CalcuLight is a powerful and intuitive light meter app designed for today's film photographers who want more advanced metering capabilities than what a handheld light meter can offer.
METERING MODES
Center Weighted: Classic center focused metering (approximately 30 degree field of view), similar to vintage film cameras.
3D Matrix: Full frame averaging for tricky scenes. Uses your iPhone's extensive EXIF data for fast and accurate readings.
Spot (Pro): Measure a precise 5% area of the frame. Tap anywhere to position the metering point.
Calculated (Pro): Tap up to five areas and receive an averaged exposure reading. Ideal for high contrast scenes and Zone System workflows.
EXPOSURE CONTROLS
Shutter Priority: Set your shutter speed. CalcuLight calculates the aperture.
Aperture Priority (Pro): Set your aperture. CalcuLight calculates the shutter speed.
EV Compensation: Per shot exposure adjustment in full, half, or third stops.
ISO, shutter, and aperture (Pro) values are available in full, half, or third stop increments.
ZONE SYSTEM VALUE DISPLAY (Pro)
When enabled, displays Zone System value overlay, showing the current zone from O to X alongside your reading.
In Calculated mode, each metering point displays its own zone value for advanced exposure control.
LIVE HISTOGRAM (Pro)
Real time RGB histogram overlay to detect clipped highlights and blocked shadows before you shoot.
Toggle between combined RGB, red, green, and blue channels.
LOG BOOK (Pro)
Save every reading with full exposure data, metering mode, GPS location (Choose precise or general) and timestamp.
Notes area will be pre-populated with captured values in Calculated metering mode.
Easily export your shooting log as CSV or JSON. Ideal for tracking exposures alongside film rolls.

New Exposure Combination Scale Display!
The main readout now shows a scale of equivalent exposures instead of a single pair. Your current setting sits in the middle, underlined, with nearby combinations on either side so you can see at a glance that 1/125 at f/5.6 gives the same exposure as 1/250 at f/4.
• Swipe across the values to scroll through combinations
• Tap any combination to jump straight to it
• Combinations your camera can't reach are flagged
• Computed values now follow your own stop increment: a full-stop aperture setting gives full-stop apertures, even with the shutter set to ⅓ stop
• More reliable Remember Settings restore when the app launches
• Improved metering speed and smoother dial control
• Layout fix for the bottom controls on smaller screens
• Improved low-light accuracy
• cd/m² readings have been corrected to the ISO 2720 standard.
