I can't agree with thisI did not test for what happens if you take a short exposure and try to use that dark frame for a long exposure. I don't see why someone would do that. Presumably a photographer knows when she/he is going to do long exposures, so in preparation, with the knowledge that the first dark frame in Aerial mode will be used for all subsequent shots, the photographer would take a "typical" long exposure frame as the first frame so a roughly relevant dark frame would be used. This is one of the things I learned (thanks Doug!). If I ever go out shooting long exposures, and don't want to wait for a dark frame, then my first image in Aerial mode will be a long exposure. I could do that while driving to the site!

Having the flexibility to choose different exposure times ranging between 2~16 minutes is an essential function for a CMOS back. Cloud can move at different speeds, and light condition changes over time during sunrise/sunset, not to mention the battery and heat restrictions. If the IQ3 100MP doesn't support this while the IQ250 and the other smaller sensors can then it's gonna be a huge draw back for me. I have never shot preliminary darkframes with the IQ250/D810A/D800E before.
If you have time please test the underexposed lightframes and help me fill in the table! But I'll test that with another demo unit in about a week anyway.Now that's just darn funny.
