Silverlog ND

Calculate corrected exposure times when using ND filters. Stack multiple filters and see the combined effect on your shutter speed.

Silverlog ND calculates the corrected exposure time when using neutral density filters, including stacking multiple filters together.

HOW IT WORKS Enter your base exposure without filters, then select one or more ND filters by their stop value. Instantly see the corrected shutter speed accounting for the combined filter density.

FEATURES • Single and stacked ND filter calculation • Common filter strengths (1-10 stops plus Big Stopper, Super Stopper) • Shows combined stop reduction • Base exposure input in standard shutter speed increments • Works offline — no internet connection needed • Clean, focused interface • Dark mode support

USEFUL FOR • Long exposure photography with ND filters • Waterfall and seascape smooth water effects • Motion blur in daylight conditions • Stacking filters for extreme exposures • Working out which ND filter to use for a target shutter speed
