*** 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."

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
* 250+ 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.

Absolutely fantastic for Pinhole!

Jesse Holland on

I've used this app for a couple years now, and have seen many improvements over time. The combination of having a whole lot of camera presets built in, along with reciprocity failure calculation for a huge list of films, there's not really anything more I could ask to add. This is an absolute must have app if you're serious about nailing exposure in some tricky situations. Very, very flexible and adaptable to just about any scenario!

Very useful

KO6JW on

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.

Works great.

Really like this app

Great support!

sisHunter on

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.

Great tool

Howard Pan on

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.

My favorite pinhole app!!

bizzzy on

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!

keeps getting better

PibaHolga on

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...

zrb123 on

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.

Wow

Horacekenneth on

this app blew me away with its features and calculations (especially reciproc fail). I've been using it alongside a pinhole I made in a paintcan and (with the exception of one tricky lighting situation) all my exposures have turned out beautifully Now Im using it as just a regular light meter, still five stars

THE BEST !

ThenCameNow on

Absolutely the best app for pinhole photography. I love the option to save the view with all exposure data and time stamp. Bravo!
