ND Exposure Calculator

Prepare a long exposure without calculating each filter separately. Combine your ND filters, include supported film correction and take the result into a timer. STACK FILTERS, CALCULATE TOGETHER Choose your filters and calculate their combined effect on the exposure time. INCLUDE THE FILM CORRECTION Supported ILFORD profiles provide reciprocity correction using retained manufacturer data. Other films are not automatically interchangeable. START WITH THE PLANNED TIME Move the calculated exposure into the timer. Save a setup to reuse on your next shoot. Calculations help you plan the exposure. Background timer delivery depends on the system and any required notification permission.
