I promise I'll stop writing about the Sigma DP1 Quattro I was loaned last month, but not just yet. I took this picture soon after the camera arrived, in a wood not far from where I live. I've photographed this tree a lot--in fact it features in one of my pieces for the Northern Exposure exhibition--so I know this is a difficult location in terms of available light. In the past Sigma DP series cameras have struggled with low light, high contrast situations, so this was a deliberate test. The Quattro did very well. That wide lens makes for a lot of drama.
Technical stuff: This is taken handheld at ISO400 and 1/60th of a second, settings which, though I love it dearly, I wouldn't even consider with my older Sigma DP2 Merrill. I underexposed this to keep the shutter speed up, so the post processing involved fixing that and dropping the saturation a bit.
