Good day, I am a current PC user who is heavily into digital photography. (Some side work as well as tons of home, vacation etc.) Anyway, I'm moving to a MAC after thinking about it for quite a few years actually! My primary concern is image management software. (It's Photoshop all the way for image editing of course). I use Imatch on the PC, and have never found anything better. My entire image database, over 20,000 or so images at this point, is categorized using Imatch's built in category system. (A tree like hiearichal structure that allows for assignment of multiple categoreis to images). I also export this category information into IPTC keywords and categories. I'm wondering if anyone is aware of an application that runs on OSX that would have the ability to read these IPTC keywords, and create a category like structure out of them when importing the image files. This is the one thing that is REALLY holding me back from making this switch, as I have spent a very long time creating this categorization structure. Unfortunately, most product web sites that I have found are not very informative when it comes to the gritty details on what their product will do. Thank you very much for any information you can provide.
