    @ExAr I suspect your comment was downvoted to oblivion because people didn't realize you're the OP and thought you were an LLM summarizer bot :(

      The comment reads like an LLM summary. And we don’t typically get an OP summary on a new post. Just post it and let people read it.

        HN appears to encourage it, because it shows a text box which becomes a top level comment when you submit, although it isn't obvious that will happen.

          Huh, that definitely explains it. I wonder how many people know that. In that case it's particularly unfortunate to downvote the OP simply for filling a field in the submission form! Sigh… I guess it's another case of LLMs having made the world a little worse for everybody.

            I don’t think it’s because the comment was submitted. I think it’s because it reads like LLM output.

            Personally, I’ve only ever provided a summary if I felt the headline wasn’t clear enough.

      That's perfectly ok, they're using HN almost exclusively for promotion. See comment/submission history.

        But the articles are well-researched, very high quality (the illustrations in particular are incredible), and in every way prime HN material, and there's no money involved as far as I can see. I definitely don't have any qualms about self-promotion of this sort of stuff.

    This article presents the inventive solutions Canon has found to shoot beams of light into the camera's viewfinder in order to light up individual autofocus points. Six different approaches are shown using six Canon DSLR models between 1994 and 2009.
