Reciprocity Law Failure

EEUS-01006 - USA, Montaña de Oro SP (CA), Waves crashing on rocks

Below is a table summarizing the Reciprocity Law Failure values for the films that I normally use.

As you may know, for every type of film Reciprocity Law Failure occurs when photographs are taken with long exposure times. Under those circumstances, you need to dial in a certain exposure compensation value for your photographs to be properly exposed. The table below provides recommended exposure compensation values for different exposure times.

Please note that the information in the table below has been gathered by (and is the courtesy of) Fuji's and Kodak's Web Sites.
