Trying to use Prime in .cr2 dual iso files
« on: April 14, 2015, 04:21:56 AM »
Hi Everyone,

I am would like to use Prime noise reduction from DxO software with dual iso.CR2. I try prime reduction in DxO>export to Lightroom (with the pluging) in .DNG file>Export in Lightroom plugin cr2hdr v3.0 BETA3.
I have the following message: AglmportSession.addOnePhotoToLibrary: failed to import photo.
Is someone know if it could be possible to use that workflow to denois dual iso; I’m on 7D + canon 400mm f.4 and even with 100/800 dual iso, sometimes is very noisy, it would be great to be able to use Prime programme.

Thank you in advance and sorry for my poor English.

Last I heard, that DxO noise reduction only works with original camera files.

Dual ISO DNG is not original.

Yes this why I try firs to denoise with the original CR2 dual iso file then export in DNG in LR and finally export with cr2hdr. In this way I can denoise but cr2hdr can’t convert dual iso. But maybe cr2hdr can be coded to be able to conver an DNG Prime denoise dual iso file?

This research was done for this purpose: http://www.magiclantern.fm/forum/index.php?topic=10895

However, to my knowledge, there's no public code to create a CR2 yet (but you could ask @Marsblessed).
