LR 4.1: "Convert to DNG" and "Update DNG preview & metadata" changes the "before" version

  • Problem
  • Updated 6 years ago
  • Acknowledged
Steps to reproduce:
1. Import a proprietary raw
2. set to black and white in develop (or make any other striking visual change)
3. show before/after view: before in color, after in b/w (ok)
4. Go to library, convert to DNG (I used 5.4 compatibility, no other options)
5. Go back to develop, show before/after view

Expected: before in color, after in b/w (as before)
Actual: The before version is in s/w too. It seems to have changed during DNG conversion.

In the same way:
6. Correct before version using history: "Copy to before" of import step
7. show before/after view: before in color, after in b/w (ok again)
8. Choose "update dng preview and metadata"

Expected: Nothing happens in LR (only the file is updated)
Actual: The "before" version is suddenly in s/w again. It seems to change during "update dng preview and metadata", too. Also, a dubious "from metadata" history entry is created - what does that mean?

LR 4.1 final 64 Bit, Win7.

Yes.

Not sure it's a bug. You may look at the DNG as new file.

I agree that it could be intended when converting to DNG. However, it should not occur for "update dng preview and metadata" - that is definitely a bug IMHO.
