Emulating backwashes as texture in Corel Painter?

[Mu]

Hi,

very nice questions... I like it when I get new ideas by someone who asks for things...

For the plastic wrap technique I looked for photos of glass cracks on flickr (it has a creative commons search if you need to publish the result!)

found this one:

This i added as a layer in my watercolor painting and changed its saturation (to zero) and increased contrast and brightness... then I played around with various layer modes and opacties.

I think with better suited photos and more time (:D ) this approach could do the job.

EDIT: oops, hang on, I think I posted a wrong snapshot, dang!
Will post another one soon...

the actual backwashes I find harder to do:

This is done with a variant of which the direct translation would be diffuse eraser, the second eraser variant in the list.

Things to note:

- The higher the grain feature of the eraser variant the more likely you are to get dark edges, bordering on black

- the marks on the right hand side are subtler than the ones on the left. That is due to the colour of the base wash as the one on the right is within the safe area for colour buildup which means if you choose colours which are both light and saturated enough they won't build up to black. On the left the colours built up to dark tones rather quickly and if you use the eraser tool on these areas the running particles sum up to pure black even quicker which results in visible edges.

Another idea I did not test is:

- create a background wash with other variants from other categories (airbrush, chalk, doesn't matter really)
- then, lift the whole thing to a watercolor layer!
- work with the eraser on that layer

Maybe I will test that and post an example.
Nice tutorial site btw.

I would love to be able to replicate that in painter too. But so far in my experience it is best to go do that traditionally and just scan it in. The painter ones look to grainy and digital. Some things are still easier to do traditionally :D

[Mu]

somewhere, sometime, I don't remember where when and how I saw a demo video of a watercolor simulation by some other company or scientific project which had awesome flat washes.

Painter's watercolor machine is in my opinion the best out there to be had for money at the time being, but it's far from making someone happy who loves to work with watercolor IRL and wants a digital equivalent.

Thank you very much for your replies, Mu! I appreciate them. :) And thank you, Hecartha, for the link to MoXi! The watercolor results for the MoXi software are gorgeous. Those results are exactly what I'm hoping and trying to emulate in Painter.

If Painter ever includes such a watercolor engine in a future version, I'll be the first to buy it!

[Mu]

yes Hecartha, that's the one!

[davidgoerndt]

Finally, someone who can simulate real watercolor effects. Painter needs to seriously look at this technology. Watercolor is the one thing about Painter I've never liked, way too slow and too grainy.

[Mu]

I gotta say that driven by this discussion I took a deeper look at the watercolor engine again and I got some nice washes going... for my taste at least. Maybe I will post some of them later and hopefully some people join in so we can make the most of what we have at the time being?

[CybrGfx]

Me too!
I'm finding it's all in how you make adjustments in the Brush Palette.
I'm not satisfied, yet, but definitely enjoying the Watercolor brushes more than I have in awhile!

Thanks for mentioning MoXi, Hecartha.
I'm not sure about Corel, but I'll join Microsoft the coming Sept. I'll be working on digital painting there. I hope to bring the technology to the users soon.

Hi Nelson
So you have been hired by Microsoft hehe, good to have news from you :)

...Microsoft...digital painting...mmh, perhaps Microsoft will give some news soon about their product Acrylic. Anyway, I wish we could test soon a product (yours?) which gives us a 3d brush with a so realistic effect.

I did this in Painter 6 using custom watercolor brushes, I find the results convincing enough, you can also make watercoloring with Photoshop using brushes and layer method/textures but in here like I said I only used Painter's digital watercolors and a custom paper texture:

looking sweet, workbench!

[workbench]

Thanks Mu, what I want to emulate now is that watercolor effect when the water penetrates the paper's fibers and makes that hair line effect around the watercolor dashes, I made a test brush dab, it's only a start, my idea is to do a brush that can do it all but that's probably too much to ask.

[Mu]

I think for that specific purpose you should check out the watercolor section again as it has a parameter for that behaviour which you could try to tweak...

[workbench]

And what parameter would that be? Either way this is for emulating watercolors with the Digital Watercolors not with the Watercolor engine as this brush engine is not in Painter 6.1.

[Mu]

oh, i was talking about painter IX.5 which additionally features a totally redesigned watercolor category on its own layer type...
