Re: Light source for evaluating prints?

2007-01-30 by michael3442

After raising this issue with my first post, I've been doing a little 
research. It appears there is a preferred color temperature for 
viewing color artwork and a fairly specific color temperature which 
is perceived to be neutral - neither warm nor cool. The two temps are 
3600K in the first case and 3750K in the second. This was found in 
two studies at the Applied Vision Institute, Dept. of Psychology, 
Brooklyn College, CUNY. Here's the link to the .pdf of the 2nd study 
which references the first: 
http://www.solux.net/ies_files/MuseumLightingStudy.pdf 

Also, at Solux's main page and down toward the middle there's the 
following sentence with a hot link: "Some of the hottest areas for 
SoLux use are: light therapy, and for photography/digital color 
proofing." (Unfortunately, their pages do not show unique URLs.)Way 
down on that linked page is this about Caponigro: "John says he uses 
the 3500K bulbs for his studio and gallery. He evaluates and displays 
prints under the same light. He also uses four SoLux Gooseneck 
fixtures for portable light sources: two with 3500K bulbs to evaluate 
display conditions and two with 5000K bulbs to evaluate color 
management issues, monitor calibration and soft proofing."

In the final analysis, I think I'll print for the neutral lighting 
conditions found in most galleries, around 3500K (general halogen 
temp.). I have found four Sylvania Minitwist fluorescent bulbs at 
Menards which have temps of 2700K, 3000K, 3500K, and 5000K (marked on 
their base-unlike most other brands). So far I like the two middle 
temps, although seeing a difference is a little hard. The very warm 
one and the daylight bulb seem too extreme (although most of my 
home's bulbs are tungston and warm.)
