Description

From the listing uploaded by “erasylgames”.

Most cameras today can't detect proper exposure through the ND filter so the process to take a photo with a ND filter is (Nikon camera example): 1. Switch to M mode (or S) 2. Find proper exposure without the filter 3. Put the filter on 4. Dial shutter speed to the value ND Filter tells you 5. Take a shot! The formula we use to calculate the values is Tnd = T0 * 2^nd, where Tnd is shutter speed with the filter, T0 is shutter speed without the filter and nd is filter density (1, 2, 3, ... 13). Code for the app is available at https://github.com/nciric/NDFilter.

ND Filter APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is the ND Filter APK safe?

No one can promise that a file is safe, but some things can be checked. The source store flagged this file with a security warning. After downloading, check that the file's MD5 is 231ebe80d8509d79f2704af62263ccf0.
