            Bug ID: 1206
           Summary: Wrong merging from stack to RGB
           Product: Fiji
           Version: unspecified
          Hardware: PC
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P4
         Component: Plugins
          Assignee: imagej-bugs at imagej.net

I have a big image (3.7 GB) that is the results of the stitching of several
hundreds of microscope pictures. At the end of the stiching procedure I got
three files contaning the three different color layer of the composite picture.
Each of these is a TIFF 16-bit image. 
If I open the three layers as a sequence (I have uploaded a screenshot of this
picture: three-layers.png) I can try to convert it in a single layer RGB image,
via Image->Color->Stack to RGB. I get a color picture, but that is mess up (see
rgb-merge.png). 
If I export this image as a png, for example, and I open it with Gimp, it looks
normal. So there is a problem somewhere with the visualiziation of this image. 

Thanks for helping.

Antonio
