Hi Wayne,
Thanks for the information. I've hit a small snag. The camera I had planned
on using does not function via VDig and Quicktime. I wonder it there is
anyone who has worked with older webcams who might have a workaround to
this. My camera is a 3Com USB that has excellent low-light capabilities and
can capture emission spectra at very low light levels. It works great with
JTwain, but not Quicktime.

You can create ROIs, generate histograms (press "h") or generate
profile plots (press "k") while the QuickTime Capture plugin
(
http://rsb.info.nih.gov/ij/plugins/qt-capture.html) is in "Live" mode.
This plugin is built in as the File>Import>Video command on the Mac
version of ImageJ.
