Hi,

I currently working with TEM image data. I imported a series of dm3
images via the Import -> Image Sequence command.

If I open a single image of that image series with Open -> Image it
seems to have another contrast:

But the pixel values are the same in left (sequence) and the right
(single) image, so there is not a problem. However, the images are 16bit
images and I have to convert them to 8 bit. I do that with  "Image ->
Type -> 8bit". But now the pixel values are DIFFERENT:
https://dl.dropboxusercontent.com/u/560426/contrast_bug_8bit.png

The marked pixel has in the left image a value of 22 and in the right
image a value 8. It think this must be a bug because this is not the
expected behaviour, isn't it?

Cheers,
Thorsten
