Talk:Dufaycolor

Two suggestions

1. The picture isn't that helpful, mainly because the resolution isn't big enough to make out the colour pattern and even if it were, it wouldn't be noticeable in the article, where it looks like just another picture. It would be better to display a zoomed in view where only a small part of a high-resolution picture is displayed, so the pattern is clearly visible.

2. It would be a good idea to point out the similarity of this method to the colour mask in modern digital cameras. — Preceding unsigned comment added by 80.114.146.117 (talk) 02:49, 30 May 2016 (UTC)

The picture is a very fine (although undesirably very late) example of the colour quality possible with Dufaycolor, and has the great merit that it was uploaded by the person who took it in 1956, with an unambiguous release of all rights into the public domain. I agree that a greatly enlarged view of the mosaic is highly desirable, but even the full-resolution version of this photo does not make its structure very clear; another source ought to be sought for that, and it should be used in addition to the current image, not as a replacement. A graphic representation of the pattern would do, and perhaps I will eventually create and upload one myself, or excavate my perfectly good but long-disused Bausch & Lomb microscope and photograph one of my own specimens through it, but don't hold your breath.

The resemblance of the Bayer mosaic in digital image sensors to Dufaycolor's reseau is actually rather remote, even though they both serve similar purposes. The Bayer pattern much more closely resembles that used in the British Paget process of the 1910s and early 1920s, and the virtually identical processes that succeeded it, although the overabundance of green filter elements which is the innovative feature of the Bayer pattern would produce very unacceptable overwhelmingly green results if used with a photographic emulsion in a traditional screen colour process. However, the RGB filter stripe layer in typical LCD panels, now mentioned in the article, very closely resembles the structure and scale of the Joly colour screen of the late 1890s, without the irregularities that plagued the Joly product, and would probably serve very nicely in any retro-tech colour photography experiment. 66.81.104.204 (talk) 10:45, 7 June 2017 (UTC)
