Hope this single sentence quotation isn’t too long for you:

“My core argument however and also how that discussion started, only was that noise isn’t part of the image by classical definition (independent on whether one wants to preserve it or not), but an artefact [sic].”

Are brush strokes in a painting not a “part of an image” according to this imaginary “classical definition”? Film isn’t just a means of capturing what is in front of you. The celluloid itself is the art piece.

You may say you are on the side of preserving supposed “artifacts,” but this faulty reasoning is what leads to James Cameron/Peter Jackson’s ridiculous DNR (people somehow ignored it, but The Beatles: Get Back was scrubbed to hell) or film stock being deprecated as an option for new productions (for instance, the studio forcing seasoned master DP Ed Lachman to shoot digitally on Dark Waters even though they had the budget for 35mm).
