Adobe Photoshop Lightroom 4 supports new lenses compared to earlier versions. I was hoping that it would change some of my lenses from 'Unknown Lens' to a specific model, but it did not. Synchronizing my whole collection with Scan for metadata changes does nothing either.
Is there a way to tell Lightroom to rebuild its lens database without removing and reimporting all the images AND without modifying my originals?
While on the topic of lens meta, is there a way to add my own recognition and correct errors? I have one lens which incorrectly shows up, one lens that is only recognized part of the time and one that was recognized exactly once. None of these images have EVER been edited or modified by any software. The directories are on a read-only file-system to avoid all accidental changes.
