Hyper Focal Distance Calculator
The HFD Calculator application has an intuitive interface, aided by Apple®'s user-friendly iPhoneTM platform.
The application has two functional screens:
1. Main Screen
The main screen allows the user to select the focal length and the aperture.
By selecting the icon at the bottom right of the main screen, the Camera & Units Screen is displayed.
2. Camera & Units Screen
The Camera & Units Screen allows the user to select the preferred measurement units and the camera type.
To return back to the main screen, select the button on the top right of the screen.
