- 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.

- No, there is no reciprocity failure effect in a digital sensor. Reciprocity failure in film refers to the effect where the response of the film is no longer linear at long exposure times. In contrast, the response of a digital sensor remains consistently linear across its entire usable range (up to the maximum charge handling capacity of the pixel).

- 35. 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.

- Show activity on this post. In analog photography (film) there was an effect called "Schwartschild effect", or Reciprocity failure when making long exposures (usually more than few seconds). Some film brands created compensation tables for their films; for instance, you would need to double the time after 4 seconds, meaning if the meter says f/5.6 at 5 seconds you have to …

- Reciprocity failure is not a problem with digital cameras, however noise can be. Bad news for digital camera users Long exposures on digital cameras can produce visible noise, which looks a bit like the grain you see in a fast film image. This noise or grain is usually most noticeable in plain areas of the picture.

- 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.
