Imagers
Focus and Aperture: Press the Focus and Aperture
button to access lens focus and aperture adjustment.
Use the vertical slider bar and/or the "+" and "–"

Capture Mode: Press the Capture Mode button to
access exposure time adjustment for live image
preview and capture, as well as to select modes for
image capture.
Use the vertical slider bars and/or the "+" and "–"
buttons to make adjustments to the desired portion of
the exposure time (min, sec, ms or microseconds).
To adjust capture modes, select the desired mode
from the drop-down menu. Capture modes include:
 Manual Exposure: Captures one (or more)
images with a pre-selected exposure time.
 Auto Exposure: Captures an image with an ideal
exposure time determined automatically by the
system prior to image capture. (NOTE: When using
the Auto Exposure function, any exposure time
settings made by the user prior to image capture
will be changed.)
After selecting Auto Exposure, select from one of
the following image acquisition settings:
1. Best (Longer Exposure) exposes the image to
the maximum value of the histogram (65,000
gray levels).
2. Better exposes to fill the histogram 50% so the
brightest portion of the image is at 32,000 gray
levels.
3. Good exposes to fill the histogram to 25% or
16,000 gray levels.
4. Minimum (Fast Exposure) exposes to fill the
histogram to 10% over background. Minimum
and Good settings are particularly useful for
chemiluminescent imaging applications and
