- With that all explained, what does reciprocity mean practically for your long exposure photography? Essentially, it means that for exposures of 1 second or more you are going to have to make certain compensations in order to adjust to the film’s loss of sensitivity through the exposure. In other words, if you don’t add more time to your e…

- Reciprocity failure, also called the Schwarzschild effect, is the term used to describe photographic film’s non-linear response to low light exposure. What it means is that once the light levels reaching the film drop below a certain threshold, the effective sensitivity of the emulsion decreases.

- In short, reciprocity failure is how we describe film reacting unevenly to exposure. Usually, film's exposure is pretty linear: exposing film at f/2.8 for 1/60s will give you the same negative density as exposing at f/4 for 1/30s or f/2 for 1/125s. When you start to reduce the number of photons hitting your photosensitive material per second, though, things get a bit out of sync.

- Reciprocity failure is this really annoying thing in low light. What happens is the silver halide that site within that film actually needs a certain number of photons to hit it, for the silver to activate and cause a slight chemical reaction so that it's able to accept the developer to …

- The photographs that result from reciprocity failure in B&W film are of lower density with non-existent shadows. In color and slide film, you will see funky color shifts as a result of the uneven light reactions and the different ways each color layer reacts. The exact colors you will see will depend on the particular film you’re using.

- Reciprocity Failure: With digital cameras, reciprocity works fine except for the fact that noise can be an issue when aperture value is narrowed down and exposure times are longer. Long exposures can lead to digital noise which look more like grains in the film. With film users, reciprocity sometimes fails due to film reacting unevenly to exposure.

- The idea is that the same density is achieved, say, intensity I in one second and with half the intensity or I/2 in two seconds. Film does not strictly respond in this way. At extremely low light levels this is not strictly true – hence what …

- In simple terms, Reciprocity means, that when you expose your film to the light for (most of the time) longer than one second, the effect that the light has on the emulsion is reduced. Therefore you have to alter your exposure time to get a correctly exposed image.
