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.

Yes I understand all that but my point was this happens with any file whether RAW, Tiff, Jpeg, etc. Your statement above implied there was something unique about Tiff files as far as gamma curves which appears to be moot because this applies to any image file viewed on a monitor. I don't understand how your statement is pertinent to the discussion.

It is right there, in gray. You cannot judge DR by the TIFF without knowing how it was produced. On the other hand, you can try to compare noise vs. detail, etc., but you do not really know whether you are comparing sensors of RAW converters. DXO does not convert.
