So, after living on Boudewijn and Irina’s pantry for a week, we now have Soft Proofing working:
Tag: Krita
Didn’t get anywhere with my GSoC code today, so decided to start do some painting and doing the drawing challenge. Had some fun 🙂
Made the sketch in 8bit, and also did the flats in 8bit. Then went to 16bit int with linear space to do the mixing. Finally, overlaid the image with a slight pattern, set to overlay, and then converted to 8bit, to prevent banding artefacts. Ended up pretty well 🙂
So, while the 2016 Google Summer of Code hasn’t officially started yet, and Krita’s master is in feature freeze till the release at the end of the month, it’s a good moment to start preparing.
My area of specialisation within Krita is Colour Management, and my project is focusing on softproofing. This area is one that isn’t difficult in regards mastering intricate c++ methods, but rather an area that focuses on research. In other words, figuring out what is actually true.
It’s not quite certain why there is so much misinformation out there, a simple suggestion would be to say that perhaps a lot of colour management UI is just too byzantine to understand. But on the other hand, Western Society in general has had no single Colour Theory survive longer than a century until a new one showed up. So perhaps there’s just something about colour, and especially about how relative human vision is, that makes it difficult to capture in a single coherent theory, and most artists just develop a sense for color than a cohesive method.
My focus is on the softproofing, a sort of on-the-fly filter to emulate how an image will look when being printed(and more importantly, which details could get lost). I already researched this back in February, LCMS’s API will allow for it easily, and I now mostly need to sit down with Boudewijn to stare at Krita’s architecture to decide what is possible before deciding upon a UI and implementation.
However, in a discussion on IRC it was mentioned that it’d be nice if we could emulate not just cmyk profiles, but also things like colour blindess.
So, I did two important things recently.
First, I posted my 101 sketches I made with Krita since I started working on it. I made a google+ album out of it, because I didn’t think this server could hanle 101 sketches easily. (Update: google+ died, so now they’re here.)
Secondly, I formally open sourced my little SVG comic reader with GPL 3.0 (which I think is sensible for a web-application.) You can find it on github here: https://github.com/therahedwig/SVG-comic-reader
I actually made it 2.5 years ago, but I never formally open sourced it, more forgot about it, actually. When at the Krita sprint, Boudewijn remarked he really disliked the way how webcomics present themselves, I remembered it again and show it to him and Timothée Giet. Timothée, as a comics creator was interested in using it, and I finally took the step to open source it.
It has quite a few features, so check out the readme at github.
First test with two point perspective 
second test 
Test of drawing several characters of mine, was looking in particular for 
finally trying out all sorts of perspectives 
Having fun with the mirror tool 
Having fun with a cloud brush 
More clouds 
Space clouds 
Failed kiki 
Test image for the newly coded concentric assistant 
Mermaid idea 
Another fish eye test 
This one was shaded by painting normals and then shading with the phongbumpmap filter. 
More fun with fisheye 
attempt at bg for animation, never got nywhere. 
I think this one’s a test of color theory, using add and divide to get brighter colors rather than just mixing. 
Trying to figure out a fire fairy character 
Sketches of people lying down 
Wanted to try one of those weapon sketches, didn’t wor out. 
Typical sci-fi tube thing 
Further development of the fire fairy character 
Playing with the greater mode. 
Attempt at making a city scape, got too tired before it got out of the ugly phase. 
Muscle sketches, don’t draw men enough. 
Lightning test 
Wide gamut image that I used to test softproofing. 
Feet sketches. 
Handsketches 
So, after the Tangent Normal Brush was merged, Krita didn’t have any new releases because it was decided to do some major bugfixing. Which in turn means I haven’t had any bugreports yet.
That meant that for the rest of my GSoC, I instead worked on a secondary project: An improved GUI/Widget for picking profiles in Krita, which I merged today.

Some faces in Krita
Did some face-studies for character designs in Krita past week as a way to relax. I can´t stop detailing the woman, so I am posting now to stop myself.
So, as the saying goes finishing something up to 90% takes as much time as the last 10%.
Anyway, important things first:

Failed Timelapse
I had intended to record a timelapse of her, but only saw after finishing it that I didn’t press ‘record’… Took about 1 hour and 20 minutes on this.
So, a while back I added new assistants to Krita.
The demonstration for how to use them is here:

And here’s some images I did with them:

| Iván Yossi | Great work! i’ve tested them and they work great. 😀 |
So, in the past few weeks, I spent some time hacking a new feature into Krita that I had wanted for a long time, and this monday I actually commited it. So, I figured it be best to make a little post about the new functionality.
