Sites we'd recommend for information about digital imaging and
specific camera recommendations, reviews, etc. are dpreview,
imaging resource, dcresource, rob galbraith, and fred miranda.
There literally are too many others to list.
Our digital capture technology includes hardware and software from
Phase One and Canon. It's no surprise that we use Adobe
Photoshop 90% of the time for image post-processing and
manipulation. What we use the other 10% of the time is a secret.
Other software applications we use include Extensis Portfolio, Panic
Software's Transmit (Mac only) and FileBuddy from SkyTag (Mac
only).
