SDTravel,
Great app
I recently invested considerable sum into the Lee filter system for my Nikon D850. This app is a perfect match, allowing me to quickly calculate proper exposure for various filter combinations. While I have yet to shoot in the field since getting all my filters, I've played with the app enough to know it will be quite handy. It also got a recent update, so its nice to know development is active.
Kjljxybr,
Must have!
Not just a calculator. Excellent multitool with lots of professional tools for many photo/video needs. Important - each instrument has own very informative and helpful HELP menu, as well as a learning base. Beside that - quick, professional and friendly customer support. Highly recommended and huge respect to authors and developers!

Nature Photographer’s Adventure Guide
Want to photograph star trails? You need to know the settings for your camera. This app is where you will find them. An intuitive interface gives you the calculations for all kinds of nature subjects such as aurora photography, and lunar imaging. Now all you need is a reliable camera, proper clothing, and a sense of adventure.

Highly Useful App
No serious landscape photographer should go on a shoot without this app. It takes the mental gymnastics out of calculating camera adjustments necessary to achieve the best creative results using ND filters and long exposures.
Azankino,
Great app
This app is great for any novice that needs information on shooting anything you can think of. It has full tutorial on how to use your filters. Something I never find online.
The app is fully extendable and capable for any situation. It maybe a heavy price for some but add in the tutorials and information this would easily put the value higher but everything is at your finger tips.

Great application
I am professional nature and landscape photographer and this application is must have for me. I often use it for caculating exposure for star trails images and still stars too. I don't use ND filters but ND grad filters calculator is also very usefull. Other strong side of the app - very good documentation and great library of usefull links on photography resources.
JimW42,
Timer doesn't work in the background
This would be 5 stars if the timer would work in the background. But if you switch to a different app, or the iPhone goes to sleep, the timer stops!
So you can use this app to calculate the exposure, but use the iOS Clock app (which includes stopwatch and countdown timer) to time the exposure. Works great, and you can check email or put the iPhone to sleep, and timer keeps running.

A very handy tool
This is a great tool to use for night photography and blurred or frozen motion. Goes into great detail to explain how to capture stars across several popular techniques. I love this app.

What were they thinking
The older version of this app was simple and such a joy to use. The new version is complicated and convoluted, must have been designed by an engineer and not a user. Some features and info are nice additions, but the New interface is a downgrade in my opinion. None the less, thanks to Lee Filters for even having an app, It does make life easier.
Carlos san miguel,
Problem with timer
There is a problem with the stacked flters timer, when the iPhone goes to sleep, the timer stops working, it should keep working in the background and wake the phone with the 20 sec waening.
