I was able to download the full-res dng file, and open it with GIMP 2.8, and didn't find much artifacts, and, when shrinked to 1920x1280, the picture was beautiful, but I couldn't get that much DR as the whitepaper did.

Couldn't wait to see when this good thing, plus raw video, plus 10 bit downbit raw video, will come to 7D. And I had a dream last night shooting that Dual-raw video with 7D. This is serious stuff.

I personally appreciate Alex's great job and his daring thought, which I think quite fun, and the whitepaper is really well written(though a little beyond me). However, I do notice that this setting only works with iso100, if it can be extended to other ISOs will be a genuine plus.

Sorry if I missed it...but....Is there a noob guide on how to implement this hack on the 7d? My guess is that you'll need the original Magic Lantern firmware and just copy and paste to some bin files.. I know, I know...we're not worthy..but please, point us in the right direction..Thank You.

You'll either have to compile yourself, or wait for someone to release the updated autoexec.bin for 7D. You'll need both the dual_iso modules and the autoexec.bin

I'm finding it difficult to properly set exposure,

Set your base ISO for the highlights and the recovery ISO for the shadows.

Thanks Brapodam.. I guess I'll have to wait then...

@dubzeebass: can you upload a sample? (less than 1 second of video, if possible).

Did it work better with a previous version?

Why can't the 5D Mark II get Dual ISO function, what the difference in 7D that allow it to function?

Hi guys,
to work with raw2dng_shadow050.exe on wine in osx,
when the terminal tells me "usage:

Z:\Users\Seba\Desktop\Raw\raw2dng_shadow050.exe file.raw [prefix]

=> will create prefix000000.dng, prefix0000001.dng and so on."

What should I do?

Thanks

Copy your RAW video file to a location you like. For you it will do in Z:\Users\Seba\Desktop\Raw\ and drag and drop this file onto raw2dng_shadow050.exe. After this step you will get a bunch of files in this very folder/directory for further processing.

Ciao, Walter

That works fine in Windows, I'm not sure about whether you can just use it like that if you have to run it using wine.

Normally what I'd do would be to run

Quote

wine ./raw2dng_shadow050.exe file.raw

Of course replace file.raw with whatever the filename is.

If you want a prefix to your dng files then put the prefix after the filename

Thanks for the correction!

Can,t wait for macversion converter so installed virtualbox and used Alex raw2dng converter. Some serious iso improvements here. Question. I get this famous pinkish cast when converting, how can I avoid it? Filmed in 3x crop mode but it shows otherwise as well.
Thanks!

Upload a short sample. I don't see it in any of my test files.

driftwood · « **Reply #163 on:** July 19, 2013, 11:59:04 AM »

a1ex, have you tried sampling more than 1 frame (i.e. two) during the interpolation and if so were there no averaging improvements? I know it would be more taxing but Id be interested to know what your findings were.

How about frame x {1 second in} (settled) - do the math - return to frame 0 / begin?

a1ex · « **Reply #164 on:** July 19, 2013, 12:02:14 PM »

I have to align the frames first, and since they contain motion, it's not trivial.

Danne · « **Reply #165 on:** July 19, 2013, 12:19:59 PM »

Sent you a pm with a short clip Alex. Sometimes 3x crop mode works fine with no pink cast, others it don,t. Hot pixels numbers skyrocket in the converter when pinkish. Normal filmings seems to work fine.

*update, just tried a regular 1920x1080 clip and pinkish unfortunately. Seems inconsistent on my camera. Or with the conversion.

a1ex · « **Reply #166 on:** July 19, 2013, 12:29:26 PM »

Updated raw2dng.exe in the first post, seems to be OK now.

Danne · « **Reply #167 on:** July 19, 2013, 12:33:57 PM »

wow, that,s fast. Gonna try it out immedietaly

Danne · « **Reply #168 on:** July 19, 2013, 12:43:14 PM »

Did you change the raw2dng.exe? I still get the skyrocket high hot pixel numbers and pinkish cast as before.
Thanks
/D

*update, worked with my latest moviefiles. Will try in 3x mode an also do a comparison. Will post it later tonight
Thanks

Works here. Cache issues when downloading?

Uploaded the same thing with another name: http://acoutts.com/a1ex/raw2dng_whitefix.exe

Nice Alex! Worked perfectly

I,ll post a comparison tonight.
Sweet

bumkicho · « **Reply #171 on:** July 19, 2013, 03:50:19 PM »

Is raw2dng_whitefix the latest raw2dng that handles dual iso raw files? Will it handle normal raw files as well?

I did a short test
the lighting conditions it was hardly

ISO100 looks the best there. What's the difference between external and internal?
