pls, on ImagJ

Dears users:
  I´m intersting in the soft ImageJ, but I don´t know it by the moment. I need to substract two TIFF images (16bits) and to have the result as a new TIFF image.
   
  Please, it´s possible to do this with ImagJ?
   
  Thank you!!

Hello,

I apologize for my ignorance about 16-bit TIFs ahead of time if the
following advice is not helpful.

If you are having trouble opening your TIF files into ImageJ, then there may
be a plugin here that expands your ability to open different file types:

As for subtracting...

First Method:
Open both images into ImageJ. Then Process -> Image Calculator...

Set Image1 and Image2, and Operation: Subtract. You can specify a 32-bit
Result, which may help with what you need.

Second Method:
Open both images into ImageJ. Then for one, Select All -> Copy.  Edit ->
Paste Control... -> change to Difference.
Click your other image, and paste.

While these two methods are supposed to be identical (or so I thought) the
first method gives a better result for me, the second has artifacts.
