Appendix H. Fluor-S MAX

H-9

For most applications, you can select an exposure time, capture an image, study it,
then adjust the exposure time accordingly. Repeat this procedure as many times as
necessary to obtain a good image.

For chemiluminescent samples, which degrade over time and emit low levels of light,
you can select a high exposure time initially and use Live Acquire mode to save
intermediate exposures (see following section).

Preview

For shorter exposures, you can use Preview to test different exposure times. Click on
the Preview button create a preview exposure and display it in the acquisition
window.
