long exposures for S9100
The S9100 (for some reason) limits bulb exposures to 30 seconds with a cable release. I considered using the multiple exposure mode with an electronic interval timer set to fire every 31 seconds, but I don't see any way around the extra LCD interaction required to take the next exposure.
Any clever work-arounds out there for making a 20 minute exposure without human intervention? At this point I've resigned myself to multiple 30 sec exposures merged in PS.
