Example sentencesExamples
- Now if you have read about time exposures you will have come across the phrase ‘reciprocity failure’ with long time exposures.
- I've always thought this was a deliberate affectation, the result - in the case of photography - of six years of art school spent learning about reciprocity failure, platinum printing and other arcane chemistries.
- Those of you who have read books and magazines will have read about ‘reciprocity failure’ with long time exposures.
- The next fact is that you also do not need to know anything about shutter speeds, zoom lenses, reciprocity failure or the like.
- There's something called reciprocity failure which basically means that for exposure times above 1 second, the film takes longer to do what it should be doing and as a result, interesting qualities of light and shade develop.
