I ended up buying Photoshop Lightroom and Elements and have been playing around with Raw files in LR quite a bit. According to my DSLR for dummies book, the author recommends converting Raw files to a Tiff format, as they have the least amount of compression.

Well I did some tweaks to about fifty shots in LR, then exported them as Tiff, uncompressed. My 10.2 meg Raw files turned into 57.1 meg Tiff files. Is this right?? At this rate and as many pictures that I’m taking, I’m going to need a lot more memory real quick. I was expecting the file size to go down, not be 5X larger….. .
