Some call it painting with light, others call it making luminograms, and still others don’t bother with a proper name for it, they just go into the darkroom and fool around until somehow, against all odds, they manage to do it. It’s not easy. We’ve tried before to describe how Mike Jackson proceeds, first in 2015 and again in 2016, but according mail from readers we’ve come up short. It’s just too difficult to describe unless you have a darkroom, good lightbulbs, proper chemistry, tons of photo paper that you can run tests on and waste, lots of time, and a vigorous imagination – which in this digital era limits prospective students to quite a small number. For a start, if you want to try it yourself, I would think of employing scrims, gobos, fans, and hand-waving, but this is not an authorized recommendation: the thoughtful man who is redefining luminograms for the modern age has remained mum. This leaves him pretty much the whole terrain, so let’s see how he’s progressing.
