Post-Processing RAW vs Post-Processing TIFF

The Delkin USB bridge can do this:

From the specs, it is a USB 1.1 device, so I can't imagine using it in the
field, since it would be slow and your camera would be unavailable while the
copying is going on. When speed matters, I shoot with multiple cards, and when
I'm shooting with the 2nd card, I am transfering the contents of the 1st card
to my portable hard drive (CompactDrive).

With the high end Nikon and Canon DSLRs, they have an attachment that connects
via USB or firewire, and then in the background sends files via 802.11b/g
wirelessly to a server (such as a laptop).

 

PNG is a nice middle ground for locking in photoshop edits. Seems slow
writing but only a bit larger than RAW.

 

The slow encoding was a deliberate choice. PNG was intended for Web
use, where images are encoded (written) just once, but decoded thousands
or millions of times. Thus, it makes sense to us a compression method
that is slower to compress than decompress. It's less well suited to
your application, where you'll read the image few or no times.
