Pinhole Assist for iOS


Developer's Description

** 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 pinhole and wet-plate collodion photography. The range of aperture and sensitivity (starting at 0.25 ISO) allows for wet-plate and slow processes as well as pinhole. Compute exposure time; Use built-in exposition timer and bubble level for optimal shot; Measure light : global measure or spot-meter; reflected or incident; Enter your camera aperture from the predefined list or compute it; Let the assistant automatically compensate for reciprocity of film (correction for long exposures, 16 different curves included), or use your own curves. ISO settings go as low as .006 ISO, allowing wet-plates sensitivity, and aged photo paper. Save and restore presets : aperture, iso and reciprocity settings Estimate light or measure it directly with the camera. Log all the information about a photography : exposure, metering, location, date and a shot. This information is saved as a picture uin the photo album.Many pinhole camera settings are already included : Zeroimage, Diana, Holga pinhole, Ilford/Harman Titan and many more ! You can create and modify reciprocity files from within Pinhole Assist. Via iTunes, you also can create and modify the reciprocity correction curves (Go to the app Web Site for instructions)Light measurement is only available on devices with camera. However, the manual setting allows you do do estimation with text indication, or use an external cell. Cameras predefined settings: Diana multi pinhole Holga 120 pinhole wide Holga 120 pinhole stereo Zeroimage 135 Zeroimage 2000 Zeroimage 45, +1 frame, plus 2 frames Holga 135 Pinhole Holga 120 pinhole Ilford Obsura Harman Titan 72 mm (basic) , 110mm, 150 mm Pinhole Blenders 135, 120, 4x5 including minis Leonardo 3" and 6" 8x10 ondu 135, 120 and 4x5 RealitySoSubtle 4x5, 6x17 and 6x6 Lensless 4x5 (50mm, 75mm, 150mm) and 8x10 (150mm)Any other camera can be accommodated. When using with a view camera with a normal (glass) lens, use the Settings apps to enable bellow correction: a button will appear on the main screen to allow bellow adjustment. Reciprocity charts included : A chart adapted from Jim Shull's The Hole Thing (the one I currently used for films) in two versions for easy editing Two chart for photo paper , A sample chart : Several charts derived from formulas by Gadget Gainer on APUG forums : 400TX,TMX,TMY,HP5+,100 Delta Several chart derived from formulas originating from Without Lenses website T max 400, T max 100,TRiX & Plus 125, Ilford films A chart for Ilford films. 5 charts for Ektachrome, Fujichrome, Agfachrome from "Using the View Camera". 3 charts for Arista film, courtesy of David Aimone Ilford Pan F, Fuji FP100, Fuji Neopan 100 ACROSBEWARE: this is not a camera app: it does not take picture. This is a sophisticated exposure calculator to take argentic (ou numeric) shots with an pinhole camera.

What's new in version 4.0.3

* now 68 different pinhole and zone plate cameras listed : added numerous pinhole cams : Nopo, 120 and 135, several zone plate from Zeroimage and more* distinguish from Ondu 6x12/6x6/6x6 pocket/6x12/4x5 Mark1 and Mark2 ondu pinhole : change in dimensions led to different aperture. Now both versions are list are listed* fixed a bug in the aperture computer : now give the correct value and units for optimal pinhole diameter
