Digital BW, The Print

I use an Ott light to partially simulate daylight, but mine's clearly
a very partial, chopped spectrum. Shoot some color swatches with
Ektachrome to see what I mean. Mine's significantly inferior to the
common "daylight" fluorescent tubes that I use in lightboxes.

Ott plus tungsten seems to me to be a good mix for print
evaluation...it's not daylight, but most display situations aren't
either. I find this mix works well for matching matte prints to my
monitor.
