I use a spot meter, convert the result on the back of the pinhole and add the reciprocity failure from a chart on this web site,

Handheld Lunaix meter, ambient reading, never had a problem.

I've never understood the hit or miss or suck it and see approach to photography. I dont get the motivation or indeed the point of going to the 'trouble' and expense of loading a camera with film, travelling, finding a shot, setting it all up then processing and printing the film while thinking that the basic principles of photo science have somehow been suspended and dont apply. Where does the creative energy come in if its just left to random chance? Exposure of film and the law of reciprocity should hardly be considered optional. Isnt it more artistically satisfying if the nature of the materials and the photographic process is understood first to put you in a position to then go on to work with creative power rather that hit or miss random chance? Isn't photography an art form after all?
Each to their own of course. |

Can not some of that ramdom chance be part of the creative energy?

I use mostly Foma100 in my 5x4 pinhole, it allows me to relax and avoid the hassle of dealing with exposure. That material has so bad recoprocity failure that anything at 0.5 sec = 1sec, at 1 sec = 10 sec, and at 10 sec = half an hour exposures. Ideal for a pinhole, and i you keep the above reciprocity on your mind, stick to the rule the longer exposure, the better, you do not have to measure anything, and will never end up with an underexposed negative.
Therefore, no hit & miss attitude, and still a creative freedom via focusing on the shot, not the laws of physics.

If I want consistent predictability from my photography I'd go out and buy a digital camera... each to their own of course. ;-)

Random chance is great. Ive been lucky once or twice but I wouldnt promote it over understanding the materials. If you expose and develop the perfect negative by random chance it only means that you accidently landed on the laws that govern photography. Last edited by kev curry; 12th March 2013 at 09:39 AM. |

Its never random chance.
Random chance is a picture timed to produce something between completely black and completely white. Since there is infinite opportunity to produce black or white, the "corridor" of exposure that qualifies as a successful exposure to the shooter, is really quite small comparatively, thus there will always be educated guesswork involved, not random chance imo. Your definition of successful, educated and the width of your corridor in this context, is subjective.. |

This is an expensive approach, but my Sekonic L758D spot meter can meter down to f/152. The next up is f/128, which is close to the alleged f/133 size of the pinhole in my Holga WPC120 pinhole - but I guess that Holgas' have some variability from the claimed pinhole aperture.
I've taken to using Acros to reduce reciprocity issues. I still find however that the "keeper rate" is much lower for my pinholes, than when using a lens
