Hi Karsten,

have a look at the Browseable Sourcecode under Developer Resources,
http://rsb.info.nih.gov/ij/developer/source/index.html
In TypeConverter
http://rsb.info.nih.gov/ij/developer/source/ij/process/ 
TypeConverter.java.html
you will find convertShortToByte().

Without scaling (Edit/Options/Conversions Scale when converting):

   16-bit values between 0 and 255 are unchanged, larger values  
become 255.

With scaling:

   Gray values as on the screen (i.e., those set by Image/Adjust/
Brightness&Contrast) are used.
