I was leaving my house a few nights ago and noticed how the white edges of these leaves seemed to be faintly glowing in the low light. I set the DP1 to ISO 800 with the aperture wide open at f/4.0 The indicated shutter speed was about 4 seconds, impossible to handhold and leading to a daylight looking shot even if I did put the camera on a tripod. So I cranked down the shutter speed until I could hand hold at about 1/2 a second. So maximal ISO, but 3 stops underexposed.
Converted to black and white, I was able to render what inspired me that night.
