Lghtmtr is a beautifully simple light meter that helps you find — and understand — the ideal exposure settings for a scene. Built for film photographers and anyone learning the craft, it makes the relationship between ISO, aperture, and shutter speed feel intuitive and the visual feedback helps reinforce the connection between them. Take a reading, get your settings, and start exploring. Adjust one value and the others respond instantly. Lock settings to experiment and see how each change affects your exposure. You can easily add camera profiles to the app to limit the possible values to what's most relevant to your camera and lens combination. With a visual reference of the scene behind every reading, Lghtmtr helps you shoot with clarity and confidence.

Your old camera is full of photos you never pulled off it. The cable's gone, the card reader's lost, and the original app died years ago. Dig Pic brings them back. Wi-Fi import, no cable. Turn on your camera's Wi-Fi, point Dig Pic at its screen, and it reads the network name and password for you. Every shot flows straight onto your iPhone at full resolution — EXIF intact, no SD reader, no desktop. A real film darkroom. Dig Pic isn't a one-tap filter. It develops your photos with a colour engine built on real film characteristics: • Dozens of hand-built film looks — colour negative, slide, black & white, lomo and creative • Real film grain computed on the GPU, not a texture slapped on top • Halation (the red glow film leaves around highlights) and bloom • Crop with a straighten ruler, lens character, vignette, light effects • Date stamp like a 90s point-and-shoot Any camera ever made — via SD card. No Wi-Fi on that body? Pop the card into any reader, pick the DCIM folder, and Dig Pic imports straight from it — JPEG and RAW alike. The honest path that always works. Officially tested with the Leica C (Typ 112) and Sony RX100 VII. Other Wi-Fi-era Leica (D-Lux / C-Lux / V-Lux), Wi-Fi-era Panasonic Lumix (the Image App generation) and Sony "Send to Smartphone" bodies use the same radio and are expected to work — we're expanding tested models with each update, and the SD card path covers everything else. Private by design. Everything happens on your iPhone. No accounts, no tracking, no cloud — your photos never leave the device. One-time purchase. No subscription. Dig Pic is an independent app, not affiliated with or endorsed by Leica Camera AG, Panasonic or Sony. "Leica", "Lumix" and "Sony" are trademarks of their respective owners, used only to indicate camera compatibility.
