Let's all count to 10.
Ted was very clear about the purpose of the OP:
It wasn't about what is and isn't artisitically valuable, and it wasn't about how to deal with lack of focus in postprocessing.Here's how to extract 1px data and thereby determine what was in focus and was not in focus.
I personally would have placed it in this forum as well. Analyzing what is and isn't in focus is often an important part of postprocessing. I can see new uses for it as well, e.g., to quickly check whether any new "AI" tool used for blurring accidentally blurred the wrong stuff. Would be a lot faster than pixel peeping.
It's not uncommon for postings to veer off into other topics. I think that's fine, as long as we recognize what the original topic was.
