MatGlassGlassKit is not a store and not a marketplace. It is a set of focused digital tools for film photographers, large format shooters and darkroom workers — made to sit quietly beside the camera, the enlarger and the finished print.
The apps map to the way film work actually happens.

Read the light.

Learn moreArgentGlass Lab is an independent studio, quietly maintained for the long term. The name comes from photographie argentique — the French term for silver-based film photography. All six apps share one design language and one belief: leave the busywork to the tools, and keep the attention on the work.
Six ideas that shape every app in the collection.
Each app does a single thing well; together they make one complete, ordered workflow.
Digital tools in service of film — made to understand the craft, not replace it.
Like focusing on the ground glass: every reading, timing and setting aims to be reliable.
Quiet and restrained — the interface yields to the viewfinder and the darkroom.
Exposure, settings and process kept in full, so every frame can be revisited and repeated.
Built for people who practise the same craft — gathering and passing on what they learn.
All six apps are available now, built for iPhone and iPad.
