 Manual Exposure — use this setting to manually override automated
imaging. Exposure time can range from 0.001 to 7,200 seconds with the
ChemiDoc MP imager.
 After imaging a gel with automatic exposure optimization, the display
provides a reference point from which to set your manual exposure time.
Note: You can view the exposure time of the image in the Image Info
window (see Image Info on page 115).
Step 1. Gel Imaging for Multichannel Protocols
You must configure acquisition settings for at least two channels to create a valid
multichannel protocol. Each channel can be assigned a color (red, green, or blue) so
you can easily identify each channel. Configure each channel separately.
