Hello dear colleagues,

ImageJ seems to be displaying some files incorrectly here.  Please check
this link: http://imagebin.ca/view/6z_mf8hh.htmler 

There I have the imageJ and another application (nautilus) displaying
the same TIF file. The imageJ display seems more grainy and darker.
 
The interesting thing is that it does not happen to every file! Specimen
photos are displayed as expected.
It only happens to the photos which I took without a specimen, that is,
only an empty glass slide was placed on the microscope, so I can
subtract light path aberrations from the specimen photos.

I can't subtract these photos the way it is being displayed. (I
understand I have to convert photos to 8bit grayscale in order to
accomplish this, but this issue would have to be solved first.)

I am using imageJ 1.42h in ubuntu 64bits.

Any clues?

Thanks
