Hi,
I add some information, after the last questions:
*- to Marco Ugolini:*
*- What monitor are you using? (Brand and model)*
The Mac' monitor.
*- Is the purple hue visible when looking at the monitor dead-center (at a
90-degree angle with the center of the display's surface) or only from some
other angle?*
Watching the monitor at a 90-degree angle, in front of..
*- Have you tried attaching another monitor, then calibrating and profiling
that one to see if the problem persists?*
I have a Eizo S2000, now it's not available, is in another house. Maybe, by
the weekend, I recovery and testing that.
*- Is there any visible anomaly in other ranges of color besides blues?*
In other colors I don't think there are obvious problems.
*- Is the monitor uniform across its surface, or instead does it exhibit hue
shifts in certain areas when a uniform gray is sent to it in Photoshop in
full-screen mode with no visible menus or tool panels?
*Monitor is uniform.
*to Cdtobie:*
I tried what you suggest, but also with ProPhotoRGB workingspace, the
problem persists. thanks anyway!
Thanks to all for your cooperation.
