What´s "AETTR"??
Do you mean something with AutoExposure? Don´t use this for shooting panos with bracketing. NEVER.

The point with bracketing is to have different exposures. So take a measuring manually and set
the time for the correct exposure, resp. an optimal exposure. The camera takes under- and overexposed pictures then.
That´s what you need.

I really don´t know what "AETTR" is.

Klause,

see the link in the magic lantern manual:
http://wiki.magiclantern.fm/userguide#e ... right_ettr
http://wiki.magiclantern.fm/ettr

it allows automatic exposure setting to limit over exposed pixels. i tought i would experiment to see if it adjusts the "0" EV shot and brackets around that or if it would set the exposure on all of the brackets. If the later is the case (and i suspect that it might be) then, as you say, that pretty much defeats the purpose. but i thought i would give it a try and see what happens.

Seems so . . ;)

The trick is to set the optimal value for "0". Look for an average point of brightness and set this one as "0".

The rest happens from alone.

but if the optimal value is changing then ...

i've been thinking about bracketed panoramic shots at sunrise or sunsets where the exposure requirements will likely change during the shoot since with the longer exposures included in the brackets might be 25 or 30 seconds or so. i like shooting sunrise or sunsets but i haven't tried a panoramic, so i'm thinking about how i can change the baseline during the process.

looks like ML bracket will work in aperture priority maybe i'll just try that for starters.

i told you ... i'm over complicating again.
