I just installed a nightly build of ML and can't find what is described in the user guide as follows:
Settings for auto ramping:
Mode: sunset / sunrise / auto. In sunset mode, the exposure will always increase. In sunrise mode, the exposure will always decrease. This idea was suggested by Tom Lowe on RedUser.net forum.
I used this function when v2.3 came out a while ago. Is it still there? Are the alternatives just as easy and useful for filming sunrise/sunset transitions?
It was removed and replaced with AutoETTR + Deflicker (http://www.magiclantern.fm/forum/index.php?topic=5705.0)
You can do the deflicker in camera (it's a separate module (http://www.magiclantern.fm/forum/index.php?topic=10496.0) now) or in post (http://www.magiclantern.fm/forum/index.php?topic=8850.0)
You can save a lot of time by just doing sunrise and sunset, and then blend together in post.
Depending on subject, of course.
You could also save a lot of time by not shooting a timelapse...
There's just no way to capture full day into full night without some kind of exposure change.
I felt it was really easy and worked well with the old way:
I will try Auto ETTR and see how it compares.
