EquiCapture vs ProFilm Meter

EquiCapture is the ultimate tool for equestrian photographers. Whether you're capturing horses in motion or posing riders for portraits, this app keeps everything you need right at your fingertips. Features include posing inspiration galleries, horse whinny sounds to get a natural reaction from your subject, camera settings guides, affirmations, creative ideas, and meditation & prayer to center yourself before a session. Plus, get the latest tips and tutorials from Shelley Paulson Education.

ProFilm Meter is the most complete light meter and exposure toolkit for film photographers. From 35mm to 8×10 large format, dry plates to tintypes, it handles every calculation you'd normally reach for three separate tools to solve — all offline, all in real time. LIGHT METERING Your phone's camera becomes a precision reflected-light meter. Choose spot, center-weighted, or average metering and dial in exposure with ⅓-stop, full-stop, or any combination of increment sets running simultaneously. A live RGB histogram keeps highlight and shadow zones in view at all times. Native per-frame ISO, shutter, and aperture capture at ~10 fps Multi-point metering: average 2–4 scene readings into one exposure value Tap-to-focus and multi-lens camera selection Adaptive EV smoothing adjusts for scene changes automatically Screen stays awake during active metering sessions CALIBRATION Two-point guided calibration locks each camera to a trusted reference. After calibration, a fine-tune step lets you match any external meter in ⅓-stop increments. Uncalibrated cameras are gated with a full-screen prompt so you never shoot on an unmeasured body. FILM STOCKS & RECIPROCITY An on-device film stock library covers 35mm, 120, and large format emulsions — including the full Zebra Dry Plate collection. Every stock carries its own reciprocity profile. Eight built-in profiles (Acros II, T-Max, HP5+, Portra, Fomapan, Zebra, and more) plus full custom profile creation, including Schwarzschild p-factor and optional threshold. Add custom film formats and reciprocity profiles inline, without leaving the film stock screen. COMPENSATIONS Reciprocity failure — corrected automatically for exposures beyond threshold Bellows compensation — calculated stop-for-stop from draw and focal length RA4 Color Reversal — estimates scene color temperature and gives you Mired-shift filter corrections for color positives; works in both ambient and flash mode Spectral sensitivity — metering coefficients adjusted for panchromatic, orthochromatic, and blue-sensitive emulsions Lens filters — ND (1–10 stops), polarizer, yellow/orange/red/green contrast filters, R72 and deep IR, plus custom filters Positive/reversal process — +0.5 stop compensation, auto-enabled for tintype stocks UV/environmental compensation — adjustable for altitude and atmospheric conditions IR Light Estimator — dedicated tool for infrared exposure estimation FLASH Flash metering detects incident flash via fast polling with peak-hold and sticky arming. A built-in flash trigger supports Optical Slave (fires the LED torch to trip slaved units) and Cable Sync (audio click for USB-C to PC-sync adapters). VIEWFINDER A lens-independent viewfinder zoom gives consistent framing regardless of which physical lens the phone uses. Overlay your chosen film format frame lines and compose like you're looking through a director's viewfinder. FIELD JOURNAL Save any exposure to the journal with one tap. Each entry records ISO, aperture, shutter speed, EV, reciprocity correction, RA4 and spectral corrections, GPS coordinates, and a cropped preview photo. Entries are exportable and shareable.
