Mask Compositing

Compositing is the process of combining visual elements from different sources into a single cohesive image or scene, often creating the illusion that they belong together. Mask compositing is a specific technique within compositing that uses masks to selectively reveal, hide, or blend parts of these elements, allowing for precise control over how they interact within the composition. While this is typically done easily with digital software, this workshop offers an alternative for those who prefer to avoid digital tools. Instead, we will explore a hands-on, analog approach that embraces imperfections and a slower, more tactile process.

In this expanded cinema workshop, participants will learn how to create composite images using analog methods and multiple projections. At the heart of our exploration will be 35mm glass slides. Participants will mask, cut and collage found 35mm slides to project "impossible" images. By combining multiple projections, they’ll apply the principles of masking and compositing in a physical, tangible way.

To introduce a dynamic element, participants will also create movement effects using mechanical shutters. As part of the workshop, participants will construct motorized external shutters. They will design, craft, solder, and assemble shutter components.
