JPG or RAW?

Thought this little article on JPG may prove interesting

(One main point - only 11% of the Blue channel's luminosity is kept, Red 30%, Green 59%. With RAW you get 100% of each channel)

Thanks Matt - very interesting; hadn't bothered thinking about those little 8x8 or 16x16 blocks before! I use RAW anyway, and then save as a 16bit TIFF!

Very interesting. Thanks.
