Tom, it appears you got an almost identical result with your approach.
Perhaps my example was not a real good one for what I was trying to do.
My original thought was if the dynamic range is say 12 stops and the camera will only recognize 5-6 and I don't have my Grad NDs with me, what can I do?
Let's say white puffer clouds and dark rocks with shadow detail. If I expose for one, I was quite sure it would be a non-recoverable error at the other end. e.g., if the whites are blown, "Highlight" will not bring them back, if shadow detail is totally blown, "Shadows" will not bring it back. At least this has been my thinking up to this point.
Like I mentioned, maybe this was not a good example. Not enough dynamic range to demonstrate a need for blending. But then again, I am near the bottom of the learning curve on post processing so I might not have any idea what I am doing
The lanai, veranda, porch or whatever is screened top and sides. Here in Florida, the enclosure is called a cage. The bands you are seeing are shadows from the overhead beams.
Maybe like other scenarios, the poor cat can be mutilated in many ways
