I am looking for suggestions on keeping digital photos organized. Right now I have been creating a new folder on my external HD each time I download the images to my computer. Is there a better way to keep things organized? The second problem I have is previewing RAW format images (Nikon D70). No thumbnail image is available, which means I have to open them up in photoshop to see what I am looking at. Does RAW have any significant advantages over shooting in jpeg?
