CineLoupe vs EV Calc

CineLoupe is a cinematographer's viewfinder that reproduces cinema camera sensor modes and lenses on your iPhone — including the bokeh. BOKEH YOU CAN SEE Using the iPhone's LiDAR (or stereo) depth, CineLoupe computes depth of field from the chosen focal length, T-stop and focus distance and blurs the live image accordingly. Tap to focus. Anamorphic lenses render with the correct squeeze and oval bokeh. SENSOR MODES, NOT JUST CAMERAS Crop by the actual imaging area of each recording mode — ALEXA 35 4.6K 3:2 Open Gate vs 4K 16:9, VENICE 2 8.6K 3:2 vs 5.8K 6:5 anamorphic — for ARRI, SONY, RED, Canon, Blackmagic, Nikon, DJI, FUJIFILM and more. A LENS LIBRARY THAT MATCHES THE RENTAL FLOOR 165 series and 1,400+ lenses: ARRI Signature / Master / Ultra Prime, ZEISS Supreme, Cooke S4/S7/S8, Leitz, Angenieux Optimo, FUJINON Premista, Canon Sumire, SIGMA, DZOFILM, LAOWA, Tokina Vista and many more. Browse prime / zoom → mount → series → focal length, or type any focal length and T-stop manually. FRAME LINES, AS MANY AS YOU NEED Overlay 16:9, 2.39, 9:16 or any ratio and percentage on the open gate at once, with optional outside shading and burn-in. TAKES THAT BECOME THE SCOUT REPORT Stills (HEIC) and video (HEVC / H.264 / ProRes, 1080p / UHD, Apple Log) with camera, mode, lens, focal length, T-stop, focus distance, time, GPS, heading and scene/take burnt in. Mark OK takes and export a PDF with maps, shooting order, sun position and a location checklist. Optional auto-upload to your own Google Drive or Dropbox. RE-SIMULATE LATER Stills keep the raw frame and depth map, so you can revisit a take with a different camera, lens, T-stop or focus and save it as a new take. SUN POSITION Sun azimuth and elevation overlaid on the finder, scrubbable through the day, with sunrise, sunset and golden hour. Requires iPhone 12 or later. LiDAR (Pro models) gives the best depth; the ultra-wide camera extends the wide end. Simulations are optical approximations and do not reproduce distortion, vignetting, cat's-eye bokeh, breathing or color of real lenses.

EV Calc shows, at a glance, how much a change in your camera settings affects brightness, measured in stops. Store your reference exposure with "SET", then turn the shutter, aperture, ISO and ND wheels. The difference from your reference appears large at the center of the screen, such as "+0.7" or "-1.3". Use it as a guide for how much to compensate after adding an ND filter or changing aperture or ISO. KEY FEATURES • Four wheels for shutter, aperture, ISO and ND filter • "SET" stores your reference exposure and shows the difference in stops (positive is brighter, negative is darker) • Color coding: your reference value in green, brighter options in orange, darker options in blue • Reference EV and current EV are always visible • Shutter angle shown like "1/48 (180°)". Choose the frame rate from 23.98, 24, 25, 29.97, 30, 50, 59.94, 60 or 120 fps, or turn the display off • ISO step: 1 stop, 1/2 stop or 1/3 stop • ND filter unit: density (such as 0.3), ND number (such as ND8) or stops (such as 3 stops) • Remembers your last settings and resumes where you left off • Landscape-only, dark-mode interface that is easy to read on set • No account and no network connection required NOTE Displayed exposure differences and EV values are theoretical. Actual exposure may differ depending on your camera and lens. Please use them as a guide.
