Very good app
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.
Perfect!
Everything I need, nothing I don’t. Demystifies a lot of the ND process and makes it very easy. Happy to pay the $3.99 to get it ad free. Thank you!
Tutorial
Can’t figure it out, is there a tutorial?
Great App!
This app works very well as a long exposure calculator for novices in long exposure photography as well as professionals. The design of the app is great and everything is straight to the point. I am grateful for the lack of annoying advertisements. This is all I at least what I would expect in a paid app but for free. An alarm at the end of the timer would be nice, but I seldom use it. I use this app every time I take a daytime long exposure photo using a neutral density filter. It is far more efficient than a reference card or many other apps that I have seen. Overall, it is very simple, effective, efficient, and easy to use for photographers of any skill level. Although, I wish that it included aperture. Also, is the base shutter speed with or without the ND filter?
Ok I got how it worked now :)
Simple app that does get the job done.
It would be nice to have an alarm on the timer though.
Simple, Easy,Straightforward, No Bullsh$t App.
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 🙂
