I didn't see any invented "new details" in the article's iPhone photos. Phones have small sensors and crap lenses, so they ramp up noise reduction and sharpness to make up for it. Turn up the ISO and max out the NR on the Fujifilm and the results would be nearly as bad.
- wombat_trouble 4y agoI see invented texture and layering here: https://yager.io/comp/mi.jpeg https://yager.io/comp/mi.jpeg
- kaba0 4y agoThat seems just like edge sharpening.
- jefftk 4y agoIt's pretty hard to tell without knowing what sort of image was input to the computational photography process
- MichaelZuo 4y agoThe actual image is right below it in the post.
- jefftk 4y agoThat's the image captured by a different camera (it's labeled "Fujifilm X-T5" and is from a different angle). The input I'm interested here is what the phone camera's sensor received prior to processing.
- MichaelZuo 4y agoHe mentions that the phone did display something close to that for a brief moment.
- wyager 4y agoThe text looks qualitatively very little like the true text. Almost all details of the text (including shape of strokes!) are hallucinated by the iPhone. I could import the X-T5 photo into lightroom or whatever and crank NR all the way up, and I don't think it would look anything like the iPhone image. Also, the less-processed image on the iPhone (which you see for a split second) looked fine, so there wasn't enough noise to justify this level of "correction". My guess is the iPhone got confused by the texture of the anodized aluminum.
