Compression in JPEG files in digital cameras

No it doesn't. Most cameras do NOT support TIFF. Many cameras support RAW.
Regardless, I agree with your RAW-versus-TIFF remark. I've only toyed
with those modes, briefly, and saw that the P850's RAW files averaged
around 9GB, but the TIFF's were all precisely 14,821KB.
Indicating a lack of compression and fixed length metadata (to the nearest KB
anyway).
By contrast, this digicam's largest JPEG images have been about 3.2GB,
with the vast majority under 3GB (all the way down to 538KB).
Funny ... my D200 supports JPEG and several modes right along side RAW.
However, I have never shot a single JPEG with this camera, so I can not tell
you how big the files are ;-)
