Exposure Time

Adjusts the time for how long the camera should expose the image and collects light from the sample.

Various arrows increment the time in a steady manner.

The

AutoExposure drop down button, located in the menu buttons, can be used for automatic exposure

settings. Select from:

Best (longer exposure): Exposes the image to the maximum value of the histogram (65,000 gray

levels).

Better: Exposes to fill the histogram 50% so the brightest portion image is at 32,000 gray levels.

Good: Exposes to fill the histogram to 25% or 16,000 gray levels.

Minimum (fast exposure): Exposes to fill the histogram to 10% over background.

Note: Minimum and Good settings are particularly useful for chemiluminescent imaging applications and

allow for quicker image capture overall.

Gain

Available only for some cameras.

Light Mode: When set to ’low’, the Anti-Blooming feature of camera is turned off. When set to

’high’, the said feature is on.

Gain: Set a high value for gain to get increased sensitivity. That also increases background

noise.
