aquarell

Beitragvon mu » Mi Sep 14, 2005 11:40 pm

Hi again,

this is my redition of aquarell-colours. It's not exactly what I want it to look like. Also, colourmixing (in german: anlösung) should have gotten a higher value in order to make the colours blend somewhat automatically at the broders.

Before I forget it: Do not consider this an addition for the sake of the pic itself - and errm hannz, actually I would like to do a caricature of you, but this was not my attempt at it. But once it was done I must say there is a little something of you in there, isn't it?

Anyway: take acrylics, an elliptical dab (can be found in the presets), switch on the outline-option, turn the ellipse (there's an angle value for that) and make it "slide" or digress your strokes by what is called in german "verwackeln". I think it's jitter in english? Argh... really looking forward to sharing brushes the easy way.

I did something to acrylics, too. But that's something for another day.

A good start again, mu! :)

Alas, I do see room for improvement, anyway: the brush is still too present to perfectly imitate aquarels. If you do wet-in-wet paintaing in aquarels, the shape of the brush is almost invisible, there's just smooth fading of the color. I don't know if it is possible at all to mimic that effect, since you have a wealth of control over the real-life brush (wet/dry paper and all stages between, more or less tilted brush, drying speed of the paint and so on).

yea, exactly. IIRC, Painter solves the problem by handling the strokes *after* they're done, i.e. you paint a stroke and after release it gets smudged and the edges run away into the paper.

I don't know wether Boris is going for the extra efforts of adding this to artweaver - i guess it must be loads of work.

I once saw a PS tutorial on creating aquarell brushes somewhere on cgtalk, but I can't remember the url.

Anyway, that showed me it must be possible to tweak the brushes into aquarell-esque behaviour. I guess you would have to mind a certain way of doing strokes in addition to achieve a good effect.

Hi there,

here's the link to watercolor tutorial in ps7

http://forums.cgsociety.org/showthread.php?t=259965

In addition to a set of predefined brushes, the artist here makes use of sharpening and contrast filters (smart, isn't it?) to achieve the typical effects.

In fact, you can't achieve a proper watercolor look without special application-specific rendering support, be it automatic smudging of some sort or contrast/sharpness enhancement.

I wonder, master eyrich, are you considering adding watercolors for AW 1.0? I know this must be a lot of work... :?

It's on my todo list and it definitely comes before Artweaver 1.0 :)

After redesigning the GUI and improving speed and memory consumption, water colors are the next big step for Artweaver.

Hi hanzz,

glad you like it. I told you I did not actually want to do a caricature of you, but when it was done I looked at it and thought: "hello hanzz" - I am trying right now to get it done "on purpose", but I am just a beginner (studying the loomis material right now: big light bulbs are lit above my head... that stuff is great).

Anyway, when I tried to colorize my first attempt, artweaver crashed.
Boris: is that jitter-bug (funny, is that not a name of a dance?) to be expected with predefined dabs also? Because I use jitter and angular stepwise turning for the aquarells and I saw that dialogue again ("create dab?") before it crashed.

Sorry, hanzz, but with another few days of practice (loomis...) the result might look better anyway.

I will try and use some of those contrast/sharpen enhancements described in the above tutorial on the pic, too.

til soon :P

It seems to be the "well known" bug. But for safety, can you send me the brush xml file.

Here you go:

I saw that a previous captured dab for aquarells (which I don't use anymore) remained in the folder/dir. Just thought you would like to know.

It was the same bug. With the even released Artweaver 0.3.9.2 the bug is history :D

:D
cool...

you're productive, fast and responsive - actually I almost can't believe it's only you developing away at this faboulous software.

:shock:

Admit it - it's just a pseudonym and you are a pack of five or six hackers at play...lol


keep it coming and thx
