Extremely helpful and useful tool

Hooray! An easy-to-understand app taking the edge off a complex learning curve. The app has excellent help sections that are helping me better understand photography with neutral density filters. I really like the customization to my particular camera, lens(es) and filters. They have done great job with the graphics and functionality. Well worth the investment of money and time!

Best photo app for long exposures

I recommend this app for long time exposures using your DSLR camera. The have a great customer service too if you need to add a new camera to the app.

Needs a better lens database

For $5 it's pretty lacking, there is not one Minolta lens either. You can request lenses via email but I wouldn't hold your breath. It should at the very least allow you to add in your lenses manually, and enter the specifications yourself if it's not in their database.

In the info section it offers links for tips for taking pictures of the moon and such, it would be much better if the tips were in-app or at the very least, the links open in Safari View Controller so it doesn't pull you out of the app.

Native iPad support would be nice as well.

But it is well designed and looks nice, unlike most other dslr guide/calculator apps. Apple Watch integration is always a plus as well.
