P: Converted DNGs from Canon 70D won't open

Adobe products wont open converted DNG files from Canon EOS 70D. Other RAW editors open it just fine. It happen because of "wrong" exif data. If you rename exif data from "Canon 70D" to for example "Canon 60D", it opens fine.

Hi Thobias, we've found the source of the problem. This will be fixed in an upcoming dot release. Sorry for not taking care of this sooner.

I have not been able to reproduce this problem.

How are you converting the 70D files to DNGs? App? Version? Options? Which Adobe products are you using to try to open the DNGs, and which Version?

Can you provide us with an example of one of the 70D CR2 files and the (unmodified) DNGs that won't open?

Thanks for your help,
David

I produce this DNG's from MLV files, which is new Magic Lantern RAW video file format. For extract this files I use MlRawViewer 1.4.3. (or 1.3.3.). If I try convert this DNG files in Adobe Digital Negative Converter, it writes error about wrong analysing the file. All other Adobe product's are unable to open this file at all. Other RAW editors, like Zoner Photo Studio 17,18 or XnView open it fine.

There is unmodified DNG:

My Adobe products are latest and I'm on Windows 10 Pro 64bit.

Hi Thobias, I thought this issue was about raw files from a Canon 70D. Is that not the case?

Yes it is. Exactly same workflow with different camera (like Canon 60D) works just fine. Only DNG files that contains metadata about Canon 70D not works on Adobe products.

There is more info about that here: http://www.magiclantern.fm/forum/inde...

My understanding is that DNG files containing the Camera model as 70D in the EXIF data, will not open with the latest Camera Raw build. They did open in the previous Camera Raw build. If you change the DNG's EXIF data for the model from 70D to 60D, it will open the file correctly with the new Camera Raw build.

That's right. There is probably something wrong with code.

Latest version of Camera RAW (9.3.0.506) is still not able to open DNG files that contains metadata from Canon EOS 70D. Adobe DNG Converter (9.3) is also not able to convert them.

Non Adobe product open that files just fine.

Here is another one - http://www.mediafire.com/view/mu347e5...

Opening in Camera Raw in PS 2015 CC says: "Could not complete your request because the file-format module cannot parse the file."
