Corrected Exposure Time

1.0 seconds

This is the adjusted exposure time needed to account for reciprocity failure in film during long exposures.

About Reciprocity Failure

Film becomes less sensitive to light during long exposures, requiring longer exposure times than calculated. Each film stock has different characteristics for reciprocity failure.

Minimal effect under 1 second
Significant impact on exposures over 10 seconds
May affect color balance in color films
