Re: G7X II - RAW into Lightroom question

Apologies for lack of clarity.

I shot some pics.

Then transferred the CR2s from the camera to the PC.

Then used the Canon software (which is unable to read the camera directly... strange) to convert the CR2s to

- 8 bit TIFFs "with EXIF"
- 16-bit TIFFs "without EXIF"

Then I opened all of the above TIFFs in Lightroom 6.5 and examined them. I could not see any difference between an 8 bit TIFF and a 16 bit TIFF, at 1:1 zoom level. Nor was there any difference in the detail which could be recovered from shadows or highlights.

There perhaps should be a difference because the CR2 should contain the full output of the A-D converter which is something like 12 bits. But I could not see any. I am a hardware/software developer and I know that with say a 14 bit ADC, unless you take huge care, the last few bits will be just noise...

Exporting the whole lot to jpegs produces almost the same size jpegs, too.
