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?
Just downloaded and tried this photography app. I found this to be an easy exposure calculator when using neutral density filters. Enter the basic settings and the app will automatically tell you the time of the exposure. If the exposure is more than bulb (30 secs) the app will open a timer. I rate for 5 stars. However, its hard to find anything perfect because there is no such thing. But a new update could include an alarm for the timer. I thank and recognize the author for making this app and free for photographers and users. I'll look and follow him. This app is exactly what I was looking for and should help me using ND filters. Thank you again. 🙂
Does what is says without any fuss
Perfect app really. Simple and to the point. Essential to eliminate any potential errors in calculating exposure by yourself. I still shoot film, and it's nice to have assurance that I have the correct exposure while using filters.
