Here is a shadow detail. Left image is straight exposure and right image HDR from
three exposures. The HDR image has clearly better shadows and the single exposure is quite noisy. It has a lot of DR but at the expense of excessive noise.
Third image is somewhat more excessive noise reduction in LR.
In this case HDR may be a good solution. I made several exposures of this subject, with HDR on mind.
Erik, can you show a 100% view crop of shadow detail brightened in one of the sun shots to show how much meaningful detail is present? Those trailing RGB vertical bars on the shadow end graphed in Rawdigger screengrab is difficult for me to relate EV levels to reproducing what the human eyes see.
P.S. I appreciate the hard work and effort in your demonstrations and input on this subject.
