- Luckily the camera has a built in guide that allows you to match up a given exposure reading, say f/5.6 @ 125th of a second, and then read the correct time for the pinhole. Then you must take reciprocity failure into account. …

- The reciprocity failure properties of most films adds great flexibility to pinhole photo exposure. This image (which also appears at the top of this post), was taken shortly after I took a fall climbing down to the bank of the Columbia just outside of Astoria, OR.

DETERMINING EXPOSURE TIMES FOR PINHOLE CAMERAS

- 22 is 1/60 second, the calculation for our pinhole camera with an number of 250 is: (250/22) 2 = 129. The measured time is increased 129 times, therefore the exposure time for the pinhole camera will be 2 seconds (rounded). Reciprocity law failure (Schwarzschild effect)

The Comprehensive Tech Guide To Pinhole Photography

- The formula is; focal length = (pinhole diameter / 0.03679) 2. The focal length is the distance that the pinhole should be from the film. Example using 0.3mm pinhole: focal length = (0.3mm / 0.03679) 2; focal length = (8.17438) 2; focal length = 66.49mm ; The next value that needs to be calculated is the view angle of the pinhole.

- Yes you can use digital pinhole, however in my experience film’s greater latitude to underexposure and especially overexposure works perfectly with the pinhole’s long exposures. Another area that might seem daunting is composing without a viewfinder, figuring how to meter the scene and dealing with film’s reciprocity failure.’
[pinhole-discussion] Compensating Reciprocity Failure
- https://www.mail-archive.com/pinhole-discussion%40pinhole.com/msg09653.html
- Hi, Does anyone use ILFORD HP5 Plus sheet film for pinhole photography? If yes, I need advice. The manufacturer has supplied my with a reciprocity failure chart that end with 35 seconds metered time, transforming into 200 seconds actual exposure time. On my last shooting meter reading was 2 minutes.
Pinhole camera - Wikipedia
- https://en.wikipedia.org/wiki/Pinhole_camera
- Due to the large f-number of a pinhole camera, exposures will often encounter reciprocity failure. [19] Once exposure time has exceeded about 1 second for film or 30 seconds for paper, one must compensate for the breakdown in linear response of the film/paper to intensity of illumination by using longer exposures.

- In addition, reciprocity failure increases exponentially so that the longer the exposure the greater the failure. For example, an image requiring a 25 second exposure with the BW400CN will require an exposure of 150 seconds with Tri-X. This is a 5 times longer exposure for BW400CN but Tri-X requires an exposure 7.5 times longer for the same image.
