I totally understand the 180 rule....
What I'm asking is if there's any way to tell ML to START at at higher ISO, then ramp DOWN.
Currently, if I'm trying to bulb-ramp a sunrise, I set my initial exposure—say 1 second at f5.6 @ 1600 ISO, then I take the reference picture. When I start the intervalometer with bulb-ramping set to sunrise... ML changes my exposure back to 100 ISO, and then starts ramping...
