These photos of St. Peter’s Collegiate Church, Wolverhampton were taken on a winter’s night using an automatic setting. When I was editing them in Photo Gallery, I simply increased the exposure on the histogram, and this is what emerged. I like the way the solid stone building not only lacks colour but also substance. So thanks to Jennifer for the interesting challenge of eigengrau: “intrinsic grey” or the colour seen by the eye in perfect darkness. This is my stab at conjuring it.
