Hi,

I have the following problem:

I open a raw image (16-bit unsigned) do some treatment (no change to pixel
values though) on it and than I save it again as raw. If I again
open the image as raw, the pixel values are rescaled, different from the
original. Some of them even flow over the 16-bit value limit. Even worse, the
scaling is different if I adjust brightness/contrast. I have un-checked
option to Scale image, when converting, but the result is the same.
Preservation of the pixel values is critical for what I do.

I run ImageJ 1.36b on MacBook Pro. Thanks for advice in advance.

Martin
