[filmscanners] RE: Monitor calibration



Understood, thanks,
Basically, I adjusted contrast and brightness of the monitor according to
the instructions of Adobe Gamma utility (full contrast, brightness was
settled at about 45-50 %).
BTW, trying to set this gamma explicitly in Photoshop produced an error
stating that Photoshop will not accept gamma value greater then 3. That
really confused me, since as for my understanding if the developers of
Photoshop limited it my this value, the real world gamma indeed should be
lower.

Regards,
Alex Z

>However, they insisted on using quite exaggerated gamma (3.06) with the
coordinate values they provided and this gamma indeed seemed to be extremely
high for my liking, so I went back to regular one (measured visually in
LittleCMS as about 2.4).

A gamma of 1.8 for Macs and 2.2 for PCs is usually regarded as normal.  The
eggaggerated gammar that they suggest my be based on your monitor's
brightness and contrast level controls (actually on the monitor itself
physically or electronically controlled via on-screen controls)being set at
a particular level.  If you turn the brigtness down and the contrast up, a
different gamma from that called for by the manufacturer (3.06) might be the
appropriate one for that set of settings.
