## The Portrait League – Paid Studio Sessions for Serious Hobby Photographers This is a structured portrait community — not a casual meetup. The Portrait League is a recurring studio (location) gathering for photographers who want to improve their portrait and headshot work in a focused, constructive environment. Each session will focus on a specific studio concept: – Classic 1-light headshots – Dramatic low-key portraits – High-key commercial looks – Editorial portrait setups – Creative color lighting Model included. We don’t rush for quantity. We work for quality. The goal is simple: Refine technique. Improve consistency. Develop a recognizable portrait style. This is for photographers who: • Want structured growth • Value critique over ego • Take their craft seriously • Prefer collaboration over chaos Spots are limited to maintain quality and productive energy. Investment Today: €15 Duration: approx. 2–3 hours If you want random shooting, this isn’t it. If you want to level up your portrait game, join the league. ***

## Editorial Boudoir Lighting Session **Limited to 3 Photographers** An intimate, structured boudoir session focused on controlled lighting, refined posing, and intentional composition. This is not an open group shoot. The atmosphere will be calm, directed, and professional. We will work with: • 1 professional model • 2 curated lighting setups • Guided posing and direction • Structured shooting rotations • Time for questions and breakdowns The focus is on building strong portfolio material while understanding how to shape light and mood in an editorial boudoir environment. Spots are strictly limited to three participants to ensure quality, space, and creative control.

**What is Innate Dance?** Innate Dance is a joyful approach to movement, which invites deeper embodiment and self-connection through butoh inspired movement, Noguchi Taiso exercises, the Seki Method, somatic attention and imagination. We shake it out, breaking up stuck energy held in the body, and explore new movement possibilities from a place of alignment and sensitivity. Thanks to our open awareness we can be surprised by lesser-known parts of ourselves and come to appreciate our innate wisdom in movement. Through exercises, explorations and improvisations we build trust in the body that knows how it would like to move and express itself, and when we follow our innate dance, it just feels good! There is also time and space to dance freely, to enjoy the music in your body and to let go! Ultimately, it's about feeling more 'in' our body and grounding joy. **When? Where? How much?** **Mondays 19:30-21:00** in Studio 2, Tanz\*Hotel, Zirkusgasse 35, 1020 Wien Try out € 16\,\- \| One class drop\-in € 21\,\- \| Student € 10\,\- \| 5 x class pass €95\,\- \| 1 x class pass for rest of semester € 224\,\- \(or €16/class\) **Who teaches the course?** Jess is a dancer and psychotherapist (humanistic and integrative), who loves shaping classes that offer the space to explore the many facets of being human. Sometimes this learning involves physically embodying non-humans like trees, fish and wind, so we can get out of our limited-human-thinking-mind and into the bigger wisdom available through imagination and our body. At other times it's about dancing textures, sensations or taking on the energy of parts of ourselves so we can know them better. Jess has danced all her life and has been exploring butoh dance for the past eleven years alongside her psychotherapeutic practice. She is co-author of *The Seki Method - Basics* (now available to buy online via website), is a Seki Method Facilitator, and was a 2024 student at the Im_Flieger Schule researching dance and healing.

When judging morality, should we prioritize **intentions/duty** or **outcomes/results**? It introduces two influential philosophers as representatives of these approaches. * **Immanuel Kant (deontology):** An action is moral when it is done from **duty** and follows rational, universal principles (the **categorical imperative**). Certain acts—like lying—are wrong regardless of the consequences; you can’t do a wrong thing for a right reason. * **John Stuart Mill (utilitarian consequentialism):** The morality of an action is determined by its **effects**, specifically how much **happiness/well-being** it produces. Mill argues that some pleasures are “higher” than others, and that good intentions don’t redeem harmful outcomes. ## Discussion Questions 1. **The lying dilemma:** A murderer comes to your door and asks if your friend is hiding inside. Kant would say you must not lie. 2. **Can good intentions rescue a bad outcome?** 3. **The organ harvest problem:** A surgeon has five patients dying of organ failure and one healthy patient in for a checkup. Killing the one to harvest organs would save five lives, and the math works out for the utilitarian. Why does this feel so deeply wrong? Is that feeling a point in Kant's favor, or just a bias we should overcome? 4. **Do rules need exceptions?** Kant insists moral rules must be universal, with no exceptions. But most of us can imagine extreme scenarios where any rule seems like it should bend. Does the need for exceptions fatally undermine deontology, or is the strength of the system precisely that it refuses to bend? 5. **Who gets to calculate the consequences?** Utilitarianism asks us to maximize good outcomes, but we're notoriously bad at predicting consequences. If we can't reliably know the results of our actions, is it practical to base our entire moral system on outcomes? Does this uncertainty push us back toward rules and principles? 6. **Everyday morality:** Think about a real moral decision you've made recently, even a small one. Did you reason more like a Kantian (what's the right thing to do in principle?) or more like a utilitarian (what will produce the best result?)? Do most people naturally lean one way? 7. **Justice vs. the greater good:** A town can prevent a deadly plague by sacrificing one innocent person. The greater good is clearly served. But is it just? Can an action be morally right and deeply unjust at the same time? 8. **The big synthesis question:** Are these two systems actually opposed, or do they often arrive at the same answers by different paths? Is it possible that we need both: rules to guide us in the moment and consequences to evaluate systems and policies over time?

**Talk Description** For most of Python's history, the predominant option for documentation has been Sphinx and reStructuredText. However, a majority of other ecosystems have adopted Markdown. There are historical reasons for reStructuredText being a better choice, however, Markdown is now up to the task. In this talk, you'll learn why Markdown is a better option for your project's documentation. You'll be introduced to MkDocs, a static site generator built around Markdown content, and a series of associated plugins and extensions that you need to bring Sphinx-like capabilities to Markdown documentation. You'll hear a case study of migrating multiple large, existing Sphinx-based documentation bases to Markdown, including the tools used for automating the process. You'll learn how you can engage the community to assist with the effort. Finally, you'll learn why it's worth the effort to make a change of this magnitude. **Agenda:** 7:00pm - Opening announcements 7:10pm - Switching from Sphinx to Markdown 7:50pm - Q&A
