HDR Support in Krita


Boudewijn Rempt

In 2018, 2019, we have added support for working directly in HDR to Krita. It’s Windows-only for now, until other platforms start supporting HDR at a system level. HDR makes a great difference: more contrast, wider color gamut make for far more expressive images. Since HDR for DCC applications is very, very new, this presentation will give a short introduction into what HDR actually is, what the complications are and what we needed to do to implement HDR in Krita. If I can get someone with a car to help me out, there will also be actual hardware to play with during LGM.

Boudewijn Rempt has been the Krita maintainer since 2004. Krita is the powerful free and open source full-featured digital painting application for illustrators, animators, comic book artists and texture and matte painters.


Turning the Community into a Business


Tatica Leandro

A career is not always built in your university halls, sometimes it is built online. During my presentation I would like to show you how I turned 10 years of community experience into a business without loosing the focus. Working exclusively with FLOSS tools in a design environment, and with clients from all around the world, puts your ability and experience to a real test, always working towards providing clients with a quality result.

It’s possible to make a living from FLOSS design tools, take it from someone who handles photography for supermarket chains, restaurants, fitness, modeling, weddings, family and newborn, events using exclusively darktable and GIMP, and from someone who builds marketing campaigns for Ford dealerships, beer brands, fashion designers and more, using exclusively Inkscape.

Tatica Leandro – I’m a full-time designer, photographer and community people. I love to analyze how this interactive world works. I’m not a programmer, however that’s how I started. I have been in the field since 2005 and have been loving every minute of it.

I love to learn and teach what I know about FLOSS and I enjoy meeting new friends from all around the world.


Generating video in realtime with recurrent neural networks


Douglas Bagnall

I will talk about artworks based on Gstreamer plugins that learn patterns of movement from video they watch, whilst simultaneously generating new video based on those patterns. In one example, each pixel decides how to change based on its history and neighbours, while in another the video is generated using a recursive top-down approach. This works in realtime on not very flash CPUs.

Douglas Bagnall has been an artist and programmer for ages. He lives in Wellington, New Zealand and works as a Samba developer.






(Sensual) Portrait photography and post production


Stefan Schmitz

Workshop (4-6 participants per session). The participants will work with a model, make use of the available light and process the shots in darktable and Gimp. Every participant shall bring his own camera with a fast standard lens; ideally a prime lens, opening at 2.8 or better.

Stefan Schmitz – husband, father, engineer and photographer, the latter for 40 years. Specialized in sensual and nude portraits. Linux enthusiast since 2002, avid user of FOSS. Born in Germany, left for the US of A in 90, back to Germany in 94, living in France since 95.


Creative coding with Shoebot


Ricardo Lafuente & Stuart Axon

Shoebot is a Python tool for creative coding. It rides the same wave as projects like Processing, DrawBot, Paper.js and others in that it provides an easy entry to programming for newbies by providing immediate graphic feedback, but it’s also a powerful tool for seasoned hackers to create useful outputs through inventive scripting. Shoebot specialises in vector graphics, and shines as a hacker-friendly tool for generating images with Python.

This workshop is meant to introduce Shoebot both to coding novices and experienced developers. We’ll showcase the latest developments in the tool (Jupyter notebooks, editor plug-ins, and other cool features), and take the time to hack together new examples and experiments to showcase what Shoebot is capable of. Whether you have coding chops or not, if you feel like contributing to a small but useful libre graphics project, drop by and let’s generate awesome pictures and animations together.

Stuart Axon and Ricardo Lafuente are the main developers of Shoebot, a Python vector graphics library initiated in 2007 and first showcased at LGM 2010.


Comic Book Workflows


Tom Lechner

Practice and discuss various open source workflows for comic book creation, from start to finish. Come and explore how to use a combination of open source illustration, layout software, and even 3D modelers for all stages of production, from mockups to finished book or even online animated webcomic, perhaps with the Godot game engine.

Tom created Laidout to lay out his cartoon books and experiment with interface design. He is an artist living in Portland, Oregon, USA.


Transient Mainstream for Pi’s


Peggy Sylopp

Pure Data is made for music creation, but can be used also for interactive grahics. PD provides some simple motion detection objects, which I used for my video installation „Transient Mainstream“ in 2005, connected with the graphics of vvvv. The challenge now is to let the same project run completely with pd on a Raspberry Pi, which worked fine 2016 in Porto Allegre, Brasil. During this workshop I’d like to show you how I made it!

