[Qgis-user] Displaying 16 bit per channel images

[Gabriel Lema]

Hello,

I was wondering what QGIS does to display 16 bit per channel RGB
images. I would like to covert them to 8 bit per channel normal PNG or
JPG image, but when I save it using the "Save as..." in the "Project"
menu, I get a low resolution image.
If I could have access to the conversion from 16 bit to 8 bit that
QGIS does, which makes a good looking RGB image, I could do that same
conversion on any other software, and save it full resolution. Is it a
gamma correction? I've tried many different, but haven't been
successful so far.
If I save it using gdal_translate I get a greenish looking image, that
is very different from the good looking image that QGIS displays.

Thank you for your help.
