ShutterFest 2026 runs April 7–9 at the historic St. Louis Union Station Hotel — the annual gathering that has become the largest hands-on photography conference in the country. An optional SF+ day on April 10 extends the run for those who want deeper, smaller-group dives into advanced technique. The format is deliberately unstructured. Attendees build their own schedule from a mix of hands-on shooting classes, live demonstrations, platform lectures, vendor floor time, and open photo walks — all housed within Union Station, which the conference takes over entirely (save the aquarium).
