       | The same photographer has two other photographs[^1] which
       | previously were ranked highly in the contest. All seem to focus
       | on chemical reactions and are stunning.
       | 
       | Interestingly, the previous two--of a candle and match--used 2.5x
       | magnification, where as this one required 20x magnification,
       | which just goes to show as to how tiny the printer mechanics
       | really are.

         | Interesting, the Match Strike (2nd place in 2023) seems counter

         | When I first saw his inkjet shot I refused to believe it wasn't
         | completely CGI. So, I take it there is a degree of artistic
         | freedom to compose a shot that may not be indicative of the
         | actual subject? Then the line is drawn with AI enhancement?

             | 
             | For me, colour enhancements are expected, compositions is
             | where we leave reality. Either way, all of these images are
             | an amazing insight into a world too small to see with the

               | FWIW I'm an astrophotographer, and I don't really view 30

               | the outcome of a lengthy signals processing chain.
               | 
               | I suppose the question is where the line is drawn. Ten

               | Is there a difference? It's still a photometrically
               | correct capture of the scene, unless you're using narrow-
               | band filters or multispectral compositing you would see
               | the same if you had huge eyes. In the same way a stacked
               | smartphone photo is still a photo unless it's also using
               | AI, and even then AI denoisers are pretty much accepted
               | in photography as long as they don't meaningfully affect
               | the subject (as well as more traditional things like CPLs
               | or extra lighting).
               | 
               | Nothing in Nikon's challenge is natural, it's still a
               | photo as long as it represents something real.
