DFC Twain Overall Design

Layout The Leica DFC Twain user interface looks similar to the

screenshot below.

The camera Control Panel is on the left, and the camera

Live Image is on the right.

The active camera name appears in the DFC Twain title

bar at the top.

The Control Panel handles all the operations of the

camera. Some controls are also available within the

Live Image area.

The basic camera functions are contained in the upper

section of the control panel. These include controls for

exposure, color, contrast and image acquisition. The

live image histograms, showing the light intensity

across the live image, are also displayed here.
