You know the time without the filter -how long do you need to exp. WITH filter? Sounds easy but tell me quickly how long to exp. with an ND ①.⑧ if the time without filter is ①/③②⓪?
Now you can!
Set Filter and exp. time without the filter and you can see the correct time. In the example above ①/⑤
Even easier it shows you ⑤ because this is what you can set on a dSLR. Smaller letters showing you the actual time. For ①②⑤⓪⓪'' it shows, that these are ③h, ②⑧m and ②⓪s.
For times of ④+ seconds you get a countdown button to easily stop longer exposures manually with a remote shutter release with alarm and vibration (if supported).
