 "description": "The light meter and calibration are free, with no features removed. No ads.\n\nA film photography toolbox on your iPhone: light meter, viewfinder and exposure tools in one app.\nNever used a light meter? No problem. Measure, and the app says it in plain words: \"Keep the aperture at f/8 and set the shutter to 1/250.\"\n\nLIGHT METER (FREE)\n- Separate reflected and incident modes (a translucent film canister works as a diffuser)\n- EV, luminance (cd/m²) and illuminance (lux)\n- Solve for shutter, aperture, or the ISO you need\n- ISO 12–102400, f/0.7–f/512 (pinhole), 1/8000 s to 30 min. No artificial limits\n- Choose full, half or third-stop aperture scales so it never suggests an f-number your lens doesn't have\n- Readings are averaged over several frames so the numbers stay steady\n- Spot metering: tap the preview to meter just that point (Center returns to the whole frame)\n- Measure with the volume buttons, a self-timer, or the moment you release the Measure button (the volume buttons work with the phone flat against a wall)\n- Turn ISO with Camera Control on iPhone 16 and later\n- Long exposures include reciprocity-failure correction right in the answer\n- Hold a reading up to 50 times a day for free. The live numbers are always visible\n\nCALIBRATION (FREE)\nEnter the ISO, aperture and shutter from your own meter and tap Match This Reading. Reflected and incident are kept separately, and you can reset any time.\n\nVIEWFINDER (PRO)\n- Frame lines for 35mm, medium format, large format, Super 35 and more\n- Depth of field (near, far, hyperfocal) drawn inside the frame. It moves as you change the aperture\n- Add your own lenses and sensors (Sony FX6, Canon T5i and 7Artisans Spectrum included)\n\nSHOOTING LOG (PRO)\nPer roll: frame number, EV, ISO, aperture, shutter, lens, location, notes and a reference photo. Export to CSV.\n\nEXPOSURE TOOLS (DEPTH OF FIELD IS FREE)\nND filters, reciprocity, Zone System, and anamorphic desqueeze (load a photo, stretch it and save it).\n\nPRIVACY\nThe app never reads your clipboard. Logs, locations and reference photos are stored on your device and never sent to the developer (they are included in iCloud and computer backups, so they survive a phone upgrade). Everything works in Airplane Mode.\n\nPRICING AND AUTO-RENEWAL\nThe light meter and calibration stay free. Pro unlocks the viewfinder, the shooting log, the other exposure tools and adding your own gear.\n\n- Pro Monthly (3-day free trial)\n- Pro Yearly (3-day free trial)\n- Pro Lifetime: one payment, for all of today's paid features\n\nYour local price is shown before you buy. Monthly and Yearly include a 3-day free trial (once per person; not for Lifetime). Family Sharing is supported.\n\nPayment is charged to your Apple Account at confirmation of purchase. A subscription renews automatically unless auto-renewal is turned off at least 24 hours before the end of the current period, and the renewal is charged within 24 hours before the period ends. You can turn off auto-renewal or cancel at any time in Settings > your Apple Account > Subscriptions. If you move to a paid plan during a free trial, the remaining free period is forfeited. Restore Purchases is on the purchase screen and in the app's Settings.\n\nTerms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/\nPrivacy Policy: https://film-light-meter-mrk.web.app/privacy",
