f/11 at 20 seconds. How did you meter this to keep from burning the windows out? If you bracketed the exposure, how many frames did you shoot?
Your technical command of exposure continues to amaze me. Framing is not bad either...
Thanks for the comments about my church shot. Technical command of exposure is quite a compliment, but, in truth, I just keep things very simple. In the days of film there were only two variables, aperture and shutter speed. Now, with digital, we have a third - ISO - since we can change ISO values on a shot-by-shot basis. But I use a tripod all the time, so two of these variables tend to stay the same: ISO 100 and f/11. That only leaves one variable, shutter speed.
I use manual exposure, make a guess at an appropriate shutter speed, take a shot, check the back of the camera to see how it looks. I make further adjustments to get a correct(ish) exposure. Then I generally take another couple of shots, either side of this value to give a choice of three pix once Ive downloaded them to the Mac.
Its trial and error, really. Im sure there are quicker ways to get to a similar result, but my photography is about slowing down, not speeding up. What matters, for me, is finding a composition in which the subject of the pic and the lighting conditions are working together not pulling apart at which point the exposure values pretty much look after themselves
A shot from the same church (Torpenhow, dating back to 1120 ). HDR from 7 exposures (it was very dark in there), to get some detail into the Norman arch, while keeping the gloomy mood...
