Colin, some good ideas! Linear or logarithmic bulp ramp?

Post or PM me your email and I will send a link (tomorrow) so you can have a play with my raw images from 2 eclipses (2008, 2010), and see which exposures give the best results. Keep in mind they were taken with a 400D. I will do the same.

From memory I could not squeeze out enough landscape light from 1/4s, but dynamic range on the 5DII is obviously better.

BTW, will serial port bulb control through EO be accurate enough for bulb ramp?
