Talk:Color photography

message: I am very dissapointed to see that a lot of interesting historical information was removed while this was Wikipedia's Picture Of the Day.  See the diff between March 16 and 23 (about 10 edits) Link  ....  Also, as an example of really good and intersting information about history of color photography, please see  (Also, they have very good restorations of Proudskin's 100 year old color photographs as well, see ) .... We sorely need a GOOD history section for this article... Mdrejhon 02:15, 24 March 2007 (UTC)
replies: text: Huh? The title is "Color Photography," not "Color Still Photography." Technicolor is a process (actually a few processes) that deserves to be mentioned. —MiguelMunoz (talk) 20:32, 21 August 2010 (UTC)
thread_title:  Poor History Section 

message: I believe this is the single most extreme bit of nonsense I've seen in Wikipedia:
"the entire cone stalk is an interference transmission line which resonates at two frequencies"
I thought about editing it out but I couldn't decide where I'd stop. Maybe the whole Land section should be removed if someone can't make sense of this.  — Preceding unsigned comment added by 24.96.210.230 (talk) 04:58, 2 October 2015 (UTC)

message: This article needs a lot of work (or a lot of external links). I've added a bit of detail on screen-plate methods. Needs more on tri-camera and separation negative methods and on early colour print. Good descriptions of the (complications of) Kodachrome process and colour print film (C-41) are also needed somewhere. 80.177.213.144
:The references by Sipley and Coote contain an enormous amount of technical information about pre-Kodachrome color. I don't have time to summarize today, but if someone else wants to pursue this, I highly recommend those two sources (Coote's book was published in the UK, but I found it in a bookstore in Wisconsin-- the manager gave me a discount because it had sat unsold for so long!) -Rbean 20:04, 29 December 2005 (UTC)
thread_title:  Article work / external links 

message: "The first permanent color photo was taken in 1861 by the physicist James Clerk Maxwell."
when you follow the link for James Clerk Maxwell it describes the method for taking his photograph as being identical to the description "Other systems of color photography included that invented by Sergei Mikhailovich Prokudin-Gorskii, which involved three separate monochrome exposures ('separation negatives') of a still scene through red, green, and blue filters"
the method outlined as used by Prokudin-Gorskii couldnt have been invented by him as he wasn born til 1863.
Not sure if this is the correct section for this question.  Is the statement "Plastic is also less resistant to tears in comparison to paper" correct?  My experience is exactly the reverse, but maybe it's just me who finds the flex and stretch of plastic slips usually prevents them from tearing easily.  My experience with paper envelops is that, in comparison, the paper tears easily. JJ Bosch (talk) 13:21, 19 July 2011 (UTC)
thread_title:  conflicting dates / claims 

message: The articles Louis Ducos du Hauron and Timeline of photography technology claims this to be the oldest known color photograph (1872). Google for his name and you'll find more sources claiming him to be the inventor of color photography. Kricke 00:29, 18 August 2006 (UTC)
thread_title:  Inconsistant with other articles and webpages 

message: I moved the section formerly titled Inevitable impermanence of color photography controversy. To preserve or not to preserve. into the article Photograph conservation because the section was more about photography conservation in general than color photography in particular. -- mordel (talk) 16:50, 22 February 2008 (UTC)

thread_title:  The Miethe-Bermpohl Dreifarbenkamera 

message: I remember an old photography book belonging to my father, which briefly described a color photography scheme that uses black and white film and relies on interference.  The approach was, as I recall: thick emulsion on a transparent plate.  The plate was mounted with the emulsion against a mirror (mercury, I think), and exposed through the substrate.  The reflection would produce interference patterns in the film, resulting in dark and light layers after developing -- vaguely like a hologram I guess.  When mounted against a mirror (I think that's needed) and viewed in white light, you would see a color image.
Does anyone have information about this, or references?  It might make a good addition, if supported by sources.  Paul Koning (talk) 18:10, 26 May 2011 (UTC)
replies: text: At least a brief linked mention is coming soon. Because the process is out of the main line of the development of color photography, because the history section was already lengthy, and because the relevant section of the article on Gabriel Lippmann, the inventor, was not in fit condition to be linked to until fairly recently, it was intentionally omitted. But a paragraph at the end of the "early experiments" section, featuring Lippmann as the end of that extinct (or dormant) evolutionary line and making a less abrupt transition to the "three color" section, would not overburden this article. AVarchaeologist (talk) 21:00, 13 August 2011 (UTC)

text: It would be difficult, and one would need a coherent source.  White-light holograms do work this way, though.  The emulsion is thick enough, compared to the wavelength, that the silver is deposited in layers.  However, a red laser source results in a green hologram, as the emulsion shrinks.  You would need to expose in three different colors of laser light, about 1.5 times the desired red, green, and blue wavelengths. I presume a reference to white-light holograms would explain this.

