- POt = Pinhole camera opening time fp = Pinhole camera f stop number fd = Digital camera f stop number DOt = Digital camera opening time In our case the formula results: POt = ((230)^2/(16)^2)*(1/320) = 0.64 s

- For example, if the light meter which is set to f/22 gives us a reading of 1/30 second, the calculation for our pinhole camera with an f number of 138 would be (138/22) 2 = 39.3. The indicated time by the light meter has to be increased 39.3 times, resulting in an exposure time of 1.3 seconds. Free Pinhole Exposure Charts & Exposure Guides
DETERMINING EXPOSURE TIMES FOR PINHOLE CAMERAS
- https://www.pinhole.cz/en/pinholecameras/exposure_01.html
- This is done by dividing the f number of the pinhole camera by the f number set on the light meter; this number is squared and the result is used to multiply the measured exposure time. For example, if the measured exposure time for f 22 is 1/60 second, the calculation for our pinhole camera with an f number of 250 is: (250/22) 2 = 129. The measured time is increased 129 …

- Okay, on to the methods of finding exposure times… Method 1: Guessing. Yeah, guess. Open the shutter for some amount of time, develop the negative and if it’s underexposed (ie: the negative’s too white) then leave the shutter open longer next time. If the negative is too dark, then the exposure should be shorter next time. It’s that simple.

Exposure Guide | The Pinhole Gallery

- The ‘Seat-O-the-Pants’ Guide to pinhole exposures. First a little bit about the size of your pinhole relative to the size of your camera. I usually go with the rule of thumb that says that is your camera has a focal length of 6″ then your pinhole should be .5mm in diameter. This is a rough measure, but it gets you into the right area.
Determining exposures for the pinhole camera

- EV was 13.5 and exposure was 42s. Thanks to the assumption of reciprocity, the table can be used for other film or paper sensitivities. For example, some papers have a sensitivity around ISO 6 (one stop down from 12.5) so you will double the time shown. My favourite 4in x 5in cut film has an ISO of 25 (one stop up from 12.5) so I will halve the time.
