Long Exposure Timer vs PocketMeter Pro

If you shoot long exposures, you've been there. You are wading in a stream (or the snow, dark, or any of other adverse conditions we routinely face). Trying to do the mental math to add ten stops to your exposure, fumbling with your phone, trying not to drop it in the water. Then more math to convert the seconds you came up with into the minutes the timer needs. Wait, how long did I say that was? Start over... Or is that just me? Long Exposure Timer makes it easy to calculate long exposures based on adding stops for filters or other adjustments and then just hit start to time your shot. All from your wrist, with no risk of dropping anything. New in version 1.1, film shooters can add reciprocity failure for popular film stocks from Agfa, Ilford, Kentmere, Kodak, and Foma. Long press on the interface to display the settings page, switch on film mode, and select your film stock. Note: Reciprocity failure adjustments are based on formulas provided by the manufactures or worked out from existing tables. We recommend running test exposures before doing any critical work, including at the exposure times you anticipate. Very long exposures may require additional adjustments.

PocketMeter Pro turns your iPhone into a professional light meter. Built for film photographers and cinematographers who think in stops, angles, and zones. Point it at a scene and get a live exposure reading, solved across real photographic stop tables. Lock any two of shutter, aperture, and ISO, and the third tracks the light in real time. Tap anywhere in the frame to spot-meter: the tapped area is placed at middle gray, exactly like a spot reading for shadows or skin. • Live scene metering read directly from the camera sensor • Tap-to-spot metering with one-tap return to full-scene evaluation • Lockable dials with a priority-aware exposure solver • Pop-up scrub wheels with haptic detents — it feels like a meter, not a form • Hold any reading while you work, then release to go live again • Over- and under-exposure warnings when a solve runs out of range CINEMA MODE • Shutter angle instead of shutter speed — 180° at 24 fps reads 1/48 • Frame rates from 23.976 to 60 • ND filters in cinema density notation (ND 0.3 to ND 1.8), right on the control deck — photo mode shows classic filter factors (ND2 to ND64) instead • False color, one tap from the viewfinder: an ARRI-style exposure map where green is middle gray, pink is skin key, and red is clipping — read relative to YOUR dialed settings, not the phone's auto-exposure ON SET, IN THE FIELD • LiDAR rangefinder: distance to your metering point in feet and inches (iPhone Pro models) • Live color-temperature readout in Kelvin from scene white balance • LOG: save a frame to Photos stamped with your full exposure — EV, shutter or angle, aperture, ISO, ND, white balance, distance — and geotagged, so you can swipe up later and see exactly where you metered it • Full portrait and landscape support with translucent controls that keep the viewfinder clear BUILT BY FILMMAKERS PocketMeter Pro comes from Studio C-41 and was built and field-tested alongside working cinematographers. Requires iOS 17 or later. Rangefinder requires a LiDAR-equipped iPhone (Pro models). Camera, Photos, and location permissions are used only for metering, saving your logs, and tagging them — nothing is collected or shared.
