FilmSlate Mobile vs Luma · Light Meter

FilmSlate ends the era of handwritten roll notes, lost negative sleeves, and "what camera did I shoot this on?" THE LOOP 1. Open the app. Type your roll's metadata — camera, film stock, ISO, lens, push/pull, project, notes. 2. Generate a digital slate — a photographable image with the metadata in editorial typography and a high-error-correction QR code at the bottom. 3. Photograph the slate on your film roll. 4. Shoot normally. 5. Get your roll back from the lab. Drag the folder of scans onto the FilmSlate Desktop app (free, at filmslateapp.com) and every image gets EXIF, IPTC, and XMP metadata embedded — Camera, Lens, Focal Length, ISO, Date, Location, Project, Keywords, Artist, Copyright. Lightroom (and Photos, and Capture One) instantly filter the entire roll. One photographed frame. A whole roll tagged. No accounts, no cloud, no monthly fee. WHAT YOU CAN STORE PER ROLL — Camera (Make + Model) — Lens (Make + Model + Focal Length) — Film Brand + Stock — curated catalog of 70+ stocks across 14 brands, plus custom — ISO, with push/pull stops — Project, Roll Name, Date, Location, Notes — Artist + Copyright — auto-stamped on every image in the roll Save reusable presets for cameras, lenses, and film stocks. The New Session form quick-fills from a single tap. SCAN EXISTING SLATES Already photographed a slate? Tap the Scan tab, point your camera at the QR, and it imports as a session on your phone. Useful for shared shoots, lab handoffs, or working across multiple devices. DESIGNED FOR FILM PHOTOGRAPHERS Built to feel like a darkroom apprentice — quiet, exact, and respectful of the craft of analog photography. DOES NOT REQUIRE — An account — A network connection (the QR is a self-contained payload — everything happens on your device) — Cloud storage of your photos (we don't see them) — A subscription LIGHTROOM-READY Every payload field maps to where Lightroom indexes it: Camera filter, Lens filter, Focal Length filter, ISO filter, Date filter, Location filter, Job ID, Keyword List, Creator, Copyright. Filter the whole roll by any combination, immediately, on import. THE COMPANION DESKTOP APP The metadata write-back happens on macOS. Free and simple — download it from filmslateapp.com. Drag-and-drop: drop a folder of scans, the app finds the slate frame, decodes the QR, and embeds metadata into every image in the folder. No subscription, no upload, no telemetry. FOR WORKING FILM PHOTOGRAPHERS If you shoot multiple cameras and film stocks, send to labs or scan at home, and live in Lightroom — this is the metadata bridge between analog and digital you've been keeping handwritten lists for.

A mechanical camera does not forgive an exposure mistake: on a roll of 36, you only see your misses at the lab. Luma answers the one question that matters as you raise the camera — which aperture, which shutter speed, for this scene and this film? No shot log, no frame counter, no hidden settings. One screen, three values. LIVE METERING Your iPhone's camera becomes the meter. Luma continuously reads the exposure the phone settles on and converts it into an ISO 100 normalised EV, smoothed for a stable reading. No photo is ever saved: the image is analysed, then forgotten. ONE RECOMMENDATION, NOT A LIST Luma shows a single aperture and shutter pair, chosen for handheld shooting: at least 1/125 s to stay clear of camera shake, then f/5.6 to f/8 where the lens is sharpest. When light runs short, it opens the aperture before slowing the shutter. THE DIAL Every equivalent aperture / shutter pair scrolls under your thumb with clicking haptic feedback, like the shutter dial on the body. Pick f/2.8 to lift a portrait off its background, f/16 for a landscape sharp front to back — the shutter speed follows. SPOT METERING Tap the viewfinder to place the metering circle on your subject: a backlit face, a shadow worth keeping. Tap the circle to return to average metering. IT REFUSES TO LIE When the scene falls outside the camera's range, Luma says so — too dark, too bright — and shows no values at all. A wrong recommendation would be worse than none. IT EXPLAINS Two lines under the values: what the shown aperture does to depth of field, what the shown shutter speed means for shake. Enough to learn, roll after roll. FILM STOCKS Portra 160/400/800, Ektar 100, Gold 200, UltraMax 400, HP5+ 400, Tri-X 400, Delta 100/400, Fomapan 100/400 — plus manual ISO entry for everything else, including pushed or pulled film. Your choice stays loaded for the whole roll. BUILT FOR A SPECIFIC CAMERA Luma is calibrated for a Nikon FM2 with a 28 mm f/2.8 lens: 1 s to 1/4000 s, f/2.8 to f/22. It serves any manual camera sharing that range just as well — simply transfer the values to the stops your gear actually has. Independent project, not affiliated with Nikon; trademarks are named only to describe compatibility. IT ASKS FOR NOTHING No account, no ads, no network access: Luma works fully offline and collects no data whatsoever. Free, no in-app purchases, open source. Please note: the app's interface is in French. Luma is an aid, not a guarantee — cross-check it against a reference meter on a few scenes before trusting it with a roll.
