Ideally I would view my prints using a GTI light box or use Solux lights. What about the argument that most people are going to view their prints if their lucky using halogen lights. I've even seen art galleries that just use halogen track lighting that is not exactly perfect. Right now I use my Lowes track lighting and then use window light, but after reading through Mr. Schewe's the Digital Print I'd like to try and be more consistent. What about using a Solux 4700 Kelvin bulb on a floor stand. I'm thinking this would be fine to view 13x19 inch prints as they come out of the printer.
Unless the illuminant has a really odd (poorly behaved) spectrum, your eyes should adapt to the new conditions. OBA's in papers can exhibit issues based on some illuminants that could be considered '
daylight' (Fluorescent). The Solux spectrum is about the best plot of man made lighting I've measured or seen so expect for heat and issues controlling it, hard to beat. But again, most of us want a print viewing booth next to the display and produce WYSIWYG, after which if you move the print elsewhere, one hopes that it is of sufficient intensity and quality that you adapt to the conditions and it doesn't look '
wrong'.
