Can some one please explain this observation to me:
I took a flattened TIFF 16 image in CS6 and saved it with ZIP compression on my Mac computer.
I took the identical TIFF 16 image in LR4 and saved it with ZIP compression.
The results are as follows:
Size of original TIFF file: 83.1 MB
Size of TIFF saved with CS6 ZIP: 80.7 MB
Size of the same TIFF saved with LR4 ZIP: 69.7 MB
It's as if the LR4 version of ZIP compression works better than the CS6 version. Is this possible? I can't find any info on the internet to help me with this.
