Photo Mechanic +1+1+1+1+1+1+1+1+1+1
Everyone has heard me say it more than once, that PhoMech is stellar. It bears repeating, perhaps?
PhoMech's file naming feature is impressive. You can use all kinds of exif in the naming string, if desired. Also date formats, random numbers, and more.
PhoMech can display your choice of exif for each photo in the info panel. Or under the thumbnails.
It has excellent tagging, colour classing for culls and sorts. You can display contact sheets according to type (nef, jpg) or colour or a chosen exif variable. Favorite naming strings can be saved as presets. The IPTC/keyword stationery is easy to use and nicely laid out. There is a side-by-side comparison feature for choosing the best version of a photo.
For example, in folder contact sheet I tag the photos I want to work on, display in a tag-only contact sheet and then send each photo to my favorite converter/editor with a keystroke.
PhoMech also permits cropping and conversions from raw to jpg or tiff. And has a watermark tool. Very handy for quick web displays after the raw has returned from the editor.
There is a nice PhoMech forum for asking questions, and the PhoMech team is very responsive
I think they are working on a cataloguing feature, but that does not interest me currently.
