Lightroom/Camera Raw: Underexposed images when using Auto DR on X-Pro2

Images that were taken using the Auto-DR feature of the X-Pro2 are displayed 1-2 stops underexposed. But it's working fine with X-Pro1 RAWs, so I assume this is a bug. And I would very much like it to go away.

Hello All,

We have debated this issue internally, and in the end we decided not to fix it for the primary reason than for any images shot with AutoDR enabled that have had the exposure adjusted to compensate, the opposite effect (over exposure) will occur. While some users may be fine with this, there are many who will not be. 

Regards,

- Chris

I’ve disabled AutoDR because of this. I wonder about the amount of affected users as I suspect I’m not the only one. Would love to enable it again. Anyway, it’ll be like you said: whatever you do, you’ll create a problem for part of the user base. Is it merely a question of adjusting exposure by a stop to get the right result (with John’s plugin for instance)?

Hi. Would you be able to post some Raw+JPEG examples I can download and use to confirm this behavior?

Dropbox or similar service is fine.

Thanks.

Chris, it's been 6+ months since your post recognizing the bug. Have y'all decided on implementing it yet in either Lightroom CC or Classic?

Just wondering if any progress had been made on this. Thanks!

Hi Chris, many thanks for your quick reply!

Of course, just took a few sample shots out of the window...: 
https://www.dropbox.com/sh/7lgvuarmrymcu05/AABPTxQFgWLc5qaw5Yle0isKa?dl=0

And here is how it looks in the LR comparison view:



Kind regards,
Stephan

P.S: I also added a folder with a comparison image from the X-Pro1 which demonstrates the correct behaviour

Hi Stephan. Apologies for the delayed response. 

I can confirm that there is a bug in how we handle the automatic DR setting for the X-Pro2/X-T2 cameras. Manual DR setting is OK.

The fix, while simple, will have the unfortunate effect of over exposing images that have already been corrected for this so we are deciding what the best course of action is. I don't have a solid answer on what we'll ultimately do if anything.

Thanks again for supplying the sample images.

Hi Chris, 

thanks for your answer. Being a software engineer myself, I already thought that you might run into this kind of problem.

Well if you're planning on releasing a new process version (like 2003-2010-2012...) in the near future, you could make the fix part of that and let the user decide which version of the image to keep in your before-after-screen.

If that's not possible... well, as for me: I'd like my pictures imported with the correct exposure shown, even if that means I have to manually re-adjust some hundred images.

But I'm sure you're already discussing all that...

Thank you and kind regards
Stephan

Hi, I got the same problem. Quite confusing till I found this discussion. Yes, when DR=auto, the issue comes. Hope can be fixed soon.

If necessary, I can provide samples as well.

It absolutely baffles me that apparently I'm the first one to report this bug through the proper official channels, while it's been the subject of lengthy threads on dpreview (see here https://www.dpreview.com/forums/post/58937274) and even mentioned in some guy's book about the X-T2... maybe this bug would have been fixed a long time ago if people spent less time posting in forums and writing about bugs in books and more time with actually reporting those bugs... ;-)

Thanks for getting a bug report in.

I too noticed the `problem` and after much searching just turned off Auto-DR, and only today thought about entering a bug report with adobe and found this.

Chris -or any other Adobe staff for that matter-, do you have any updates on this? Are you planning to update LR soon to compensate automagically for the Auto DR settings? If not, I know some workarounds, but would prefer to have LR handle this (just like it does with my X100F).

(Sorry if I've come late to the party but I only just bought an X-T2 and this was the first time I ran into it)

I also have the issue. One problem is that it is not consistent. I shot 4 images for focus stacking, all with the same shutter speed, aperture and ISO (full manual) and under identical lighting conditions. Two files were displayed properly in Camera RAW (and Bridge) and two were underexposed by 1 stop. All were shot with Auto DR. Forums talk about the camera LCD displaying the JPG while Camera RAW shows the RAW file (eventually). That is not relevant. Is there likely to be an update soon? My firmware is 5.00. You will see that the EXIF data shows identical exposure settings.

Just a further point. I don't have any other RAW conversion software, but I am on a Mac and both Finder's thumbnail on the RAW file and Preview's image are all correctly displayed.
I also shot some more images for focus stacking and all 7 display in Bridge/Camera RAW underexposed by 1 stop. I will now switch off Auto DR permanently (DR100) as I shoot predominantly in RAW. When I do shoot JPEGs I'll just have to remember to go back to Auto DR as the images - especially skin tones - are the better for it. Not an ideal solution by any means.

A further point which confirms the error in Camera RAW. When I set DR bracketing, the displayed RAW files in Camera Raw are clearly different but ALL the exif data listed is identical (including the Brightness Value) as far as I can see. When I view the files in Finder or Preview they display as identical. As I understand it, DR bracketing should only apply to JPEGs (similar to Exposure Bracketing). I'm with Stephan Kleinart. I would rather the issue was sorted even if it means me having to make one a 1 or 2 stop exposure adjustment to the affected images in my library.

Thanks for the sentiment. After more than a year of waiting and hoping, I've given up hope that this bug is ever going to be addressed and switched to Capture One, which handles Auto-DR in RAFs flawlessly.

Kind regards and the best of luck with LR

It's not a bug. It's the result of AutoDR's exposure adjustment.

My X-LR plugin is mainly for mapping film simulations to profiles, but the resolves the AutoDR issue by allowing the user to control how Fuji's DR values are mapped to the exposure setting.

For Fuji DR settings, the implementation in Camera Raw/LR adjusts baseline exposure to match (closely) in-camera JPEGs. In the case of the X-Pro2 and X-T2, we (unfortunately) missed including these models for the case where AutoDR is enabled on the camera.
