What are the current processes called? Rmhermen 14:32 10 Jul 2003 (UTC)

Good question im not sure in English silver nitrate on gelatin or something like that ? Ericd 14:42 10 Jul 2003 (UTC)

Maybe simply silver nitrate process for B & W ? For color it's simple : C-41 for negative. E-6 or Kodachrome for slides. Ericd 14:45 10 Jul 2003 (UTC)

E-6 & C-41 are ISO standards. I think they have they origin in the Agfacolor ans Agfachrome processes (the Germans were on top in color process technology around 1940) like many German patent the Agfa processes became public domain after the WWII. Ericd 14:54 10 Jul 2003 (UTC)

Gelatin-Silver seems OK for B & W Ericd 20:35 10 Jul 2003 (UTC)

Yes, gelatin-silver (print) is the most commonly used terminology.

You can also further distinguish between the modern-day RC paper (Resin coated) and the historically older but still in use Baryta paper (no resin coating, baryta is the white layer between the paper and the image, enhances contrast.)

RC is the stuff you get for the day-to-day pictures (holiday pics etc) Baryta is more for the bigger formats, used by professionals, the paper is thicker, it contains more silver etc. So higher quality and price... Most musea demand Baryta prints because of their superior conservation characteristics

(edit: i'm not sure if i followed the right route to add this comment Rxke )

I don't think RC paper vs baryta make different processes except for washing this is the same process . But is there an article on photographic paper ? Ericd 17:05, 1 Aug 2004 (UTC)

Yes, of course.. I got carried away. They are of course the same processes.

There are multipul links to the collidation process. What should be done? Personally I do not think it accurate to have 4 seperate links to one process. -Vcelloho 19:49, 18 February 2007 (UTC)[reply]

What belongs here?[edit]

Category:Photographic processes[1] says it's list "describe(s) procedures by which light-sensitive materials are made to produce an image." and that List of photographic processes is "The main article for this category". I am rm'ing to this section entries that do not meet that definition:

Ink jet process of printing digital images
Giclee made up neologism, not a process
Iris print process of printing digital images
LightJet process of printing digital images
Vignetting creative effect

Abraham Lincoln Death Photo[edit]

Legitimate research needs to be done on an image that from analysis is very likely to be the last image taken of Lincoln. In 10 years NO ONE has provided ANY evidence this is fake. See video 9 Hours Before Death on UTube. Tina Glessnee

cleanup[edit]

as Fountains of Bryn Mawr noted ten years ago; a lot of these things still aren't photographic processes. I've removed a group of listings that don't match the definition of a photographic process.

Ghost photograph - A category of photograph
Jews pitch - chemical used in photography
Negative - The reverse of an image obtained during most processes
Color paper - could refer to anything
sepia paper - could refer to anything
sepia - A tone, not a process
Wax paper - not a process, usually used for baking
Salted paper - Another name for salt print (already listed); not a thing in it's own right
Photo instrumentation - using information obtained from an image for research
Phototype - is a broad term that probably means Photogravure (already listed)
Palladium Print - Palladiotype (already listed)

There's a lot of duplicates and errors still listed, some things that i'm doubtful that they even exist, if they did they must be from nineteenth century literature. really the redlinks should be cited or removed where possible. --Solarence (talk) 18:28, 16 December 2019 (UTC)[reply]

More errors: Far over 90% of this list are not photographic processes (= developing processes), but either printing processes (all those -types and prints), printing materials (such as various papers), or base types (such as acetate film or various plates, at least those that don't have an emulsion type in their name). Kinemacolor is also not a development process but simply an early two-color predecessor to the Technicolor process of exposing several filmstrips in one camera. --2003:EF:13CE:6A10:B1F5:90E8:97E4:491D (talk) 10:35, 21 May 2020 (UTC)[reply]
