Dave you have in the past asked for lens cap RAW files to take noise readings on. Are you able to make those same type of readings on TIFF files? If so would you please do RAW to TIFF conversions using Canon DPP, and 3rd party RAW converters like DCRAW and ACR and compare the noise readings?

I see that you do not understand what a DR of a sensor is. Those TIFF files would have a curve applied to them and in particular, the deep shadows would be cut.

In Canon DPP you can do a TIFF conversion without applying a curve.

Canon's DPP just cuts the deep shadows and the brightest highlights. The illusion of not so much noise comes from the fact that the evidence has been hidden (not in the RAW though - after the conversion).

For the 6D, Canon DPP shows 13 EV of dynamic range despite the noise being 'hidden'.
