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.
