A tilt-shift lens allows to move the plane of focus at will within the boundaries of the lens' settings. Tilt Calculator determines the best settings of your tilt-shift lens so you can adjust it accurately, and get the focus precisely where you want to! No need to carry printed charts, tables etc. Say also goodbye to blindly fiddling with the lens tilt. Get the app, bring your iPhone, input your settings and you're all set (see Note)! This app not only puts you back in control of your lens, it also helps you understand what is happening.

The Tilt Calculator app was designed such that it can be used reliably with just one finger. Having taken many photographs in the middle of winter (up in Finland) in temperatures colder than what your deep-freezer can do, we know the importance of keeping one's hands warm :)

Tilt Calculator contains simple explanations of the plane of focus, its angle, of the hinge line and how these change with the lens tilt and the focusing distance, so you know what affects what. "Blueprints" also illustrate the basics.

Importantly, the app also takes into account your camera tilt, for it is an important part of a photographic composition e.g. in landscape photography. The camera tilt can be set manually or measured automatically!

Tilt Calculator also contains a spirit level: accessible from the main screen with a 2-finger tap, the spirit level allows you to accurately adjust the head of your tripod to a level position prior to installing your camera. (Exit the spirit level using a 2-finger tap as well).

We welcome feedback and suggestions! You can send in-app email directly :)

Note: we decline responsibility should you forget your tripod, camera and/or tilt-shift lens :)
