Grainium

Grainium is the analog ecosystem — six precision tools, a community of working film photographers, an AI built for film, and a worldwide directory of labs and camera shops, all in one app.

CAPTURE & MEASURE

• Light Meter — incident and reflective metering with film-specific reciprocity correction
• Colour Temp — Kelvin readings calibrated for daylight and tungsten stocks
• Zone Reference — Train your eye to estimate subject distance for sharper zone focusing

DEVELOP & PROCESS

• Dev Timer — push/pull-aware multi-bath timers with haptic step alerts
• Safe Light — true-red darkroom mode, coin-test calibrated
• Negative View — instant in-camera positive preview for inversion

DISCOVER & SHARE

• A worldwide directory of film labs, repair shops, and analogue camera stores — find what's near you, find what's worth a flight
• A community gallery to publish your work, follow photographers who inspire you, and find your next favourite film
• Photo walks, meet-ups, gallery openings, expos — find local events or host your own
• A blog of field notes, gear reviews, and darkroom guides from the community

GRAINIUM ASSIST — AI BUILT FOR FILM Ask anything: identify a roll from a half-remembered design, plan an exposure for an unfamiliar stock, get a starting recipe for a push to 3200. Grainium Assist is trained on the language of film photographers, not generic photo metadata.

WHY FILM PHOTOGRAPHERS LOVE GRAINIUM Six precision tools that fit in your pocket. A community that actually shoots film. AI that knows film and development. And a directory of every lab worth knowing.