Peggy Sylopp – Artist and computer scientist, work nowadays with interactive haptic analog sculptures made of ice, sound and lights
2009 Sound-video installation „SPECTRUM“ added into Skulpturenmuseum Marl
2008 Nomination German Soundart-Price






Lightning Talks





Quentin Juhel

Since few years, there is a community growing of graphic designer, researcher and students, which are using or building free software for their publishing workflow. The group « PrePostPrint » results of the desire to gather friends and identified graphic designers who share the desire to re-think the chain of publishing. We want to forego the classical DTP programs. Coding becomes a design tool that permits to reinvent the editorial process, and allows to continuously question and re-invent publishing forms and formats.

PrePostPrint is an informal research group for alternative free publishing workflows. We are specifically interested in the creation of hybrid and printed publications with web technologies. It’s taking shape throught a wiki page and a mailing list and events n Paris and Bruxelles for now (synposiums, workshops, meeting or fair, at La Gaité Lyrique, EnsAD, Parsons School…).

Through this organisation our purpose is to regroup actor and ressources to share our research, projects and tools. It is important for us to communicate to a novice public (student, teacher, graphic designer, publisher…) these alternative editiorial process. As a srike power, PrePostPrint wish to interfere in design education places and provoke a craze for this practice.

Quentin Juhel is a graphic designer who is interested in digital tools and their alienating power over his user and practice, whether he is a designer or a fan of modern technology. Since 2017, is a researcher at EnsadLab – Paris, École Nationale Supérieure des Arts Décoratifs, and a member of PrePostPrint. In the research programme, Hybrid Publicisation – Reflective Interaction (EnsadLab), he develop a problematic about the influence of free software, or at least the free culture, on the shapes of graphic design.


freieFarbe presents an Open Standard for Professional Colour Communication


Jan-Peter Homann & Holger Everding

Libre Graphics programmes enable the creation of colours just as much as commercial software. However, very few can handle colour libraries other than in basic RGB. Even worse, when it comes to define highly accurate colours, users traditionally rely on spot colours from commercial colour libraries (such as Pantone, RAL or HKS) which cannot be distributed with Libre Graphics products due to commercial licensing models.
freieFarbe e.V., a non-profit association from Germany and Switzerland, has begun to change the game. We promote to use mathematical colour systems that are available in every computer, free of licensing, and easy conversion for every type of output.
Supported by the German Institute for Standardisation (DIN), several companies involved in graphics and printing, as well as the Scribus Team, we devised the DIN SPEC 16699 Open Colour Communication. It describes a natively digital approach to colour communication using the CIELAB HLC colour model, from the first step of design until the last step of colour formulation. Within the project, we created a Colour Atlas as reference for the HLC model. It is available in both digital and in physical form. Our printed HLC Colour Atlases are produced in a precision rarely matched by commercial vendors. Digital colour libraries including Spectral data enabling data exchange with producers of ink etc. are available under the zlib licence. . are also freely available.

With our presentation we hope to start a dialogue with the Libre Graphics Community about our approach to liberate colour.

Jan-Peter Homann -Self employed colormanagement specialist Berlin/Germany since 1991. Author of the book „Digital Colormanagement“ working closely with standardization bodies like ICC, ISO and DIN. Active member of freieFarbe e.V.

Holger Everding – Software developer from Oldenburg/Germany
Since 1995 mainly active in the field of colour related software products (Digital Colour Atlas and for RAL, NCS, Brillux, HKS and others)

Flowers and samples — an audio reactive self exploration.


René Dudfield & Macarena Pivaral

Using the FLOSS multi media toolkit pygame, we have been working on an audio reactive visualizer and audio sampling project. In order to explore aspects of music, cross cultural communication, education of graphics programming, musical education, and further our artistic practices. This video synth is made using an accessible programming language (python), and is made to run on cheap portable computer hardware ($20-$40 computers). The specific idea of working with flowers is inspired by the relevance of flowers in Quechua names, also Spanish names and sayings. Working with this program with any kind of other image opens the possibility of reframing signs in a new representative system creating meaning /significance and exploring the dialectic of action and reaction inner process and outside (is there an outside?) supported also by the music medium. Visuals are here not in a static position since they react to music, changing from moment to moment. As a pedagogical tool, we are exploring ways of inspiring people interested in visuals, and music making who might not otherwise be inspired to create graphics. The audio looper component, and the visual reaction component makes generating graphics immediately accessible to anyone who can make a noise or move.

