Using Camera Controls

Camera controls are used during drop examination to adjust the way your images appear on the screen based on the light source being used.

The camera control panels are found under the Visible Image and Ultraviolet panes. The contents of the camera control panel vary depending on the imaging method you are using. There are two possible main camera control panels, as shown below.

Use the tables below as a guide to help you understand the various controls.
