Hi Chuck and C.H.,
The images that I post are placed in the Leica Users Group (LUG) gallery,
which will accept either tiff or jpeg images. The tiff image files are much
larger than the jpegs, hence I concluded that they contained more details,
etc. In looking at the images that I have posted recently, the tiff images
"appear to me" to be of better quality. Perhaps this is just a perception
that I have. For that reason, I have sometimes resisted changing them to
8-bit for final touch up.
Am I mistaken? Do our monitors and prints show only what would exist in an
8-bit image? I'm not enough of a techie to know how to evaluate this.
I also save all of my RAW files, so I can, and sometimes do start over when
I don't like my work in post-processing.
