Hi Mac,
Thanks for asking - it looks like the original TIFF file that I grabbed
must have already been saved with lwz compression. So, I did the
experiment again using a fresh scan of a different slide with the following
results:
TIFF: 56,264 kb
TIFF with lzw compression: 35,364 kb
JPG with Photoshop level 12: 18,453 kb
So, in both this case and the previous one, the JPG with level 12
compression is ~ 1/2 the size of a TIFF with lzw compression.
Thanks again for bringing my mistake to my attention,
Johnny
