Having some fun

I didn’t find time to draw just for fun during the last couple of months. I worked on so many commissional and non-commissional projects that I started to miss drawing silly things. After my graduation I found some free time and an unused sketchbook in my atelier…. nothing could hold me back anymore :).

Drawing random things isn’t just fun but also helps to generate ideas for future projects. Also it helps to find new styles and trying out different techniques. I posted the complete sketchbook below. I hope you like it.2014-02-19-Skizzenbuch-Spass-am-Zeichnen-00 2014-02-19-Skizzenbuch-Spass-am-Zeichnen-01 2014-02-19-Skizzenbuch-Spass-am-Zeichnen-02 2014-02-19-Skizzenbuch-Spass-am-Zeichnen-03 2014-02-19-Skizzenbuch-Spass-am-Zeichnen-04 2014-02-19-Skizzenbuch-Spass-am-Zeichnen-05 2014-02-19-Skizzenbuch-Spass-am-Zeichnen-06 2014-02-19-Skizzenbuch-Spass-am-Zeichnen-07 2014-02-19-Skizzenbuch-Spass-am-Zeichnen-08 2014-02-19-Skizzenbuch-Spass-am-Zeichnen-09 2014-02-19-Skizzenbuch-Spass-am-Zeichnen-10 2014-02-19-Skizzenbuch-Spass-am-Zeichnen-11 2014-02-19-Skizzenbuch-Spass-am-Zeichnen-12 2014-02-19-Skizzenbuch-Spass-am-Zeichnen-13 2014-02-19-Skizzenbuch-Spass-am-Zeichnen-14 2014-02-19-Skizzenbuch-Spass-am-Zeichnen-15 2014-02-19-Skizzenbuch-Spass-am-Zeichnen-16


Concert poster: Ben Schadow

The Take Berlin concert was absolutely great. I loved this band and hope that I can work for them in the future ;). Anyway, the show is already past and there is another event coming up soon: Ben Schadow and his support “Die Knopiloten” are going to play at the Treibhaus Luzern. The text and the outlines were drawn with ink and the whole coloring was made with photoshop (it took me ages to finish this piece).


Master of Arts in Design: A project about violence

Hey there!

The main reason, why I didn’t post so often were my master studies. Two weeks ago, I’ve graduated and hope, that I can share my knowledge about illustration and art more often from now on. I am quite happy about the fact, that I finished my master project about violence just in time. The result of my project came out pretty well, even though I am not satisfied with every aspect. I am happy that a lot of people liked my work and had the possibility to write a little article for the NZZ Campus (only German, sorry). Click on the image below, to see the original article and some more pictures.

Concert Poster: Valdimar & Kapnorth

Hey there!

I have had a quite stressful time recently but finally I’ve just finished my master course. Beside this I had to do some commissions and one of them was the poster artwork for the Valdimar concert. Actually I had not much time and energy for doing other things beside my studies. Therefore I was surprised by myself how good the outcome was.

Once again I decided to paint it with ink and to add colour digitally. A part of the workflow and some details can be seen below. Hope you like it.

Concert poster: Nadine Carina

Hey there!

Once again I had the opportunity to make a concert poster for the venue Treibhaus Luzern. Even though I am quite stressed with finishing my master studies I’ve found some time to do the artwork for Nadine Carina’s concert. The last two posters for the Treibhaus were made 100 % digital. This time I wanted to do it mostly analogue. And this is the outcome:

And additionally two image details:

The image details show a big advantage of an analogue image. The original painting’s size (just the girl) is about 12cm x 22cm. This size allows to work efficiently and it doesn’t take so much time to finish it. Now the big advantage of such kind of panting is, that you can blow it up and it will still look good. Mostly I am completely overwhelmed by the richness of details you’ll find in the blowup. A digital image mostly doesn’t come with this feature and that’s why I try to work as much as possible analogue.

Well, let’s say something about the workflow. Of course you’ll need the idea firstly. I had a quite clear vision from the beginning and that made it quite easy. Firstly I needed a reference photo of Nadine’s Face. Therefore I watched several of her videos on youtube until I found the one i was looking for. I prefer to use video stills as reference material because of copyright problem. Additionally it is also boring to use a picture that was used for another purpose in advance. With the help of the photo I was able to make a quite rough digital sketch. This was the source for the first pencil drawing (image below). After I used a hard pencil to trace it onto an aquarelle paper. I prefer to have an accurate line drawing because it makes the colouring process much easier and faster. But still, it took me about 8h to finish the colouring part. After I had to write the infos. I was already a bit tired and that’s why I had to write the infos over and over again. But it looks quite interesting in a way (last image). After I just had to scan all parts and bring them together in Photoshop. The watercolour always looses a bit it’s brightness when being scanned. Because of that it was necessary to make some colour adjustments. Well, that’s it!
Hope you liked it and got inspired of it. If you have any questions just ask! rafael-koller-luzern-zuerich-schweiz-illustration-fiction-portfolio-nadine-carina-music-treibhaus-concert-poster-artwork-h550-036-Skizze2

Current Work

Hey guys!

Today I want to show you a detail image of a project study. (I hope that I can show you the finished work soon. )

I found out that it makes lot of fun to paint on dark carton panels. It’s an easy and fast way to make good looking sketches. Only a few brush strokes can give you an idea how the final work could look like. But it makes only sense when there are a lot of darker tones in the painting. Otherwise I prefer skin tone groundings.

The image below shows just a bit of the of the unfinished sketch. (The size of the image detail is about 6x9cm.) If you have any question, please feel free to ask!
