Any chance of dual ISO for the 50D?

Silkway · « **Reply #576 on:** August 12, 2013, 04:50:00 PM »

Hi

You haven't read how the Dual ISO feature works and how to process it, right?

Silkway · « **Reply #578 on:** August 12, 2013, 05:01:47 PM »

oh yeah sorry i have read the first post

i downloaded that 3 files tools

and i try to drag and drop CR2 file on the cr2hdr.exe icon

but the command dial says "it seems like it is not interlaced ISO"

and shuts down...

here what i got

Conversion works for me with my 6D files but i am not sure about the en result.
@A1ex:does the cr2hdr need to be changed with data from other cameras?
I would love to upload the dual iso file now but it's not possible at the moment.

Did you shoot in live view? If so, it doesn't work. Use photo mode only.

no dear sir Andy600

i shot via viewfinder of canon 50d

but it seems like there is not enough info for processing on too dark images. thats a reason it didnt convert. but other images who shot on bright areas with good highlights it is just perfect working!

Danne · « **Reply #583 on:** August 12, 2013, 06:27:40 PM »

Don,t shoot in too extreme situations. I got the same problems when shooting birds in very bright areas such as skies. Otherwise it,s fine

Can I please request that the EXE for CR2HDR be updated in the OP? Seems like it's an earlier build.

akumiszcza · « **Reply #585 on:** August 13, 2013, 12:46:39 AM »

I've noticed green cast in shadows and highlights after converting dual iso cr2 into dgn on Canon 50D.

Normal case:

without Dual ISO:

Extreme case:
cr2hdr.exe:

cr2hdr_exp.exe:

Is there some trick to remove green cast in ACR (in normal, not "extreme" cases at least)? Split toning won't do the trick. Setting WB sets it either for highlights and shadows or for middle parts.

Yea, I had some problem with green cast on 50D. I think some of the problem might be that 50D uses iso 100, 320, 640, etc NOT 100, 200, 400, 800, etc. Have to check it out and port to 600D and *maybe* eosM if the module loads with CMOS logging enabled.

Hi all.

Really new to this and I have a "dumb" question. I'm on Mac (Mountain Lion) I have the source code and pre-built toolchain. Could someone point me where to go from there. Not quite sure what to do with it to use my 5D2 .cr2 files and get cr2hdr working.

My mistake.

port install mercurial

SenorClean · « **Reply #592 on:** August 13, 2013, 03:48:35 AM »

Working great on my 6D - well done all!

If you look closely in extreme areas you can see some fringing/jaggies/moire - see my 100% crop here -> http://img19.imageshack.us/img19/3097/tbje.jpg

BUT it is a small price to pay for the results.

ilguercio · « **Reply #593 on:** August 13, 2013, 03:57:18 AM »

Which ISO did you set in camera and which in ML menu?

REDcineX · « **Reply #594 on:** August 13, 2013, 04:17:48 AM »

Aww..

"-bash: cr2hdr: command not found"

To back track a little further. When I do this line and of course the same line for raw2dng:
"Type 'make' then 'sudo ln -s cr2hdr /usr/bin/cr2hdr'."

Terminal says: "make: *** No targets specified and no makefile found. Stop."

1% · « **Reply #595 on:** August 13, 2013, 04:24:38 AM »

Download/build it. and run ./cr2hdr

600D photo mode is working. 600D has real iso 3200. LV too.

I can make inside the raw_rec and dual_iso module folder and modules + binaries come out.

REDcineX · « **Reply #596 on:** August 13, 2013, 04:49:51 AM »

The only other thing I might have done wrong was download the toolchain (mac version), renamed it gcc, and placed it inside the magic-lantern folder in Downloads. I used all your commands, Francis, after that to keep it consistent.

Francis · « **Reply #597 on:** August 13, 2013, 07:04:45 AM »

Sounds like you weren't in the right folder to build cr2hdr. You have to be in the directory containing the dual ISO code. It is in magic-lantern/modules/dual_iso

REDcineX · « **Reply #598 on:** August 13, 2013, 07:29:56 AM »

When I type "./magic-lantern/modules/dual_iso"
Terminal replies "-bash: ./magic-lantern/modules/dual_iso: is a directory"

I type "make" after cd to /dual_iso
Terminal replies "[ GCC ] cr2hdr

I know previously we said that 'auto' video mode would not be possible with dual iso as iso changes were needed.

Is it possible to have dual iso with 'auto video' exposure mode, but just changing shutter-speed/aperture? This would be a massive, massive help for my line of work!

In other news, my 5D3 arrived today! Just waiting for Transcend 1000x to arrive on Monday now.
