I am not a photographer but I have been startled by how recent iPhone photos sometimes look better than what I saw when I took it. This article explains..

<div>Filmy-ness sounds like crude interpolation more than structure being imposed.</div>
<div><br>
</div>
<div>Suppose I had 1000 pictures of my dog in many lighting conditions and from different angles. Using photogrammetry reconstruction techniques these could be used to prepare a 3-d textured model of her. My iPhone could determine that the 1001st photo also
included her. It could then reference this model to enhance her image in the new context. Maybe inferring the light sources and ray tracing her at the required orientation and scale, but at a resolution far beyond what was in the photo. That would be more
art than a photo, but who cares about the truth anymore? Photos are to be staged!</div>

<div dir="ltr">Is that also why some of the older software for upscaling tricks the new pictures have a kind of saturated or filmy thing over them? or is that just from the particular Neural Networks or Ai models used? Still very impressive.</div>
