(Its okay if little fuzzies are on side because will go away during threshold and following steps.
  •  Click adjustment layer button > Click Threshold.  Find best fit.
  • Click Shift, Hotkey & E at same time

•    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
  • Make sure photo is put in separate folder designated for pictures ready to be measured in Image J. Do not go to IMage J until you have a lot of pictures because Image J will run macro that can analyze many areas very quickly.

- 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.

To measure area of pictures go to child "Image J Macro Area analysis"
