  A Google User: Good and easy apk Does not include a EV calculator, so you can choose the shutter speed mentioned in the camera, select the ND filter, and receive the corresponding equivalent shutter speed.

  Leo Bounds: Very helpful I use this apk regularly and it's very helpful calculating correct exposure. Only negative is I sometimes hit some times not accessible in the apk but I create a guess and experiment

  Chris Gibson: Simples This is a no frills nd calculator and is exactly what I was after. For those having problem; 1) choose the nd filter in the left column 2) choose the shutter speed your camera is saying to use without the nd filter on your lens from the right column 3) the calculated shutter speed is shown at the top of the screen with the filter chosen and non filter shutter speed shown just below. Can't receive much easier or simpler then that!

  A Google User: Time saver! A excellent apk for someone who wants to receive the math done quick. The only thing that should improve this apk is half-stops.

  David Swager: Nifty apk that would benefit from a tiny Human Factors modernize This is a little, fast and usable apk. There are 2 recommendations I would create to the author for improvement based on my expertise in Human Factors Engineering and Human Reliability Analysis. 1. As photographers we all work in stops and the apk does present stops for all filter factors. However, there are 2 methods ND filters are specified by filter factors of 0.3, 0.6, 0.9, 1.2, etc. which equates to 1, 2, 3, and 4 stops of exposure reduction. Some manufacturers specify their filters with a filter fact such as ND 2, ND4, ND8, ND16, ND32, etc. which equates to 1, 2, 3, 4 and 5 stops. It would be helpful for some to have this filter factor specified in addition or as an option that should be set. 2. The another problem is more fundamental. The apk shows a scrolling list of filter factors side by side with a scrolling list of shutter speeds. My initial assumption was that you lined up the shutter speed with the filter factor and it would give the reply. However, what you actually do is tap the filter factor and tap the shutter speed. Unfortunately, the apk doesn't present you which filter factor or shutter speed is chosen in the list.

  George Nagy: Nice and easy apk Can you add every another stop from 10 to 20 We usualy stack up to 2 filters For example 10 + 6 will give you 16 10+2 will give you 12 etc.. Thanks and take care

  Ben Merigan: Easy and effective but.. My filter is labelled as ND4, but in your apk I think it is listed as ND0.6. This is a bit confusing. Another than that confusion the apk is very usable and does it's job well.

  Josh Levinson: Fine It's an fine apk. It does what it's supposed to ok, but the interface isn't too interesting. For some reason, it's also missing some shutter speeds (e.g. 1/800), which is annoying.

  A Google User: Good but Needs to be an option for 11, 12, etc stops instead of jumping from 10 stops to 13 for those who stack multiple ND filters.

  A Google User: Works well, but confusing UI This apk is easy and does exactly what I expected from it. But, I found the UI to be rather confused, when all I really wish is a easy list showing the shutter speed before/after applying my filter.

  Pablo Andrade Mejía: A little error to be corrected For some reason when I scroll on both shutter speed and ND filter column they go white making it impossible to read. Plus the top part that shows the final shutter speed is really dim. Please fix this. Sony Xperia ZL on Android device 5.1.1

  A Google User: Some bugs... ! There is 2 times "6 stops" in the left column and the calculation is not always accurate. For example if I begin with 1/1000 sec., for 7 Stops I receive 1/4" that is fine, but for 8 Stops I receive 0"4" (???) , for 9 Stops I receive 0"5" (???).
