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

What does ND Filter Expert do?

With ND Filter Expert 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.

That's no problem. ND Filter Expert helps you get started with ND filters. The app gives you extensive information and simple step-by-step instructions on what a neutral density filter is and how to use it with your camera. In addition to the extensive tutorial, we offer you additional information and also give you recommendations for suitable accessories. Thus ND Expert 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 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.

Can I combine filters? 

Yes, of course, because ND Filter Expert gives you the ability to calculate the exposure time of up to five combined filters. For each filter you can choose from the total number of all filters (ND1 - ND19) and combine them.

We are a small two-man company and our apps are created entirely in our spare time. Therefore we use discreet advertising banners outside the main operation to reward the work on the apps a little. We put a lot of time, energy and love into these little helpers, to be able to provide you with the best possible result.
