Focusing Loupe

Use your phone as a focusing loupe!

Focusing Loupe is a user-friendly app designed to help you focus your large-format camera with ease. It lets you view the ground glass image either in its natural upside-down orientation or flipped to correct it. You can manually adjust the distance between your phone and the ground glass, which is particularly useful when light reflections interfere with automatic focusing. You also have full control over magnification levels.

This app is specifically optimized for Graflex Speed Graphic cameras with the focusing hood attached, where traditional loupes may not be ideal.
