# Adjust Brightness

1. Click to trigger an image acquisition and automatically determine the exposure setting.

   By pressing the button, the exposure time is adjusted automatically to get the best image. Also, if you type a fixed value in the Exposure (ms) text box, you can set the exposure time (in milliseconds) for your image acquisition.

2. If needed, use the Light Control 1 text box to adjust the LED light intensity.

   Note: By default, the Light Enable check box is selected. If you clear the Light Enable check box, you disable the Light Control 1 option. The camera's LED light is turned off, and the camera is dependent on ambient (room) lighting.

Note: AlignSight only supports 2 exposure settings per camera; Features 1 + 3 and 2 + 4 share the same settings
