Well, I can definitely see applications in science – ultra high resolution recording of type-specimens and museum objects come to mind. In art, I can see some curatorial processes such as restoration and authentication benefiting from this sort of imaging.
Also, although the images linked here are being dismissed as ‘boring passport photos’ by some, it’s possible (probable even) that they will come to be seen as works of art at some point. I mean, Gursky’s “Rhein II” is quite valuable now, so…
How about the creation of very detailed panoramas for teaching, study, or simple entertainment.
Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
