Re: What's light integration ??? /UV exposure light boxes

A light integrator measures light output and accurately controls total
exposure. A simple exposure unit with fluorescent BL tubes will work just
fine. I have a homemade light box (without integrator) that works well for
producing cyanotype and gum prints.

> Ok, I'm stupid but what the heck is light intergration and these units
you're talking about. Here I was just trying to decided between 24" bulbs
or a metal halide (although this in itself is confusing me to no ends). All
I want is a simple set up to put my contact frame under for 12 x 18 max
size. Why won't just getting three or four two bulb holders with the BL
bulbs in them, set 'em above the neg, plug 'em in and expose work?
