Do you use either ALO or HTP?

Re: Do you use either ALO or HTP?

Hi WilbaW,  I have to respectfully disagree with you on this one. I read a similar response to yours recently and would like to see an official explanation by Canon as to how this works! HTP seems more intelligent than simply underexposing a stop and then applying a curve to bump the shadow and midtone details back up to correct exposure. I have found it recovers highlight details in situations where, if your theory was correct, the rest of the image would be VASTLY underexposed and would require significant shadow recovery. i.e. if I was to expose for the highlights the rest of the image would be ridiculously underexposed, by far more than one stop.

With HTP turned on (on a Canon 80D) I can basically correctly expose for the image, generally, and HTP takes care of the highlights. It does a far better job than anything one could do after the event in software. The fact that it "gets it right" across a broad range of lighting conditions tells me that it is varying the amount of recovery to what is needed. There is no way it is simply recovering one stop.

Turning the feature off suddenly makes my camera's DR seem very noticeably reduced.
