- 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 …

- 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.

- As light becomes more scarce, the silver halide grains residing in your film will be less uniformly struck by photons, causing a steep drop in density after a few seconds of needed exposure. This exponentially diminishing response to low light levels is more popularly known as a film’s reciprocity failure.

- Reciprocity Failure Okay, so this should make it clear what reciprocity failure is; in simple terms it’s when the aforementioned reciprocity breaks down and is, big surprise, a fail. This happens when you decide to take your camera for a night time walk, or whip it out in any other low light setting, and the shutter speed goes up to a few seconds.

- 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.

- What is "reciprocity failure". A failure of film to expose correctly after very long or very short duration shutters. For example, perhaps you figure out that a particular picture would take 2 minutes at f/16, but when you get the film developed it's underexposed. Or f/2.8 for 1/4000, but this is also underexposed.
