Re: 12 and 14 bits

Gabor, did you take into account that Lloyd Chambers was writing
about 14-bit NEFs?

"It translates into a breakthrough (for DSLRs) dynamic range of 13
stops at low ISO, where 14-bit lossless-compressed files are clearly
mandatory to maintain the full image potential."

But the D3X NEF files from imaging-resource seem to be 12-bit files
(at least the three or four I have downloaded).

Based on my (inferred) understanding of how the D3x works, I would agree that the difference between 12 and 14-bit mode might be critical at low ISO's, maybe less so at higher ISO's. Maybe Gabor's observations vs others are beginning to quantify the difference between 14-bit and 12-bit mode.
