Some Grey Arrows members may already have used my original ND Filter Calculator.

I’ve now developed a substantially updated Android version with a “built-in live light meter”. Instead of checking the shutter speed in a separate camera or light-meter app and then entering it manually, you simply point your phone towards the scene. The app measures the light and recommends the appropriate ND filter.

It includes:

• Live ND-filter recommendations  
• Live shutter-speed readings  
• Target shutter speed based on frame rate  
• White-balance guidance  
• Exposure calibration  
• A manual ND calculator

I’m looking for Android users to help with the required Google Play closed test. Testers need to join through a private Play Store link, remain opted in for at least 14 days and use the app a few times during the test.

The app is free, contains no adverts and requires no account.

If you would be happy to help test it, please comment below or send me a private message. I’ll send the testing instructions and link once everything is ready.

Many thanks,  
Paul

Hi Gerry

I think I may have missed you message. If I did, sorry.

Thanks for offering to help. If you let me have the email address that you use to log onto Google Play Store I will add you to the testing panel.

Thanks again for offering to help.

Cheers  
Paul

I would be glad to help.

I have several Android phones and tablets plus I can sideload onto Crystal Sky and RC Pro controllers if that helps.
