"Thank you very much Todd for your response. Although I showed an example of some Sony files, my questions do not relate to Sony cameras as I work on files from all digital camera systems."   All digital camera sensors that I am aware of are at best 16 bit depth with most less at 14 or 12 bit depth. So again nothing to be gained by converting the file to 32 bit with the exception of Merge to HDR, which creates a 32 bit floating point DNG file. The 32 bit file file can be processed non-destructvely in LrC and ACR.   The DNG 32 bit floating point file can only be edited in LR or ACR with no capability to export as a 32 bit HDR file. If you need to edit the file in PS you have two options: 1) Apply your LR Develop module edits to the HDR DNG file and then use Edit in PS to open it as a 16 bit TIFF in PS. 2) Use LR Edit In> Merge to HDR PRO in Photoshop to create a 32 bit HDR TIFF. ...

The Sony A7 R2 ARW files are 14 bit depth so there is no benefit to converting them to 32 bit. LrC and ACR Merge to HDR create 32 bit floating point DNG files. They do benefit from the higher bit depth since the dynamic range has been increased by using bracketed image files.   ... View more

I can confirm the behavior you are seeing when the external drives are disconnected. It's apparently by design with the LrC catalog only recording the assigned drive letter and not the drive name. I'm going to change this post to an Idea requesting that the LrC catalog file on Windows systems also record the drive name. I believe that is how it currently works on Mac systems, but don't have one to test.   ... View more

"Yes, that might be causing it as well. I'm just not keen on creating individual drive letters for all my external drives to only make LrC happy."   On a Windows system that's the only way you can assign a name to a drive. If you start with M: that gives you 14 unique drives and the ability to plug in up to 9 non-named external drives without interfering with the named drives. That's why I asked, "How many external USB drives and/or other devices are you using?" ... View more

"I wondered if drive name retention only worked with USB drives, so I attached a USB drive with some photos and imported them. That drive did retain its name (and letter) when removed and the original "Personal-1" SATA drive suddenly displayed its full name and letter (hmm, ...interesting). But as soon as I closed and re-opened LR everything was back to displaying drive letters only."   I tried this on my Windows 10 system and after the LrC was closed and reopened the name (MyBook 2TB Win 10 Backup) and drive letter (S:) are both visible as in my original screenshot. What may be happening is that you are plugging in a device that is taking the drive letter H: assigned to your client drive. To prevent this from happening assign drive letters near the end of the alphabet perhaps starting with M:. How many external USB drives and/or other devices are you using?        ... View more

You can also simply uncheck 'Automatically write changes into XMP' in LrC's Catalog Settings and not use 'Save Metadata to file.' The request here applies to users who want the DNG file's XMP data to be updated as a secondary backup and for file sharing. ... View more

Camera Raw has a Preferences setting to create XMP sidecar files for DNG files. It shouldn't be too difficult to add this capability as a LrC Preferences option. This would speed DNG file backup updates after editing sessions since only the small XMP file has been changed. ... View more

That's actually a better way to find and delete the orphaned files. If unsure about certain files it allows you right-click on the file, select 'Go to Folder in Library,' and see them next to the other files in that folder.   In my procedure using the Import module the screenshot should show 'Don't Import Suspected Duplicates' as unchecked. I'll add a note to my screenshot. ... View more

You can do this using the LrC Import module with the below settings. It will take some time to run so be patient and it should reveal the files you Removd from LrC, but not from disk. Be careful that there might be files you want to keep that were never imported into LrC. So check them first in the Import module grid view and uncheck those you want to keep. I found 16 files, which I added back (Add) to LrC.   ... View more

So you should expect around a factor of 10 increase in filesize for the enhance details operation. Nothing you can really do about this. It is a direct consequence of what you are asking the computer to do. By @Jao vdL   Actually you do have an option that will reduce the Enhaced DNG file size and while retaining most of its benefits. Export the file to Lossy DNG file format and it will reduce the Enhanced DNG file size to about 1/10th its size. I use Lossy DNG file format for large panorama and HDR DNG files and 99% of them show no visual difference when compared at 100% Zoom view. As long as you keep the original raw file you are future proofed if you later find an issue with the Lossy DNG rendering or the Enhanced Details tool is updated. It's a bit of a technical hypocrisy, but if the visual rendering is the same you can save a heck of a lot of disk space!

Rikk, here's a link to the CR2 file. I found a CR2 file shot with this lens on a Canon EOS 70D APS-C crop body and it does not exhibit the issue.

I'm using LrC 11.1 on a Windows 10 system with Canon 8-15mm F4 Fisheye USM lens and Canon EOS 5D MKII camera. When processing a CR2 file in Camera 14.1with Photo> Enhance> Super Resolution the resulting DNG file has a circular negative vigenette applied. I tried with GPU both enabled and disabled with the same results. Both Camera Raw 14.1 and Lightroom Classic 11.1 produce a DNG file with the same circular negative vigenette as shown below. If the raw file is exported to a TIFF file it does not exhibit the vignetting when applying Enhance Super Resoltution. It only happens with raw CR2 files.   ... View more
