Hi Everyone,
One of the most fascinating features of ML (for me at least) is bulb ramping. However I am trying to master this and don't seem to get very far. Up until now I am getting very drastic steps in exposure changes witch this far I have not succeeded to iron out in the free version of LRT timelapse... Am I doing something wrong? since the sun only sets once per day I can't run too many tests and was hoping for some of your valuable advice!
Thanks in advance!

You are probably using a very low ramping speed (that's when you get huge ramping steps).
If you use LRT, the nightly builds include a ramping mode designed for that program, but it's still bleeding edge.

This sounds very interesting! I wander if its worth the risk to upload on my 5DII or newly purchased 600D... have you tried it on any of your bodies? Thanks for posting!

Bulb ramping is history, use ETTR + post deflicker instead: http://www.magiclantern.fm/forum/index.php?topic=5705.msg41478#msg41478