thread_title:  Interference method of color photography? 

message: I reworded "end of the spectrum we call 'red'" to "red end of the spectrum" on the grounds that the former was redundant: this is the English encyclopedia, so naturally we can be expected to use English words without apology.
The change was reverted on the grounds that "red is not a wavelength".  However, I'm not seeing how this fact would favour one wording over the other: how does the fact that red is not a wavelength make "the end we call 'red'" preferable to "red end"?  --Doradus (talk) 16:14, 13 December 2011 (UTC)
replies: text: The reworded one might be better. I just really dislike the terminology associating wavelengths with colors directly, because its omnipresence has led almost everyone to have severe misconceptions about how color works. It would be better to just say “one type of cone cell is most sensitive to wavelengths in the range A–B, one type is most sensitive to wavelengths in the range C–D, etc.”, –jacobolus (t) 21:01, 13 December 2011 (UTC)

thread_title:  More photos needed in article 

message: I do not think these developing agents require individual articles, but instead could be discussed in a section here, or possible at another suitable location, possibly more chemistry related. Polyamorph (talk) 13:11, 14 July 2019 (UTC)
replies: text: I agree they don't need separate articles, but also they don't belong in this one.  So until someone finds a better place to merge them, let's leave them. Dicklyon (talk) 04:57, 22 July 2019 (UTC)

text: Probably better to merge these articles on developer with Photographic processing. Qono (talk) 17:01, 21 August 2019 (UTC)
replies: text: I suppose one article on all color developing agents could be done.  Otherwise, it seems like merging hydroquinone with the black and white photography article.  The different CD agents aren't all that different.  Is there a minimum size for an article that they don't meet?  Gah4 (talk) 00:40, 10 September 2019 (UTC)

text: There are no chemical reaction equations in Photographic processing, not even the reduction of silver halide to metallic silver.  Seems to me that should be fixed before adding anything requiring more detailed chemistry. Gah4 (talk) 00:43, 10 September 2019 (UTC)
replies: text: No more comments here, but they are now proposed for deletion as not notable?  Without them, we wouldn't have color photography. The are linked to from the description of the appropriate process article, such as C41 and E6, which have more detail than this article. It seems that this article is already plenty long enough, and already doesn't have much in actual chemistry. Gah4 (talk) 05:26, 10 January 2020 (UTC)
replies: text: I've removed the PROD tags.  How about you work out a place to merge these two?  Maybe just a new article on Color developer or something simple like that? Dicklyon (talk) 05:38, 10 January 2020 (UTC)

text:  Let's merge these to either the color processing section in Photographic processing or to the C-41 process article.  Which article to you prefer to merge these to? Qono (talk) 12:43, 10 January 2020 (UTC)
thread_title:  Proposed merge with [[Color Developing Agent 3]] and [[Color Developing Agent 4]] 

message: Thanks for closing the merger proposal.  I would note that since the merger started, the CD articles each got a  added, as most chemicals have.  These are useful to have, but would seem strange merged into another article. Especially all four of them. It seems that there is someone who goes around added then  to articles that need them. I didn't know about adding them. Gah4 (talk) 22:43, 20 March 2020 (UTC)

thread_title:  Really, really bad 

message: This article appears to have the flaw of heavily written from the perspective of the present, without consideration of the past. It describes plate photography; and then it immediately jumps to digital photography. What about film photography that dominated in the twentieth century?

replies: text: @Dogru144 If you look at the version history someone seems to have completely removed a huge chunk of the information on this page because it was insufficiently sourced, instead of just flagging it. Vitiia (talk) 08:49, 5 June 2024 (UTC)
