You could help yourself by forgetting all about dynamic range, which is a
term pertinent to thos who manufacture and design CCD type devices.
If you are a photographer all that should concern you is density range,
because that is the range that carries visual information from the original
scene.
Oops, forgot the link, FWIW...

Hi Laurie,
Dynamic range is, in our case, (dMax - dMin) / noise.
I guess I tend to want to stay away from that definition in part because I
am not really able to visualize it very well

Woops. This is what I tried to type:

I knew what you meant :-)
Dynamic range is, in our case, (dMax - dMin) / noise. Density range is
simply dMax - dMin. Dynamic range is the number of discernable values
within a density range (in our case). Density range is simply the max
density value you can get minus the minimum density value you can get.
This is
Since JPEG is lossless and TIFF is not, this is to be expected.
Don't you have this reversed? My understanding is that JPEG is lossy while
TIFF with LZW is lossless.
