I did my first bulb ramping test with the new features of 2.3 last evening. Canon 60D, fw 1.1.1, MF Nikon 28mm f/2, interval of 10 secs.
Settings were:
Auto ExpoRamp: Sunset
MAX Rampspeed: 0.001 EV/shot
Started off with a ND filter witch I removed at :13, you can see the color shift. I had to toss 3 images, but ML recovered very well.
Here is the video:
Here is a cropped video of the sky:
Lastly, here is the log file:

Still quite a bit of flicker, something strange happens at image 4628. The exposure gets longer/shorter/longer. etc. That should not happen with sunset setting, correct?
I made some mistakes here: removed the ND filter much to soon, causing the camera to use fast shutter speeds, resulting in flicker. Not sure if I set ML up to fail as I don't fully understand the MAX Ramp speed setting, and I'm not sure if I used the correct percentile for metering. Looking at the log file, I think I used 67th...?
I intend to try again this evening, weather permitting. Any tips appreciated, any questions gladly answered.

Thanks, A1ex, I'll post to this thread as I work my way through this process.
