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 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?
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!!
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. 🙂
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!
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.
Simple app that does get the job done. It would be nice to have an alarm on the timer though.
Does what it advertises to do perfectly. And free without annoying ads. Well done!I just want to ask for a loud buzzer at the end of a timer :)
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. Thank you!
Can’t figure it out, is there a tutorial?
