I am using LR2 and CS4. From LR, I view a 10 megapixel raw file (NEF) and then open it as a SmartObject in CS4. I make no changes to the image in CS4 but just save it. The resulting TIFF file is 20 times as large as the original RAW file - 189 MB vs 9 MB. What gives? Why does the TIFF need to be so huge?
Thanks,
Peter
