You need to add to your highres layer
PROCESSING "SCALE=AUTO"
Or per band scaling. I done thing most browsers know what to do with 16
bits per channel.

Hi there,
iam having some trouble to serve 48 bit geotiff images with a mapserver
7 wms. I created to layers for speed purposes with scale limiters. The
lowres layer is served well and looks good, it is 24bit geotiff
data(8bit per channel). But if the layer changes to the highres, 48bit
geotiff data(16bit per channel), the data is shown wrong.
I searched for some hints regarding a similar issue but could not find
something.
This is a screenshot of the loaded highres layer. It does not matter if
i load a bbox inside the browser, qgis or another wms client. The
highres data looks always the same.
