Canon Digital Lens Optimizer

[JohnMoyer]

It appears to me that zero might be Digital Lens Optimizer disable and one might be DLO enable. I am having difficulty finding where DLO amount is saved, but it is displayed by exiftool when it is in the dr4 file. Please let me know how I might gather helpful information.

Also, Canon_LightingOpt_0x000a might be 0 for disable, 1 for standard, and 2 for high DLO.

Excellent.  You say "might be", but if you know the digital lens optimizer settings for these files, and no other parameters were changed, then I would say this is a slam dunk.  I will name these tags DigitalLensOptimizerSetting and DigitalLensOptimizer and add them to ExifTool 12.53 unless I hear otherwise from you.
