Taken midday with the Singh-Ray 830nm I-Ray (pure infrared) filter, a neat but finicky filter that can only come out to play with this camera/lens combo in the brightest conditions, as it's equivalent to a 20-stop ND filter in the visible spectrum. Hence, what was metered here at 1/2500s became a 7 minute exposure.
For anyone interested in long exposures, I find the NDTimer app indispensable (available for iOS; not sure about Android). I don't know why a modern DSLR can't be programmed for an arbitrary shutter speed---this would be most convenient for long exposures. Why the 30s limit? Is this a holdover from analog?
