Talk:Continuous tone image

Pixels don't vary in infinite steps, although since most displays have more bit-depth than the human eye can perceive it will appear so. Matthias Alexander Jude Shapiro (talk) 18:54, 3 June 2013 (UTC)[reply]

"The most common continuous tone images are digital photographs" excludes "An example of a continuous-tone device is a CRT computer screen".. I cant get a point at all! What does term `continuous` can exactly mean? Does it mean `discrete` (finite variations)? Does it mean `analog` (infinite variations)?

This article is confusing. The first sentence describes halftone images as those containing only one color for monochromatic prints, but further down, says that B&W photographic film, a halftone medium, consists of two colors (not one). There is also no mention of photographic film negatives, whether B&W or color. Are the film negatives also halftone for B&W negatives, or combinations of 2 or 3 separate color halftones for color negatives? What about motion picture film? My understanding is that color motion picture film uses a combination of 2 or 3 colors, either additive or subtractive, as shown here https://wiki.riteme.site/wiki/List_of_color_film_systems, so is color motion picture film continuous tone for the additive methods, and halftone for the subtractive methods? Or is any type of film, whether still image or motion picture, whether B&W or color, and whether undeveloped or developed (i.e., negatives or prints), always based on halftones, no exceptions?

I'm not an expert on continuous tone images, but the other definitions I have found out there appear to directly contradict one of the key assertions of this post, which is that a regular photograph is a half-tone. The photograph is the very thing used as an example of a continuous-tone image on several other sites, the explanation being that the color on such a photograph is a continuously varying shade of a single color, e.g. for the black and white photo, black. I will not cite this page, and hope someone knowledgeable will fix it. Capouch (talk) 00:14, 30 November 2019 (UTC)[reply]

Assertions re film

In this edit, I placed a {{cn span}} tag. Some googling turned up Personnel, United States. Bureau of Naval (1963). Lithographer 3 & 2. U.S. Government Printing Office. p. 124. See the Kinds of film section on page 124 there for a contradiction in this source of unsupported assertions in the same paragraph where I placed the tag. See also WP:BURDEN and WP:DUE.

@Wtmitchell: Not really a contradiction, more a matter of scale and perspective. Technically, any kind of film has areas that are covered with silver halide crystals (or whatever they are after developing) and areas without. Black areas and white areas, just like with a halftone print (color film works similarly enough; slide film might be a different matter). But there are two important differences compared to a halftone print: 1) the patterns are not regular and 2) the crystals are so small you need a microscope to see them. I think the point is, that from a printer's perspective, the resolution of a photograph is so high that for all intents and purposes it can be considered continuous. A chemist at Kodak would disagree strongly, but within the scope of this article, that seems to be more of a "nice to know". Also pinging @N3362 and Capouch: just in case ... --El Grafo (talk) 10:54, 29 April 2022 (UTC)[reply]

I'm just noting here that I placed the {{cn span}} in passing when I noticed something which caught my eye. On a second look, I see that I must have missed the hatnote {{Unreferenced}} at the top of the article, which is a larger concern -- the tag I added probably ought to be removed in favor of that larger concern, and that ought to be addressed by someone other than me. Whatever regular editors more knowledgeable than I decide about this is OK with me. I'm removing this article from my watchlist, so please ping me if I need to comment further here.

German language version

The German language version of this article seems to be discussing a different topic. 76.149.22.159 (talk) 09:49, 20 October 2024 (UTC)[reply]
