Mac OS X
The color management framework of OS X (ColorSync) automati-
cally detects the presence of calibration curves in an ICC-profile and
downloads them into the video card at system start-up or when allocat-
ing a different ICC-profile using the monitors control panel.
Windows
The Windows color management framework (ICM) does not support this
functionality, a separate LUT-loader is required. SpectraView Profiler
contains such a LUT-loader which is installed automatically into the
start-up programs folder when installing
SpectraView Profiler .
At Windows start-up the LUT-loader downloads the calibration curves
into the video card. When changing the monitor profile, the LUT-loader
must be launched manually in order to download the correct LUT.
The downside of a software calibration, compared to hard- ware calibra-
tion is the reduction of tonal values by using 8 bit LUTs in the video
card. Depending from the extent of the correction, banding and reduced
definition in highlights and shadows can be then consequence. This
effect is annoying in technical vignettes, but it’s not so visible in photos.
Make sure that the „SpectraView Profiler4
VideoLUT Loader“ is the only LUT-loader
in the Windows start-up programs folder.
There will be a LUT conflict, result- ing in
a wrong calibration, if other LUT-loaders
such as Adobe Gamma are launched at
system start-up.
