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.

Not sure this is correct. A Tiff is not like a JPEG where curves are applied and information is destroyed. A 16 bit Tiff can hold all the information that a RAW file has and in my experience does not have to have a curve applied.

A gamma curve is applied, unless you instruct DPP to create a linear TIFF. Then you will see a very dark image. Also, a 16 bit TIFF would contain as much information as the converter permits, depending on the setting you chose.

Uh, excuse my ignorance but isn't there a gamma curve applied to anything we view on a monitor?

Wouldn't any converted RAW file contain as much information as the converter permits?

I don't see the point of your points.
