When you “ingest” pictures, you can add detailed information to each image’s metadata, noting who shot it and where, plus keywords, contact info, and captions. Using Photo Mechanic’s Variables, you can automatically add info specific to each image. So put aperture or ISO info in the caption. Or, if you like, note the original file name so that if your file gets renamed along the way, you can check the metadata to help you locate the original. If you primarily use Photoshop, Photo Mechanic beats Bridge because of the extent to which you can control metadata and the speed at which it previews RAW files. Photo Mechanic also has a leg up on the organizing functions in Lightroom and Apple’s Aperture, which use proprietary databases.
