myLightMeter PRO vs PinholeCam

Designed by a photographer, for photographers. Built for reliable, precise exposure measurement across film and digital workflows. myLightMeter PRO gives you full control over exposure through a clean, professional set of tools. Key Features • Incident and reflected-light metering • Classic and Pro interface styles • Full manual control over aperture, shutter speed, ISO, and exposure compensation in 1/3- or 1/2-stop increments • Exposure range from 4 hours in Long Exposure mode to 1/8000 s, f/1.0 to f/512, and ISO 0.8 to 409,600 • Aperture-priority (Av) and shutter-priority (Tv) modes • Automatic ISO adjustment or ISO lock • Reciprocity correction for long film exposures • Sensitivity down to −2.5 EV, ideal for low-light scenes • Average multiple readings • Import shutter speed, aperture, and ISO from photos in your library • Organize readings into Sessions with photos, exposure data, camera and lens details, and notes • Keep your Sessions synced through iCloud, so they remain available when you switch phones or use another device • Export Sessions as PDFs or print them Advanced Tools • Hyperfocal-distance calculator • Five configurable presets, each storing camera, lens, ISO, filter, and film settings • EV display with an analog scale or numerical reading • mySPOTMETER and f/Tools integration About This app is built and maintained by an independent photographer and developer. It is the tool I personally use and continuously refine. If you have suggestions or need support, contact me at: davidquiles@me.com

Note: Version 3 is a complete rewrite of the app. The simulation will not be exactly the same as older versions, and it is still evolving so watch for updates. Some features are limited for now. Feedback is welcome! Pinhole uses a unique method to simulate the long exposure times of a pinhole camera. It does not just simulate the distortion and visual effects, it gradually exposes the scene over time like a real pinhole camera allowing effects not achievable in other “pinhole” apps or regular camera apps. Unlike a real pinhole camera, all photos are automatically exposed correctly no matter the exposure time. It can optionally simulate the vignetting and/or edge light bleed typical of pinhole cameras. Exposure time can be set to one of several presets, or it can controlled manually for shorter or longer exposures. At any point, choose an “emphasis” image that will dominate the final output--use this to freeze a moving item in the shot (this feature is experimental and the outcome varies widely based on the scene). Saves directly to your camera roll. Load images to Facebook, Twitter, Flickr, Instagram, Camera+, etc. from there. Note: the simulation is very memory-intensive, especially on long exposures. For the best stability please close other apps and disable networking to prevent incoming calls and push notifications (put it in “Airplane Mode”). For best results, plug in your phone before beginning a long exposure. On the "infinity" time setting, it will run until you stop it manually, it crashes, or the algorithm used runs out of memory. It will attempt to close the shutter prior to crashing due to running out of memory, but it's not always possible to catch this. Your mileage may vary -- if you're considering taking an important long-duration shot, plan ahead and run a test on the device you'll be using. A note about the simulation accuracy: Pinhole does not have infinite depth-of-field like a real pinhole camera. The primary way this app simulates a pinhole camera is by allowing for very long exposures and simulating the visual effects. The simulation is as close as the hardware allows. Since an iOS device's camera has a lens, it is not possible to simulate a lens-less camera perfectly. If I could bypass the physical limitations of the hardware, I'd be filing patents for the technique and making a lot more money than I do selling an app. :) If this is critical to you, use a real pinhole camera or choose scenes where depth of field effects are not apparent.
