lighting up history

Glass plate- click for reversal

Toronto. Around a century ago and earlier, cameras used glass plates to hold the sensitive media. Since the luminance values were reversed, the image on the plate was a negative. To view the image you needed an educated eye, and a light box to evenly illuminate the negative.

Today we have oodles of discarded monitors using thin fluorescent tube for even lighting across the entire screen. Member Harold Staats came across this Youtube video showing how one person created a modern light box from a discarded c2002 Windows monitor.

Watch it and see how you can turn a piece of old computer gear into a useful light box so you can see and photograph the old glass plate negatives you unearthed at one of our fairs or auctions!
