Photo Mechanic from Camerabits.com is what I use. They have a fully functioning 30 day trial. It is a powerful, fast tool for captioning and other metadata tagging.
You can have it automatically add copyright info as you download from your memory cards, batch caption, save templates for different customers.
It doesn’t do all the image editing stuff, just cropping and resizing, but it is very effective in what it does.
Thanks for the info on photo mechanic. If I have to pay I’ll just bite the bullet on Photoshop.
