Hello: Suddenly, when I am sending files from LR to CS5 and then editing, CS5 is saving the file as a 1.5GB Tiff. I then get an error message that the file is too big for tiff readers to view the file (I'm assuming LR). In addition to it taking FOREVER to save the file, it is indeed not able to send it back to LR. I know this is because of the ridiculous file size. So... why is it saving it as such a HUGE file (it never used to do this), and how do I fix it? It's a really big problem. Saving it as a compressed TIFF file doesn't change the size, either. The original files are anywhere from 4-8 MB.
