Hi,

DSS does this as well. When you save as TIFF format you are basically compressing all the brightness levels into 0 to 64k of possible brightness levels.

You need to take the registax image and adjust it in photoshop using curves followed by levels adjustment for a number of iterations to streeeettttcch out the brightness levels in the image.

If you look in the articles on this site there is a good tutorial by Eric (Ezystyles) that explains just how to do this.
