop 7 nullifies most of my objections to a large extent, but for me it's still not as strong as Painter in the custom brush arena so I'm sticking with what works for me best.
