Long Exposure Calculator

I have for many years now used Nisi filters as well as Lee and a few others. Lee and Nisi have their own apps but this is my go to app for calculating out the times. Simple and easy to use, just what you need when the light is changing fast. The functionality of this app is better than any others I have tried. Keep up the good work 😊

It works perfectly and has a very simple and intuitive interface. I would like to ask the developers to add an option to display the calculated time in seconds only. The new A7R5 has a built-in timer that accepts seconds only. It would must quicker to have the total time displayed in seconds so I do not have to convert minutes to seconds and then add the remaining seconds.

Everything I need, nothing I don’t. Demystifies a lot of the ND process and makes it very easy. Happy to pay the $3.99 to get it ad free. Thank you!

Can’t figure it out, is there a tutorial?

This app works very well as a long exposure calculator for novices in long exposure photography as well as professionals. The design of the app is great and everything is straight to the point. I am grateful for the lack of annoying advertisements. This is all I at least what I would expect in a paid app but for free. An alarm at the end of the timer would be nice, but I seldom use it. I use this app every time I take a daytime long exposure photo using a neutral density filter. It is far more efficient than a reference card or many other apps that I have seen. Overall, it is very simple, effective, efficient, and easy to use for photographers of any skill level. Although, I wish that it included aperture. Also, is the base shutter speed with or without the ND filter?

Simple app that does get the job done. It would be nice to have an alarm on the timer though.

This free app was made by a landscape photographer friend of mine who is very serious of his craft. Very simple to use and most importantly it’s FREE 🙂

This calculator is a great little app. Easy to use. Clean looking. Does the job perfectly. Thanks to the author for putting this out there!!

Simple and easy to use. Just what I need.

Exactly what I was looking for.
