PinholeCam vs Pinhole Assist Usage & Stats

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.

Pinhole Assist

*** Feb 8, 2019 "My favorite pinhole app!! "This is my go to app for pinhole photography…this has made getting good results much easier…" bizzy *** Dec 16, 2016. "Wow. This app blew me away with its features and calculations (especially reciprocity fail). - Horacekenneth *** Feb 19, 2014 Wonderful!! "This app is perfect for the pinhole photographer in the field. I love that I can save settings for all my cameras and recall them instantly in the moment. - Papskier" *** So useful! May 26, 2013 "This takes the guesswork out of exposure calculation, since it turns your iPhone into a light meter and suggests the correct exposure! Works like a charm. Great app for pinhole photographers." *** May 16, 2012 : "Pretty much the perfect app for pinhole", Gavin Lucas *** March 26, 2012 "Pinhole photography - Great app! This will make pinhole photography much simpler to do", Zone v *** November 28, 2011 "Great solution !! - Thank you for this Pinhole timing app. I have many different pinhole cameras and this will help me figure timing on all of them. Thank you !!Greg." Pinhole Assist will be your companion to argentic and numeric pinhole, as well as view camera photography and wet-plate . The range of aperture and sensitivity (starting at 0.05 ASA ) allows for film, photo paper, wet-plate and as well as pinhole. * Built-in camera computes exposure; * alternatively enter EV reading for any lightmeter * or enter time metering to compute reciprocity effect. * Use built-in exposition timer and bubble level for optimal shot; * The light meter has a spot-meter feature and allows for incident metering; * Enter your camera aperture from the predefined list (170+ pinhole cameras) or compute it; * Let the assistant automatically compensate for reciprocity of film (correction for long exposures, 60+ different curves included), or use your own curves. * Save, restore and presets (combos) : aperture, predefined cameras, ASA and reciprocity settings • 30+ builtin filters (red, ND…), add your own, mafast acess your favorites , * Log shot information : preview, exposure, metering, location, interactive map , date and a shot. Export as picture, CSV or JSON file. You can create film and set reciprocity curve from within Pinhole Assist. Crete new ones, or tweak existing ones. Use iTunes (on Mac/PC) to import/export access the films you created, or exchange them via email m curves (Go to the app Web Site for instructions) * timer usability : now tapping the chrono icon directly starts the timer starting the chronometer automatically create a log. * Combos : edit for your camera+ film combination (combo) the aperture or the predefined camera, as well as film speed and reciprocity. * Choosing a film reciprocity now sets the film speed. * 100+ different films, including Multigrade paper and Harman positive paper * 300+ different pinhole and zone plate cameras : Ondu, Diana, Holga, Sténoflex, Reality soSubtle, Lensless, Ilford, Stenopéika, Vermeer, 8banners, ZeroImage, Leonardo, Carlos, Nopo, Spiral, Sharan… Any other camera can be accommodated. Go to the Settings to : * adjust scales can be by ½ EV or ⅓ EV, * enable bellow correction: a button will appear on the main screen to allow bellow adjustment, allowing to use view cameras; * adjust the cell and incident metering constant; * start the timer automatically or not; * adjust log behavior. Please note: this is not a camera app: it does not take picture. This is a sophisticated exposure calculator to take argentic (ou DSLR) shots with an pinhole camera.
