single black-and-white photographic negative via the direct photographic transfer of the negative onto lithographic printing plates. The process is a photographic variant of chromolithography (color lithography). Because no color information was preserved in the photographic process, the photographer would make detailed notes on the colors within the scene and use the notes to hand paint the negative before transferring the image through colored gels onto the printing plates.

Referenced by Mark Twain?[edit]

In "A Connecticut Yankee In King Arthur's Court", the narrator refers to having "Chromos" hung up on the walls of his house. Any chance he's referring to these things?

He was most likely referring to chromolithographs. - Salmanazar (talk) 17:16, 9 February 2009 (UTC)[reply]

Zürich[edit]

"Photochrom was developed in Zürich, hence its proper name being spelled without the final 'e,'"

This might need some further explanation; I'm still in the dark. Tombrabbin 09:38, 11 October 2007 (UTC)[reply]

People in Zürich write in German (and speak in Swiss German). "Chrom" is (I presume) the German spelling of what would probably be rendered in English as "chrome" (from the Greek for color). It is curious that they used "Photo" rather than "Foto" (which would be the German spelling of the Greek word for light - "Graph" is from the Greek for drawing, BTW)- but that may be the whole Swiss-German thing popping up. - I agree that the statement, as written, is rather cryptic. -- 23:36, 19 December 2007 (UTC)

"Photo" used to be a correct spelling in German up to 2006. 62.203.218.133 (talk) 21:27, 5 February 2009 (UTC)[reply]

Colorization?[edit]

The article does not make clear whether these images include those colors actually perceived by the camera, or whether the colors were chosen after the fact and added by the photographer. EikwaR (talk) 05:30, 19 December 2007 (UTC)[reply]

Yeah I was wondering that too. Is it the equivalent of a painter painting a colour picture from a black and white, assuming what colours go where, or a method of producing colour for tone variation in the black and white negative? 138.38.217.149 (talk) 11:25, 12 February 2008 (UTC)[reply]

Examination of the example images indicates that the colour was added after the fact. Shinobu (talk) 14:50, 23 October 2008 (UTC)[reply]

Authorized the one-penny postcard?[edit]

@When the US Congress authorized the one-penny postcard: What does this mean? Shinobu (talk) 14:50, 23 October 2008 (UTC)[reply]

I have hopefully explained this point now. Salmanazar (talk) 15:37, 27 October 2008 (UTC)[reply]

What is a penney in terms of cents? Xxanthippe (talk) 00:49, 1 February 2009 (UTC).[reply]

From Cent (United States coin): "The one-cent coin is often called a penny, but the U.S. Mint's official name for this coin is cent." Salmanazar (talk) 18:09, 1 February 2009 (UTC)[reply]

"Aäc"?[edit]

Where does the term Aäc come from? Is it just a fanciful name, or does it have some meaning (a word, an initialism, etc.)?

It's probably the original Swiss trademark, means nothing in German (apart from the prefix to a German town whose name means something like "mineral spring", I think) and whereas the umlaut on the second "a" suggests an acronym (otherwise how would you pronounce it? Ah-ek?) I have no idea what it could possibly stand for. --mikaul^talk 07:56, 8 August 2009 (UTC)[reply]

Change the Image?[edit]

A Photochrom image has become a featured image, and is currently (04:06, 30 November 2010 (UTC)) on the Main Page. In fact, it's how I found this article. Does anyone agree that we should replace the main image on this page with that one, File:Royal Avenue Belfast2.jpg? Quinxorin (talk) 04:06, 30 November 2010 (UTC)[reply]

"Photochrome" is usually something else[edit]

Judging by a Google Books search, "photochrome" is more often used in a different sense, perhaps something to do with coloured pigments found in biological organisms. Some kind of redirect might be in order. Equinox (talk) 12:23, 22 August 2015 (UTC)[reply]

A disambiguation at the top of the pape for photocromic and phytocrome seems reasonable. but neither article exists. OrganicEarth (talk) 21:03, 22 August 2015 (UTC)[reply]
