ARTLab: Darkroom Workshop – Sunlight Prints

Have you ever developed images in a darkroom? Are you curious about how sunlight is used to create images? Have you ever used a darkroom that is part of an art installation? Whether you are a beginner or an experienced photographer, this workshop is designed to inspire creativity and foster a deeper understanding of the art and science behind photograms – a technique sometimes called cameraless photography.

Engage in the magical process of using the power of sunlight to create one-of-a-kind prints at Mattress Factory’s ARTLab: Darkroom Workshop. Experiment like an artist and learn about the darkroom process hands-on with an art educator in a small group. 

During the workshop, you will learn how to manipulate light and shadow to capture fascinating images. The darkroom is a feature of Luke Stettner’s exhibition, “State of the Sky”, which uniquely uses sunlight through a roof opening – instead of artificial light – to develop images. 



Each $40 ticket includes admission to all Mattress Factory galleries. Your selected time slot is the time you must check in at 516 Sampsonia for your darkroom session. You are free to explore the rest of the museum anytime before or after!

All materials will be provided to experiment in the darkroom and produce your own prints that can be taken home after the workshop.



The workshop is a 45-minute session.
