film, digital sensor, Shroud of Turin, whatever
I was thinking about HDR (high dynamic range) photography the other day. . . . Let’s start with what dynamic range is. I’m gonna butcher it up a bit here. To be honest, I skimmed a PhD thesis worth of stuff on dynamic range in the last hour or so while contemplating this article. It’s deep and I’m gonna gloss across the top. Dynamic range is essentially how many zones, or f-stops of data your medium (film, digital sensor, Shroud of Turin, whatever) can capture without losing information. In other words, how much contrast can you capture?
Wonder why? We are seeing many more “off the wall” references to the shroud than we used to. Anyway, the posting has nothing to do with the shroud. But if you are interested in photography, this posting and the whole blog is very interesting.
