B+W ND Calculator App
Essential calculator for landscape photographers
The length of exposure time can be determined easily using the new app "B+W ND-Calc". By turning the outer ring on the display, the exposure time measured without a filter is transferred, then the density of the grey filter used (ND value) is set, and the result of the corrected exposure time is immediately available.
The B+W app includes a timer with which the exposure time can be monitored after 4 seconds by pressing the inner ring (Bulb camera setting).
The B+W ND Calculator app is available for Android and iOS. It is ad-free and can be downloaded from the Google Play Store and the App Store.
