  1. Edit Photo (Part DUEX)

•    Use Eraser to delete Nucleus and other erroneous background.  Overall just get of bigger parts b/c little parts will go when photo is analyzed under image J. A good indicator of particles that should be deleted is to set eraser at 10 pixels and delete everything smaller then that, but once you get the hang of that just use the big eraser.

  1. Save Photo

- This looks complicated but once you get the hang of it, it is much more accurate and easier than Image J for editing the photos.
