I have tested this and found it true... assume it's the actinic quality of
the light... probably more broad-spectrum outdoors, hits on more
cylinders, so to speak.
In addition, it's possible the light outdoors was more contrasty, which
would give the up part a bit of a zetz -- don't remember whether Gary
mentioned that or not...
