Hi, please pardon my lack of experience, but I can not figure out how to do this: I lost the Makernotes information in about 600 images dear to my heart. This was caused by Adobe Photoshop Elements 5.0, which deletes the Makernotes if you edit a JPEG file and save it (at least in the JPEG of my Pentax K100D dslr and others reportes in the forums). BTW: Version 6.0 does the same. So I am trying to put back essentially just one label LensType, because that is important to me. Alas, Makernotes can be written only as a block and I am asking how I should handle this task. Makernotes has lots of other information, too, that a specific to the image. I do not need those but do not want to create a messy situation and contradictions in the Metadata. Could I just copy the Makernotes from an intact file, zero out all fields and just keep LensType? How would I go about that. Or what would be the best way to put back the LensType field of Makernotes? Any help appreciated. Thanxx, Mixx

Thanks, Phil. Would you know by any chance if I can use that tag (XMP:Lens) in Lightroom? I can not try it anymore before I buy, my trial licence just expired. Thanxx, Mixx

Just for the record: Yes, Adobe Lightroom does display the XMP:Lens Tag, in fact this is the one it displays, not the Makernotes:LensType tag. Luckily, if the latter is set, so is the XM:Lens tag. Should you lose the Makernotes metadata (e.g. by editing and saving the image with Abode Photoshop Elements), you can set the XMP:Lens tag for all images in a directory tree by issuing exiftool -r -XMP:Lens="Your lens description" your_directory_tree Lightroom will display the lenstype after import or after re-reading the metadata from all the files. Thanxx, Mixx
