Wheel turns but bug stops you from selecting. ### 1/5 — Don't Get It *2015-08-22, version 1.1* I'm not sure why others say this is easy. It's actually to simple and does not have any explanation. The little it has is not well written. I think I wasted my money. ### 4/5 — So simple *2013-07-06, version 1.1* I tried a few calculators for nd filters and they were a little confusing. This is so simple. Take a reading with a light meter, then find out what the exposure should be with your nd filter. Done! ### 3/5 — Not Sure *2013-03-12, version 1.1* I haven't used this in the field yet, just down loaded it. I would have given a better rating if the ND Filter title bar was stationary so when scrolling down the filter size was always in sight. ### 5/5 — Simple and Easy *2013-02-15, version 1.1* A well designed straight forward chart. ### 5/5 — Awesome!! *2012-11-21, version 1.1* Awesome app. Easily explained in charts, I use 3 ND filters & CPL and I like shooting long exposure during daylight such as moving skies, etc so I need to use Bulb mode. Calculating how long to keep the shutter open can be a PITA so that's why this app is helpful. No need for any calculation, just have your camera meter the scene and all you need to do is compensate the time you need using this chart to keep the shutter open depending on how much stops of ND filters you stacked. ## Frequently asked questions about NDFilter Calculator&Sheet (Long Time Exposure Photography) ### What is the price of NDFilter Calculator?
