Randy: Any particular reason why you keep the RAW files in addition to the DNGs? Just curious.
Alison: About raw files not opening in CS4 - try updating photoshop. It might be that your camera is too new for Camera Raw to recognize your raw files.
Help->Updates (that's on a mac - it might be different on a pc)
If you have all updates, raw files should open automatically. You can import your jpegs and tiffs into Camera Raw in CS4 by going to Preferences-Camera Raw and tick the JPG and TIFF boxes. Hope that helps!
I do pretty much what Katrina does. Just not that advanced. But I'm learning! I usually add an action or tweak manually in Photoshop if I'm converting to BW. But I'm longing for the new Totally Rad Lightroom presets! Has anyone tried them?
Also, I almost never save a jpeg. If I'm doing a layout, I don't bother saving the jpeg in Photoshop after I've dragged it onto my layout. I pretty much think that I can redo everything I did at a later time if I want to print it out. It saves a lot of space that way. That's another amazing thing about Lightroom. You can tweak all you want, but the RAW/DNG will remain the same quality, and you can undo at any time. (Or so I have understood it?)
If I want to be sure I can quickly find a photo I've scrapped, I add a
scrapped keyword to it in lightroom to easily find it later. I also have a
to scrap keyword for photos I really want to scrap.
