I thought so too. Lucky shot

Thanks!
Used a 5d mark 3

Sorry bout that. Will post smaller sizes from now on.
//Thanks

Tried a little quick and dirty test filming in 3x crop mode with a 14mm samyang lens. I used 6400-100 setting in a very dark kitchen. Surprisingly I can,t find any moiré or aliasing. The picture is totally clean! Check out the movielink. Genious work.

Also a link to my still pictures made with dual iso on youtube.

unfortunately not. 5d mark 3 and 7d for now I believe

ETTR is a great function that require some testing out. It,s in the menu. You can search on the forum on how to work with it.
I just hit ETTR on and then proceed to dual iso where I set the interval lets say 100-1600 or 100-3200. WHen I hit the set button the mirror flips and the ETTR is making its magic (calculating exposure to the right). Don,t be surprised if the iso and shutter changes. I believe the intervals stays the same though. Not sure. Than take the picture.
You could always do it manually by selecting the first iso for the highlights and then the other iso for shadows. If there,s a lot of contrast usually between 100-1600 or bigger works nice. Even 100-6400 could work sometimes.
Yup, it,s kind of magical. Feels like another camera atm

A thread to share photos taken with dual iso. If you want to try and learn how please enter this thread here. http://www.magiclantern.fm/forum/index.php?topic=7139.msg62864;topicseen#msg62864

Some more examples of what dual iso can achieve. The shadows pop out like never before. Mostly used interval between 100-1600 and ETTR to find exposure settings. Works perfect most of the time. From a visit in Copenhagen. I used a 5d mark 3.

*updated with more pics and with 900px width, maximum forumsize.

Due to bandwith reasons and uploaded images being too big i decided to post a youtubelink containing the stills instead. Enjoy.

Yup, used cr2hdr. In the nightpictures there is some green and red moiré or something. Only minor though. In the daylight pictures almost none. When filming a lot more green/red issues appear. Mostly 100-1600 or 100-3200 used in the pics. Clean the pictures in lightroom to get rid of purple fringing

Try a transcend 64gb 1000x, perfect compromise of price with fast working speeds. That,s my conclusion when choosing between komputerbay and lexar

Could that beepsynch work for premiere or after effects aswell?

Hi Alex. They,re fullres pics. Good stuff

Some random examples of dual iso cr2 images processed in lightroom. Nothing to compare to but the original exposure.

Hey Squig, gotta install virtual box. Slow conversion but works on a mac and win 7

Awesome! Will try it out tonight. Good work

@ap1hk. See you got something going on mac. Why not share it?  A lot of guys out there in desperate need of a mac conversion tool

It,s already in the post processing description as how to join split files but it,s always goid with a little repetition

Not working for mac yet

You process the rawfile like regular rawfiles. Check out the thread that,s called massive dynamic range dual iso. Use the latest raw2dng.exe converter

Of course one can spend a whole week comparing. Actually tried 3200 1600 and 12800.  100-6400 worked best. Fully aware of the algorithms with the converter creating the hdr and its importance. My tests so far are a blend of pseudoscience combined with vacation and just having fun
By the way Ilias, did you look at the noisetest dng,s?

check out my picture of a 100-6400 some posts up. Worked rather well.

@Ilias

updated my link now containing the first dngfile from both of the examples. base-iso 1600 for both files. 6400-1600 on the dual-iso. (reversed due to converting issue, still base-iso 1600 though). Lighting and camerasettings identical for both shots.

Wrote wrong. Dual iso was shot 6400-1600, regular shot 1600, same lighting, same settings on the camera same processing in lightroom. Could upload the first dual iso dng later today. The other dng is the first one I believe? I used a lightbulb

How can you whitebalance rawmovies. Rawmovie converted with latest raw2dng.exe. Dngs provided in the link. The test was aimed for noisecomparison. Thanks for watching

When I made this comparison with 100-6400 and regular 100 iso one realize there has to be more shadows regained than 2 extra stops. By dividing in such a big interval i,d argue that you suddenly gained about 4-5 extra steps. I was able to lift the shadows to the extent I couldn,t go any further with the lightroom exposure slider. Could have used the brushes though but still.
These shots are even converted with the old converter.
