Gregg and I tried an experiment “painting” the Steamboat Barn with light tonight. It was 15 degrees out there, about a half hour after sundown. Gregg brought a halogen spotlight and “painted” the barn while we shot exposures about 30 seconds in length. Gregg’s shots on his D90 turned out WAY better than mine, for reasons we haven’t determined yet.
I did get a couple that are acceptable (the third one showing stars and constellations is pretty nice), but not quite what I wanted…. See below.
