The light meter
you already own.
Stop paying $299 for a handheld you use twice a month. Pellica's meter is free, calibrated against a Sekonic L-858, and logs straight to the frame you're about to shoot.
Incident. Reflected. Spot.
Pick the right one for the shot.
Incident metering
Point your phone at the light source — or better, stand where your subject is standing and aim the camera back at you. Pellica uses the front camera + a digital diffuse-dome model calibrated against a Sekonic L-858.
Reflected metering
Point the rear camera at what you want to meter. Pellica averages the scene using a center-weighted pattern that matches the metering curve of a classic Pentax Spotmatic.
Spot metering (5°)
Tap anywhere on the live preview to meter that exact zone. 5° cone, matches most hand-held spot meters. Includes a Zone System overlay (0–X) for Ansel-style previsualization.
Filter factors, handled.
Stack a yellow #8, an orange #21, and an ND 0.9. Pellica does the math — 5⅓ stops — and gives you the corrected shutter instantly. 40+ filters in the library, or enter a custom factor.
Calibrated. Tested. Trusted.
We tested Pellica against a Sekonic L-858 Speedmaster and a Gossen Digisix 2 across 1,200 readings in daylight, tungsten, mixed, and fluorescent light.
Meter, then log it — without switching screens.

"Log to frame N"
One more tap. The reading, your adjustments, and the scene all become frame N of your roll.
Straight answers.
Accurate enough for film?
For 99% of shooting, yes — especially with negative film, which has 12+ stops of latitude. Within a third of a stop is more than enough for Portra or HP5. For critical slide work where a third stop matters, we recommend a handheld. Pellica’s spot mode is good enough for most Zone System work.
Does it use the flash / LED?
No. Pellica reads ambient light only. Flash metering is planned for a future update — we will ship it to both stores the day it is ready.
Does it work in low light?
Down to about EV 2 reliably (a dim room). Below that, the iPhone’s sensor noise starts to dominate and the reading gets noisy. For concerts and night photography, bracket anyway.
Can I calibrate it against my handheld?
Yes. Settings → Meter → Calibration offset. Set a permanent plus/minus third or half stop bias if your Sekonic reads differently in your studio.
Does the meter drain battery?
Barely. Readings use the back camera sensor briefly — about two seconds per reading. A full shoot day drains under 3% battery on a recent iPhone or Pixel.
Where can I get the meter?
Included free in Pellica on App Store and Google Play. No separate app, no in-app purchase — the meter is part of the core tracker.