Macarena Pivaral was born in Argentina where she studied music. Now based in Berlin for 9 years, where she continued studying and working in photography and music production increasing her interest in electronic audiovisual projects. She is active in the field of intercultural training and music therapy with a focus on clinical work and migration.

René Dudfield is an author of pygame, the most popular game and graphics library for the python programming language. He works as a freelancer mostly focused on interactive media, apps, and visualisations. He has been based in Berlin for the last 8 years after living in 10 other cities including Melbourne and London.






NO DOTTED LINE: Making a remixable sex ed book


Nor Greenhalgh

NO DOTTED LINE is a remixable sex ed book about healthy consent. It’s made of lavish illustrations, created with libre graphics software, and every visual element is available for remixing and re-use. In good consent there is no „dotted line“, no final deal – all is provisional; iterations are welcome as desires shift. This illustrated book likewise has no final version, and evolves with the instincts of its reader-writers. In this workshop I will introduce the first versions and we will play with the images, re-mixing them using free software (Inkscape + GIMP) and analogue collage. The project demonstrates a libre workflow in all senses of the word – promiscuous, consensual design created with free software and released for re-use.

I am an artist & mental health worker, with an interest in the philosophy and application of open source/collaborative working practices. My background is in both participatory visual arts and feminist activism: I facilitate projects which invite contributions from others, using open source tools and methods. Alongside practising as an artist I have worked as a consent educator in schools and as a mental health worker with survivors of sexual violence. Since completing a Masters in networked media I have facilitated workshops exploring copyright licenses, voting systems and consensual drawing machines. I recently developed an open source community archive documenting the history of every address on my street, I live in Oxford, UK.


3D photography


Tobias Ellinghaus & Henrik Elburn

This is a hands on follow up of the „Photography of the future“ BoF from last year. We will provide both a camera array and a prototype of a new lens that enable the user to take images with depth information. People will be able to play around with those and learn about the techniques used.

Tobias Ellinghaus is a contributor to darktable and a few other open source graphics tools. He also dabbles in photography with varying success.

Henrik Elburn is a professional photographer.

Both work in a project that develops the K-Lens which will be presented in the workshop.


Paged.js: use CSS to design books


Julie Blanc

Paged Media is a community with the goal of advocating for the use of CSS Paged Media. We are creating open source tools to support using print CSS with current browsers. In recent months we have been working on developing Paged.js, an open source JavaScript library that paginates content in browsers.

The tool is based on the CSS standards written by the World Wide Web Consortium (W3C). W3C publishes documents that define Web technologies (including CSS) which are considered Web Standards. W3C modules are published publicly throughout the process of their development until they are finally released as a W3C Recommandation. The print modules are at various stages of the process, but most are still in the Working Draft stage. So, not implemented in browsers.

Paged.js act like a sort of polyfill for these modules: it can parse CSS stylesheets, polyfill the print declarations (by updating them with supported styles or replacing them with JavaScript implementations) and present a paginated rendering of the HTML document using the fragmentation provided by CSS columns. It’s also easy to add other scripts to increase the possibilities of layout and style.

We have been developing this library for one year and we are also working on a tool to generate PDFs using a headless version of Chrome. The code is open-source with a MIT license and the development is community-driven. We have several tools to help designers and discuss the addition of new features. There are already projects using this library (PageDown, Ovide…) and designers use it in their publishing projects.

We propose to present paged.js during a workshop in several parts:
— A designer look at how paged.js handles pagination and what designers can do with the tool with the description of the CSS specifications used in paged.js and a book typesetting demonstration.
— A look at the state of paged.js today, what it can do, what’s missing, and what initial projects are being built on top of it.
— And finally, how paged.js works under the hood and how to override styles, and how to add other JavaScript libraries to tweak the output (this part was addressed to those who were most technically comfortable, maybe we won’t have time to do it).

Julie Blanc – I’m a French graphic designer and researcher. I works on the pagedMedia initiative and I am part of the development team of paged.js, expert in CSS. I have already conducted several workshops with paged.js (in English and in French). I’m also an active participant in PrePostPrint, an informal group of people (mostly in France and Belgium) that is interested in alternative free publishing workflows, particularly in the creation of hybrid and printed publications with web technologies. I also preparing a phd in ergonomics and design at the University of Paris 8 and at EnsadLab-Paris. I’m particularly interested in the recent shift from desktop publishing to web technologies and methodologies (HTML5, CSS3, javascript, epub) in editorial workflows and design practices.
