All you RAW addicts, don;t sneer at JPEG compression. An article in the 
latest issue of Science (Vol 312, Issue 5777) suggests that the eyes 
125,000,000 cones and rods activate only 1,200,000 individual fibers in 
the optic nerve. This is a 10 to 1 compression ratio.

If this is the case, then a 1.2 meg. RAW image contains all the 
information that the eye can see.

Makes one wonder about the race to higher and higher pixel counts.
