I took this shot tonight to test out the Sigma 10-20mm. Pleased with the result although it could be a bit sharper in places. Better skies would make this shot more interesting, too.
I try not to push my HDR photos too hard. Sometimes, though, it's worth it to get the look I have in my mind. The shot above was taken from inside a limestone mill. There was limestone dust everywhere. It was also dusk during a cloudy day, so the mood was a bit menacing. Anyway, this image comes close to the gritty, raw image I had in my mind when I took the shot.
