anamorphic | artifacts

in the three images below you see a photo which i took with the moment anamorphic lens, a google pixel 2 XL smartphone and the moment app, settings set to RAW. when photographing straight JPEGs i get a properly scaled image, but not so in RAW. this is just fine, since RAW is raw. however, you see artifacts in the RAW image at the bottom and right edges of the image. these artifacts are not visible when shooting JPEG or film.

this photo in low light at frankfurt main station does not stand out. it’s just a routine shot. top: RAW image 34 MB, below: stretched by factor 1.33 in its width, bottom: magnified artifact.
