Lightroom Classic: Guided upright doesn't work with some Leica DNG files

Converted to DNG? Or regular raw files?

My Sony ARW files working fine too.

@Rikk is there a way to enable any kind of logging in Lightroom? Also here is an example of the raw file I have issues with.

Please let me know if I can provide anything else to help with this issue.

Hi Rick,

I wonder, if you have a solution for the described issue in the meantime?

Best,

Monika

I can't reproduce the problem on my Mac running Big Sur and Lightroom Classic 10.1. Guided transform works as expected. Maybe you should try resetting the preferences.

Thanks for the tip and for checking though unfortunately this does not work for me. I have reset the preferences successfully but guided transform still does not work.

Any chance you could record a video showing the failure and post a link to it here?

@Rikk 

Someone else reported this issue with Leica DNG files.

Thanks - @rikk here's a link to a video - https://www.dropbox.com/s/c1dt2wrswb361o8/guided-transform-not-working.mov?dl=0. As you can see, I move the handles at the end of the lines but no transform takes place. I have been using this tool successfully for at least a couple of years and it only stopped working a few days ago when I upgraded to MacOS Big Sur. Somebody else mentioned above that they had experienced the same behaviour on Leica DNG files, and this is indeed a Leica DNG file but I have been doing the same thing successfully previous to this OS update so it was not a problem on Leica M10-R DNG files prior to this. I haven't installed any new firmware recently so the DNG files themselves have not changed. Thanks! 

I have just tested the same DNG file on another laptop, using Lightroom Classic 8.3.1 on MacOS 10.15.5 Catalina and the guided transform tool works fine so it doesn't appear to be a problem with the DNG file. One difference between the two seems to be that on the more recent version (the one that is not working) the 'Update' button above the 'Guided' button seems to be active, whereas on the older version it is not. Clicking the 'Update' button does not appear to do anything - I have no idea what it's for.

Thanks. Here's the link to the file on Dropbox: https://www.dropbox.com/s/0ud3v8mq821jiql/L1008375.DNG?dl=0

Thanks for checking, John. Good to know.

Guided Transform on my Windows 10 machine won't work on this image either. As I've many other dng files that work fine, must be something about support for the images from your Leica. Did monitor with Task Manager to ensure that it wasn't working. 

While not a solution, all the sliders work fine. 

Constrain crop had no effect. 

Auto did work to a degree but I wouldn't find the result acceptable without further adjustments. A Rotate of +.03 after Auto did give a fairly good though not great result. Attached. 

So another bug for Adobe to fix.  

Interesting that it does not work on Windows 10 either. This appears to be a new bug - it has been working on the same file in previous versions of Lightroom Classic. Thanks for your help. Over to Adobe!

Peter, 

Another go-around. 

As you are probably aware, DNG is only a pretend standard, like TIF. Otherwise you would not be having this problem as the Guided Transform works just fine with many other DNG formats. So I ran some tests, exporting the DNG as a DNG but without any success, the resultant files didn't work. However, exporting as a 16 bit TIF does enable the tool. A least one downside is that the file is now almost 6 times as large.  

Now here's the funny part. Exporting the new TIF as a DNG and then editing this DNG and everything is good. The Transform functions work just fine with this DNG. Well, sort of good, you still have a file that is 4 times as large as the original. 

I am not by any means a TIF expert so I don't know if there is any loss of quality in these DNG => TIF => DNG conversions. Viewing them in the Library module at 200% with the comparison tool, I couldn't see any differences.
