Adobe Lightroom and Fuji X-Pro2's DR photos

Yes, Auto is more convenient but Adobe doesn't handle it.  But my point is that all the discussion, above, about Adobe and Camera manufacturers doing something mutually compatible isn't the point in this situation, since Adobe can handle Fuji DR numbered modes.

I've never heard an explanation about why Auto-DR isn't handled.  Maybe the DR200 and DR400 that are recorded as the on-the-fly-selected DR mode when Auto is in effect aren't actually 100, 200 or 400, but something partially in between, like a DR250 or DR375 which Adobe can't guess the precise parameters of Fuji's conversion so doesn't try.

This is a user to user forum. We are all just users like yourself and have no connection to Adobe as far as employment is concerned. But it wouldn't do any good for Adobe to talk to Fuji. Fuji has created their file format and have probably provided software to enable you to edit those raw images and read all of those settings. They aren't concerned about compatibility with Adobe software. This isn't a problem unique to Fuji cameras. This is a general problem with all raw files from all camera makers. This is why Lightroom has to be updated to support every new camera that takes raw images. Adobe has developed the DNG file format to standardize raw file storage. A couple of camera makers have  adopted it as an alternative file format. But, generally speaking, it just isn't going to happen until camera users are somehow able to apply enough pressure to the manufacturers to convince them to adopt a standard file format. Until then, it's business as usual as I have explained in my other answer.

There are a lot of users who share your same frustration. I use Nikon cameras. Their term for dynamic range is Active D-lighting. Since I use Lightroom I have not used that feature in my camera. Canon users have the same issue but I don't know what they call the feature.
