Color-balanced green-blue cast. Increased contrast
with levels but lost face detail and used history brush
at 21% to bring back the facial details. Darkened to
what it looked like when I was there, used hue-saturation
to bring back only reds.
This is a gorgeous window that is a copy of the original,
which was recently restored but placed in a museum instead
of its original religious setting, to preserve colors, etc.
More of the church and window at the Siena1 gallery.
