Beginning in the 1880s, sepia was produced by adding a pigment, called sepia, made from the Sepia officinalis cuttlefish found in the English channel, [1] to the positive print of a photograph.

What do people thing of merging both selenium toning and sepia tone into this article? They're both types of print toning and there appears to be some redundant information repeated between the articles.
Alternatively - merge the short selenium toning article here with a redirect, strip much of sepia tone's generic information but leave it with the historical and pop-culture information. -- Imroy 22:56, 19 March 2007 (UTC)
I think it'd be nice if there were examples of toned prints using toners other than sepia. Thoughts?
The top picture is not sepia toned. Its (by the look and date) an albumen print, gold toned. This gives a similar colour. I guess but dont know that sepia toning dates from maybe 1910-1920 in common use. —Preceding unsigned comment added by Justinc ( talk • contribs) 23:54, 13 January 2008 (UTC)
“ | Sepia toning is done in two steps. First the image is soaked in a dilute bleach to remove pigment from the silver particles so the brown tones can be visible in even the darkest areas of the photograph. Incomplete bleaching will create a multi-toned image with black or very dark brown shadows
Except for polysulfide toners, sepia toning is done in three stages. First the print is soaked in a potassium ferricyanide bleach to re-convert the metallic silver to silver halide. The print is washed to remove excess potassium ferricyanide then immersed into a bath of toner, which converts the silver halides to silver sulfide. |

The above paragraphs, taken from the Sepia section of the article, directly contradict each other (two vs three steps). The more accurate paragraph should remain, while the other should be edited or removed. -- Shruti14 t c s 01:37, 2 April 2008 (UTC)
About the time of the merge, did the equations for applying sepia go missing? I can't find them on any current page on Wikipedia any more. Hullo exclamation mark ( talk) 13:25, 2 August 2009 (UTC)
Sepia-tone photographs were common in the Victorian & Edwardian eras; I'm interested in more precise dating: when did this come into common use & why, when did it fall out of favor & why? linas ( talk) 15:32, 20 February 2011 (UTC)

Moving this here due to unencyclopedic tone, lack of citations, and weird formatting. It feels as though the editor who added this had some useful information but didn't know how to furnish it. If we can get some sources on it, it would do to redo the selenium toning subheading to incorporate this.

After further looking into the matter, I was able to find this link, which specifies that selenium does indeed provide a rich black, and longer baths produce a muted rich brown, "reminiscent of warm Afga paper". Link: https://piezography.com/piezography/selenium/ I can't find info on the tests in photography publications, nor the museum gallery statistics, but being honest, that's probably because I didn't look very hard. Someone more familiar with how to do it right (rather than just how not to do it wrong) should probably integrate this information. Imroy seems to care about the article and be proficient in wiki markup, from what I'm seeing, so he may consider this a request that he take care of it. 47.224.217.211 ( talk) 19:41, 17 February 2021 (UTC)
