Tonal quality and dynamic range in digital cameras Sort of ... I found some gaps but all in all very interesting read. Particulary the parts about setting up tonal curves to match well known curves or films. One missing bit (pun?) was the reason why low ISO generally has higher DR is becasue that is when the sensors is "filled" to capacity. Any additional exposure will cause 'defects' in the form of blooming spikes, anti-blooming circuitry licks in and can do stange things, etc. One thing that I have not seen (or done myself) is a detailed work up on the noise when going from raw linear data then through a non-linear transfer curve (like a gamma or "S" type curve). One of these days ... raw+JPEG photon transfer curves for each ISO just to put the lid on it. If only the E-P1 could be tethered then a simple script and the task is automated.
