Photoshop/Lightroom: DNG in photoshop colour space mismatch/issue

I have a weird issue using DNG in Photoshop. It looks like the DNG decoder in Photoshop (12.1 x86) is buggy.

If I open a DNG in Photoshop (Open... or from Lightroom) then the colour are just totally wrong.

If I export the SAME picture from Lightroom in TIFF or PSD, or if I add a custom external program in Lightroom with good settings (TIFF, 16b, ProRGD) then everything is correct.

This issue does NOT concern CR2 raw.

Have a look to the screen shot. In background you see the picture in Lightroom. It's ok. on the bottom/right you see the picture in Photoshop using "Edit in Photoshop CS5.1" Notice than the colour are weird and you get bad pixel on the right.
On the left you see the same picture exported by Lightroom and open in Photoshop.

Can anyone help me ?

Thanks.

Photoshop uses Camera RAW to decode DNGs and CR2s. If you turn off OpenGL does the problem go away?

You haven't said how the DNG was created, whether it is by the standalone DNG Converter, an import into LR, or a Save operation out of ACR or LR.

To narrow down if the problem is unique to your system or not, please post a CR2 and its corresponding DNG. Use YouSendIt.com if you don't have your own file-hosting website.

Also, what camera and versions of ACR, LR, are you using?

Hello,

First the details:
DNG are converted from CR2 by Lightroom.
OpenGL or not does not change anything.
Camera EOS 400D.
Lightroom 3.5 Mac x64
ACR (with Photoshop 12,1 x64, ACR 6.5)

I do not have the original CR2 of this particular picture anymore. I tried to shoot a picture do convert it into DNG using lightroom. Then I opened the CR2 and the DNG in Photoshop and compared.
The both picture looks good and the same.

So I am a bit lost... Why this particular DNG cause problem.

Steve. Are you related to Adobe ? Then yes, I could provide you this particular DNG itf it helps and if you do not share it with the world-

Thanks for you help

I think it would say Employee under my name if I worked for Adobe.

There are very knowledgeable people on this forum, but without a sample with the problem it is going to be hard to just guess what the problem is.

Is this the only DNG with the problem? Try changing the camera-profile of the DNG to Adobe Standard or if it already is to Camera Standard and see if anything changes. Also try making a virtual copy of the DNG in LR and resetting all the settings on that copy and see if it opens any differently.

So far, it is the only one I found out.

Ok. I could fix it.

I reset the settings in LR and then I did "Save DNG metadata and preview".

The picture is now correct but I obviously lost all my settings (contrast...).

The weird this is: Why does LR (with my dev settings in LR) display a correct image and export a correct TIFF but Photoshop display wrong thing..

Weird but fixed...

Thanks for you help.
