Digital BW, The Print

As well it should. Just as it makes a huge difference if one varnishes
or glossy coats a matt print.  I believe , I think rightly, that
trying to compare matt vs glossy prints d'max via the common 45 degree
instruments is futile. It's like comparing apples and oranges.
These instruments take apparent density measurements, not actual
absorbed light measurements. That's not much of a problem with matt
surfaces, except for those with extreme textures, but takes on a whole
different character when, as with glossy surfaces, much of the
impinging light is being bounced off of the surface before it ever
gets near any ink to be absorbed.

Try reading a high d'max glossy print with both a 45degree instrument
and an integrating sphere instrument in specular included mode where
it attempts to read All of the reflected light from every angle, and
one will quickly see the vaunted high d'max number drop into the
proximate range of the apparent instrument. 

Everyone knows if one tries to look at a glazed print from the wrong
angle to it's lighting that not only will it appear washed out, it
might even disappear totally from sight. So it is with glossy prints,
as Paul has hinted.

Regards,
Duane
