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. * 119 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.
What's New
We regularly update and enhance the application, for better and nicer pinhole shots. New features and enhancements: * code optimization * new camera presets: Ranica Mir 35A, 7F, 9F, 9|6F and 12F 327 camera presets and 122 films available! If you don't find your favorite film or camera, contact us. We will implement it.

User Reviews
This app is great for metering, getting a view of the picture the pinhole makes, and incorporating reciprocity curves. Even works with slide film (which is known for being tough to meter). I recommend it to everyone. The only potential feedback I could give would be to match the zoom and shape) square vs rectangle) to the image size and focal length, and maybe to allow a “blurry” view to better anticipate what the pinhole camera might capture.
This is really the best pinhole light metering app out there, and I can’t knock it. I make my own pinhole cameras, and I need the option to manually enter my own f stop if it does not appear on pulldown list. Otherwise very well done!
Very helpful app for pinhole photos. The metering works well and it is easy to find and use aperture and film data. Timer helps a lot also. Good support, though I needed extra steps because developer uses Facebook for support. [I don’t like being tracked by Facebook and refuse to install or use it.] Developer responded quickly after I used my review to request support.
I’m relatively new to pinhole photography. Currently using Thingyfy lenses on my EOS 5D MKIV. I tried out this app for the first time today. With all parameters set correctly, I was able to get good exposures the first time. You have to covert the aperture diameters to f stops. Then you are ready to go. I was able to get good images with long exposures at ISO 100. Very pleased. Thanks.
Really like this app
I regret the 3 star review that I wrote in frustration when all my combos disappeared. This has been fixed and the communication has been excellent. This is a great app, so helpful for pinhole photography.
I really like this tool. It saves me the trouble of figuring out the exposure time given the small aperture of a pinhole camera. However, it does crash every single time I try to add a film (when I edit the reciprocity correction table). This is very annoying.
This is my go to app for pinhole photography. I just started playing around with pinhole cameras about a year ago and this has made getting good results much easier, especially because it takes reciprocity failure rate for whatever film you’re using into account. The only other option I wish it had was the ability to key in “normal” exposure settings from a handheld light meter or dslr test shots and convert it to your pinhole exposure settings. Regardless, this makes pinhole life soo much easier! Thanks for making this!
Thank you, Henry, for the regular updates with the constant additions of films and cameras. There is no other app I value more.
Love the app but it's odd that the picture used for the icon is NOT a pinhole camera. It clearly has a lens on it.
