I was in Peterborough Cathedral yesterday, seeking sanctuary from the January sales. It’s the first time I’ve ever been and it is a fabulous building. If I can wring a little more from the pun, I have a confesssion to make. What I did know pre-visit: that it was one of the early inspirations for Ken Follett before writing Pillars of the earth, one of my reading highlights from last year. What I didn’t know: that it is the resting place of Katherine of Aragon, and formerly that of Mary Queen of Scots. Doh!<\/p>\n

I’ve tried to take pictures of stained glass before with universally poor results – though to be fair, in unplanned visits sans tripod. I went armed yesterday, and after trying a variety of exposures, decided on a whim that it would be worth trying some bracketing. Despite the fact that the composition is awful [the picture below is a portrait crop, with enough surrounding detail to show that the stone is exposed, but the tops of the windows annoyingly absent], I’m impressed with the balance of light that the HDR managed to produce.<\/p>\n

The three exposures are: F14 for 0.3 seconds, F6.3 for 0.6 seconds and F9 for 0.6 seconds. This is at 22mm on my ultra-wide, and ISO 100:<\/p>\n

In Photmatix, I’ve set: Strength:70, Colour Saturation: 46 [i.e., defaults], Luminosity of -3.1, micro-contrast: 2.0, and finally, micro-smoothing 0.<\/p>\n

There is a slight green cast to the stone, but this is a reflection of reality [the amount of green glass], and is present in the central exposure I bracketed around. I’ve intentionally left it in, for what it’s worth.<\/p>\n

I’m going to have to go back now: as so often happens for me, what I consider to be the result of the day was – not quite a fluke, more of an afterthought.<\/p>\n","protected":false},"excerpt":{"rendered":"
