Reciprocity law failure is a phenomenon that same amount of exposure (irradiance multiplied by duration of exposure) produces different image density when the irradiance (and thus duration) is varied.
There are two kinds of reciprocity failure. They are both related to poor efficiency of utilizing photoelectrons to create latent image centers.

Famous quotes containing the words reciprocity, law and/or failure:
“Between women love is contemplative; caresses are intended less to gain possession of the other than gradually to re-create the self through her; separateness is abolished, there is no struggle, no victory, no defeat; in exact reciprocity each is at once subject and object, sovereign and slave; duality become mutuality.”
—Simone De Beauvoir (1908–1986)
“Revenge is a kind of wild justice, which the more a man’s nature runs to, the more ought law to weed it out.”
—Francis Bacon (1561–1626)
“Extemporaneous speaking should be practised and cultivated. It is the lawyer’s avenue to the public.... And yet there is not a more fatal error to young lawyers than relying too much on speechmaking. If any one, upon his rare powers of speaking, shall claim an exemption from the drudgery of the law, his case is a failure in advance.”
—Abraham Lincoln (1809–1865)
