help with digital water color: blending

[Jinbrown]

Hi,

I just did a quick demo, certainly not a pains-taking blending job, but enough to show you it can be done and there's no white introduced while blending these two colors:

Top shows the colors before blending; bottom after blending.

Before starting, I reset my Brush Tracking (Preferences > Brush Tracking). You'll need to do this, then test to find what speed and pressure you apply on the Brush Tracking scratch pad will work best for blending DWC paint. After you find the best settings, take note of them as you may want to set them up again in the future. (Or do a screen print of the Brush Tracking dialog box, then save it as a JPG with an appropriate file name, in the folder where you're saving your Digital Watercolor painting files.)

I used the DWC's New Simple Water with its default settings.

For the DWC's Pure Water Brush:

Since it has Wet Fringe set to 85% and the New Simple Water has it set to 10%, I lowered Wet Fringe to 10% to match the New Simple Water setting.
Adjusted the brush Size several times, as needed.
Adjusted Opacity down to 10% and up as far as 15% while blending, depending on which seemed to work best. Anything over 15% didn't work well for me.
Try this to see if it helps. Again, my quick demo is not a great example of blending and I'm sure you can do better with a little more time.

thanks a lot for the detailed explaination, but i've just found a brush from this thread http://forums.cgsociety.org/showthread.php?f=112&t=297940 by Robert which is the Rob's basic to be most closely resembles exactly what I needed (bows to him) I really had no idea what category is it since i don't know anything about how to customly build a brush in painter. but his brush just worked... like charm... it really resembles the strokes of DWC new simple water and it actually blending itself easily only by playing with pen pressure alone... not just that... it also sutracts value in a way when it's lightly pressed.. and does very nice blending at the same time. and best of all... it can be interacted by all other tools... i can use regular blender to blend it... I really wished that there is such a brush can be build in photoshop(even thought it's a little simular to pen opacity flow brush... but i can't get it to be this perfect...)

Hi,

Haven't read the linked thread yet but I'm guessing it's Rob Chang's brush and it's one he set to both paint and blend by adjusting Resaturation lower and bleed higher than the default settings. That works very well for a lot of brush variants that aren't in the Digital Watercolor category or Watercolor category.

Glad you found something that works for you, and your heart wasn't set on using Digital Watercolor after all.

Cheers!

hehe, thanks! btw I found that brush very simular to the way some oil pastel reacts. O.O

[Jinbrown]

Check/compare the Resat and Bleed slider settings for the Oil Pastels variants you mention with the Rob's brush you like and I think you'll find they're similar in that:

Resat is set low
Bleed is set high (or higher than Resat)

Then take a look at the Resat and Bleed slider settings for many of the the Blenders' variants. If you don't see them on the Property Bar, look in the Brush Controls' Well palette.

Then you'll probably understand what makes brush variants capable of either painting and blending or just blend existing color.
