Images opening all Gray

[J. Daniel Fenn]

Everytime I open any of my images, they always come up completely gray.
Then I have to open the Brightness Contrast setting to reset the
histogram/look-up tables/levels of the image.

I'm using Fiji, and I ran the updater this morning, but it is still
doing it. It ends up requiring a fair amount of time to adjust that over
hundreds of images I open. Can anyone point me to a potential fix?

Hi Dan,

can you potentially attach an example image, so we can try and see, what
might be the problem.

Jan

Dan,


Can you say a little more about these images?  Are they RGB, 8 bit, 16 bit,
etc. MIght they have been saved with a particular LUT?

When you first bring them up, can you look at an image histogram to see
what the pixel range is?

If you open your images via the File > Import > Bio-Formats command, you
can check the "Autoscale" box in the "Color options" of the Bio-Formats
Import Options dialog box, and your images should always open autoscaled.
