At this point, converting to DNG files is causing my workflow to seriously suffer because I don't know what pictures I am looking at. There has got to be a way to preview them!
What should I do?
IOS Widows 7, Vista Ultimate
DNG converter 6.4
Photoshop CS4 w/Camera Raw update
They can be shown via Bridge, or if you install a DNG viewing codec, in Windows - just make sure you update the previews or you'll be looking at "old news".
Google "DNG Codec"
