Camera Raw/Lightroom: Support for PhaseOne Trichromatic

I use a medium format system produced by Phase One, with their newest "Trichromatic" sensor -- a CFA unique to this sensor. With each passing update to Adobe Camera Raw (there have been three since this camera was released) I grow a little more desperate as it becomes clearer and clearer Adobe doesn't seem to have any sense of priority regarding raw developmentfor this camera system.

It's awkward on set and has unbalanced my post production workflow, not to be able to access raw data for my main work camera. Exporting TIFFs and PSDs from Capture One can only get me so far, and instances where I need raw data (like bracket stacking to HDR) it's not possible to obtain a quality match of real raws, since TIFFS and PSDs are merely instances of those files not containing all the data.

I understand the fractional volume of these systems on the market probably plays a role in how Adobe prioritizes ACR development...but it's a top tier professional system, and it really surprises me that over the past nine months Adobe hasn't figured out how to make heads or tails of these raws. I know the Adobe and Phase One teams have a communicative working relationship...so does anybody have insight or info on what might be causing the delay?

Pity that Phase One doesn't support dng in camera as it would give you out-of-the-box support.

Hi Richard,

Sorry these trichromatic image files aren't working correctly for you. In our testing thus far, sample files are opening just fine.

Are the files not opening in Camera Raw or rendering incorrectly?
Which version of Camera Raw do you have installed? 

Can you provide more info on what's not working for you, perhaps even provide a sample file or two for me to pass on to our engineers for further testing so we can investigate this?

Provide more information about your workflow, and what steps we can try to reproduce the issue you're seeing, and we'll see what we can do.

Get back to us when you can.
Regards,
Pete

Hi Pete, thanks for your reply! Unfortunately I am all up to date, but they've never worked for me nor have I seen the files work on any other Adobe Creative Cloud setup from any of my DITs on set, friends, etc. No one I know can access the files without Capture One.

My Adobe CC account on both computers I use the files on (a windows 7 desktop and a Windows 10 laptop) both show everything as fully up to date; however for some reason within the CC app there is no dropdown menu for ACR for me to determine the version number (just says "up to date") so if you can let me know the method to determine the current version I can let you know.

I'd be happy to send you sample RAWs also, just let me know the best way to do that as they are 100-120MB each and probably not uploadable here. it shouldn't be too hard to reproduce, simply trying to access the files in bridge or photoshop produces results for which I have attached screenshots. As you can see not only will it not preview the IIQs, but it cannot read almost any metadata from the file. FYI Bridge, Photoshop in these screenshots also updated to the most current versions.

Thanks for the detail Richard.

For checking Camera Raw version, you can see the steps to check the version here: https://helpx.adobe.com/photoshop/kb/uptodate.html#VerifyCR

For sharing some sample files with me, you can use either your Creative Cloud files share, or another cloud service such as Dropbox to provide a shareable link.

Let me know how that goes or if you have more questions. 
Regards,
Pete

Thanks Richard -- I'll pass this link to our engineering team to investigate further.. Will get back to you when I have more information to share. 

Sorry for the trouble opening the image files in the meantime.

Hi Richard,

Thank you for supplying the images. I have a preliminary implementation working for the camera, and would like to get an additional calibration image from you if possible.

Would you be able to upload an image made under incandescent lighting with a color checker in the scene?

Thanks,

- Chris

Chris,

Amazing! I have added the file you requested to the above folder, you will see it named very obviously. The file was provided to me by Digital Transitions LA as I didn't have a color checker handy but the file was produced in reference to this case. The image is lit with a Profoto strobe.

I think you may also find this expertly written blog post to be informative if you are interested in the differences between the CFA on this sensor and the standard 100MP back. You would be particularly interested in Parts II and III :-)

Richard, the most recent ACR update, 10.4, has preliminary support for this camera.

Gents, on behalf of the Phase One army, THANK YOU! I'd buy you a beer if I could :-) Any idea on when we might find this implemented in Lightroom as well? It seems to have its own discreet version of ACR, 10.4 doesn't recognize the files there...

Lightroom Classic and Lightroom CC did a release at the same time with the same support. You can see the versions required at the top of the page here:

Thanks Jeffrey, It wasn't registering in the CC app until I restarted the service. All works perfectly now!

I have updated all my Photoshop family yesterday and still can't open Achromatic IQ3 100 files. Neither by ACR nor by LR.

Isn't the Achromatic IQ3 100mp the b/w sensor?
