I tried that. I also tried extended depth of field in Adobe Photoshop
CS4. I must say InageJ failed. I have photos of zebrafish and got to
stitch a few of them together because of the thickness of the embryo,
not all planes are in focus. I tried different versions and settings of
Extended depth of field in ImageJ and got terrible results. Then I did
CS4 and presto. 4 clicks and I was there. I guess the main thing is that
CS4 aligns the sections. When you change focus to get different parts of
fish sharp the entire specimen shifts a bit (normal). ImageJ is however
unable to adjust for that. CS4 first aligns then does the rest. The
results are great. Any idea how to achieve that in ImajgeJ
