About this app

The easiest and fastest way to calculate the exposure time when using neutral density filters or gray filters.

What does ND Filter Expert Pro?
With ND Filter Expert Pro you can calculate the exposure time super fast and easy if you use ND filters on your SLR camera or if you want to know which ND filter to use for your photo.

You don't know how to use ND filters?
That's no problem. ND Filter Expert Pro helps you get started with ND filters.

In addition to the extensive tutorial, we offer you additional information and also give you recommendations for suitable accessories. Thus ND Expert Pro offers you a complete package from start to finish for the use of ND filters.

calculating or writing it down?
Do you have all exposure times with ND filter in your head or do you always have to write them down? That's over now. Save the calculated exposure time as a favorite and quickly access it again.

Problems with measuring the exposure time ?
Do you also never know when the calculated exposure time is over or do you have to carry a stopwatch? ND Filter Expert Pro has a built-in timer function that allows you to measure times accurately over three seconds. The app notifies you with an alarm and vibration when the timer expires. In the settings you will find different types of tones and vibration schemes to choose from.
