Photo Class: Photographic Composition – Essential Techniques
Photo Class: Photographic Composition – Essential Techniques
THIS CLASS IS OFFERED THROUGH CAPITAL PHOTOGRAPHY CENTER **PLEASE REGISTER WITH CAPITAL PHOTOGRAPHY CENTER, NOT MEETUP!** https://capitalphotographycenter.com/classes/class/2026-02-01-photographic-composition-essential-techniques The composition of a photograph is the single most important element a photographer uses to convey an artistic statement. What’s included, excluded and the arrangement of elements within the frame is all part of composition. This class will teach you techniques to improve the composition of your photos with hands-on shooting experience coupled with feedback. Join instructor Michael Koren as you learn about composition in the Postal Museum and Union Station. The class begins with a lesson and viewing examples of compositional techniques from master photographers to help you when composing your own photographs. We'll then go to specific locations to practice those composition techniques. Afterwards, participants will have free time to photograph all the museum has to offer. We’ll follow up with a gentle critique and feedback of your best work of the day. This class is about "seeing" stronger images. Any camera will do from DSLRs to mobile phones. If you *are*bringing a DSLR or mirrorless camera, lenses in the range of 18-135 would work well. No tripods allowed for this class. Questions can be directed to Marie Joabar at info@capitalphotographycenter.com. Class limit: 8-10 *** **THIS CLASS IS OFFERED THROUGH CAPITAL PHOTOGRAPHY CENTER** https://capitalphotographycenter.com/classes/class/2026-02-01-photographic-composition-essential-techniques

The 5Rhythms® of Flowing, Staccato, Chaos, Lyrical, and Stillness form ‘The Wave’, a simple movement meditation practice that encourages us to find our own movement into presence and embodiment, discovering ourselves at our most fluid and creative level. The Rhythms are different ways of moving that are related to different ways of being in the world. As we practice them, we bring more of ourselves –body, heart, mind & soul- into movement, on the dance floor & out in the world. There are no steps to learn and it can be enjoyed by anyone, regardless of age, fitness, ability, or experience. Our dance is an individual and collective experience. How much you choose to interact with other dancers is up to you. We ask only that you come with a heartful respect for yourself and every other person on the floor. The 5Rhythms teacher is here to help take you deeper into the experience, when you’re ready. There are no steps to learn. 5Rhythms can be practiced by anyone regardless of age, fitness, ability, or experience.

AI Development Risk Case Studies and how Agentic AI is the future of Appsec
AI Development Risk Case Studies and how Agentic AI is the future of Appsec
OWASP is ending use of Meetup, so I built an eventbrite for the event. https://www.eventbrite.com/e/ai-development-risk-case-studies-and-how-agentic-ai-is-the-future-of-appsec-tickets-1981450622150?aff=oddtdtcreator AI is transforming how software is designed, developed, and deployed, dramatically accelerating velocity while introducing new categories of risk. As organizations adopt AI-assisted coding, autonomous agents, and increasingly complex model interactions, traditional application security approaches struggle to keep pace. This talk examines emerging AI-driven risks through real case studies from the field, highlighting issues such as insecure code generation, data-leakage pathways, model manipulation, and evolving supply-chain threats. We will explore how engineering teams must adapt their people, processes, and governance models to secure AI-augmented development workflows effectively. The session will then introduce agentic AI as the next evolution in application security—autonomous systems capable of continuous analysis, multi-step reasoning, and real-time remediation. Attendees will learn how combining agentic AI with modern practices can reduce developer friction, improve coverage, and create a future-ready application security strategy designed for the demands of AI-native software development
