I concur regards Merrill's DR advantage for both luminance and chroma; the evidence supports the physics at this point too.

Sorry, Tom, DR should only be expressed in terms of luminance.

No mention of chroma here, for example:

Have look at the section on digital cameras.

That it should... I'm afraid that my technical lexicon fails me but I'm sure that you comprehend what I'm hinting at (?);

All part of the forum game, eh? People use their own words to describe stuff and we get to guess what they meant . .

Foveon 1:1:1 sensors are a law unto themselves, they must be a nightmare to test DR!

At one time Foveon used to tell us stuff like that . . . before the great take-over!

"The typical dynamic range of the F7 is 61dB." (SD9 sensor white paper).

That would be 10.13 EV.

Bill Claff tested my SD9 using the Photon Transfer Curve method - it came out to 9 point something EV, not too shabby.
