I have a few Lightroom 2 catalogs. My main catalog has has "write to XMP" turned on for a while, but just realized my other catalogs did not have this setting checked.
My Canon RAW file directories now get an XMP created when I and change a setting, but I have directories that are scanned film in TIFF format. These do not get an XMP file created. I used the "write data to metafile" function and still no XMP file created.
What's the deal? Are XMP and TIFF not compatible with Lightroom? Is this a flaw in LR2? Or is Lightroom writing the list of setting changes to the TIFF file? (that would be bad - I don't want that - I want to see the list of setting changes if imported again into LR).
