Hey guys!

Dont want to feel like im bringing up old news.... but I was wondering if someone can help me... I'm on a 5D Miii. Latest nightly build.

I'm Using Dual ISO with Raw video. This is what happens when I dump in DNG files I get using MLRawViewer 1.3.3 to preview and extract the files. Is there a better way of doing it?



It's showing errors, but it's doing the job.....however the ISO values it is using are incorrect from the looks of those lines (800/200).

The ISO I use was 800 and the recovery ISO I used was 3200.

Side effects noticed by me: there seem to be more hot pixels than usual during long exposures, and the ISO alternation confuses the feedback loop a bit.

About temperature: anybody can run an experiment and record it during a timelapse, for example, with and without dual iso; if there are differences, such a test should reveal them. I didn't run any temperature comparison, so I can't tell.

I took around 20000 pictures with dual iso on 5D3 by now (including some timelapse that I have yet to postprocess), so I guess it should be fine. Of course, that's not a guarantee.


This is good enough confirmation for me about it being safe to use. :)

May I ask, where you heard it and who told the tale? Link, please!

Ciao

Mostly been hearsay by people who havent used ML before and also mentioned in the original post!

this is just my first time trying the nightly builds!!! didnt want to have a bad experience lol....

No bad sensor exposure, same shutter count as a regular timelapse.  So this improves on HDR timelapses in the shutter count area, because instead of 2+ (usually 3 or more) per frame for an HDR, you get increased DR with one shot.  Just a heads up, as with HDR timelapse, your post processing time increases dramatically.

I know the drawbacks/benefits of doing HDR in post lol.... What I mean is, will shooting in dual ISO mode put more strain on my cameras sensor at all? I've just hear that Dual ISO mode can put a lot of stress into the sensor causing problems with it. Or should I not even worry about it?

Would it be safe to use Dual ISO mode for a timelapses? taking maybe 300-500 shots at a time? Will this affect my sensors at all?
