I'm not really sure who made the first sheet film. The Kodak no 1 camera was in 1888 is notable, but that was probably not the first sheet film? -- Egil 08:56 Mar 16, 2003 (UTC)
Taking picture on a paper negative is as old as Fox Talbot in fact Eastman invented the rollfilm : several pictures on a film. The no 1 and other early Kodak were reloaded in the factory the paper tape allowing the user to load his camera came later. -- Ericd 13:11 Mar 22, 2003 (UTC)
Is it really useful to have a list of all the films available on the market? -- Ericd 00:50, 9 Oct 2004 (UTC)

That's a really good idea, actually... I'll write up another section, and move the "list of films" to a separate article while I'm at it. Neckro 08:32, 22 Oct 2004 (UTC)
It turns out that the topic was already covered at Film format. I included some links to common film cartridges, however, and also moved the film list. While I was at it, I revised much of the article. neckro 23:25, 22 Oct 2004 (UTC)
"Photographic film is a sheet of plastic (polyester, celluloid (nitrocellulose) or cellulose acetate) coated with an emulsion containing light-sensitive silver halide salts (bonded by gelatin)"
Many vegeterians refuse to use photographic film for this reason. Why can't photographic film use synthetic gelatin?
because it doesn't exists... :( -- Henriquevicente 03:28, 28 February 2006 (UTC)
Invention commonly credited to Eastman, it was actually invented by David H. Houston in 1881. (Now if I could just recall the source...) Trekphiler 18:05, 17 December 2005 (UTC)
I created this section to collect a few films that are known for particular characteristics or history. I've listed Kodachrome for its long life, and Velvia because it just rocks. I've also listed Kodak Tmax p3200 and Ilford Delta 3200 as two similar films that can be pushed to very high EI ratings.
I'd like to fill the list out some more. I was wondering if anyone has any suggestions? Perhaps the most (widely) sold film or something. Was there any film that was instantly recognizable? e.g "I knew that photo was taken with X as soon as I saw it". I've only heard that said about Velvia so far. Any suggestions? Imroy 21:32, 11 February 2006 (UTC)
Is Solaris really a company? From what's available on the internet it looks like Solaris is just a product line of Ferrania (which is already listed in the Companies that manufacture photographic film section). Can some with actual knowledge confirm that Solaris is also a company? Thanks. Csabo 20:45, 5 June 2006 (UTC)
I think there should be somewhere in the article about how it compares with digital photography and how some have switched over.. or why some have switched over. Knuckles sonic8 17:51, 9 October 2006 (UTC)
Why was Film Camera merged into this article, vis-a-vis Digital camera? I am not a photography expert or even an enthusiast, but I must say I prefer film. Leaving all that aside, however, is Film Camera no longer considered notable enough even to have its own article?
What really wierded me out was a comment on another talk page where someone said "they still make 35mm film. hell, they EVEN still sell 35mm CAMERAS". As if the product were completely obsolete, and evidence that you can find almost anything online! So I went on Wikipedia to learn about the history of film cameras and their current availability, only to find... no page dedicated to the subject.
There's no point in being directed to 35 mm film if Nikon, Canon etc. have decided to stop making film cameras, and this info is buried on the relevant Wikipedia pages! Not to mention the fact that the article on film cameras redirects here and that the main page for 35 mm references camera film only in passing. You have to click on an orphaned subpage, 125 film which is the only page that has extensive info on film cameras in one place. Having info like this would help reassure me that my old Nikon is still serviceable.
Could someone with extensive film expertise Be Bold and remedy this? See Film Camera. The fact that Digital camera exists is an argument for the notability of what seems like a pretty broad topic (yes, I know, WP:EXISTS. --berr 216.15.63.67 ( talk) 12:24, 4 December 2009 (UTC)
The statement is made "Black-and-white reversal film exists, but is uncommon." It is/was a common motion picture format (ex. Kodak Tri-X and Plus-X who share confusingly similar names to their still camera negative counterparts.) I'll find some links to back this up, but the statement is confusing and false. Should it be removed or just a parenthetical exception added with a reference? The latter sounds messy, and the former sounds preferable to me, since the statement isn't necessarily an important one to make. (Is it really important that B&W reversal stills film is/was uncommon?) Micahmedia ( talk) 18:02, 12 March 2012 (UTC)
This list seems to be incomplete and out of order: Fotokemika Efke ceased production in 2012 (no official statement that I am aware of, only third party statements) Kentmere was acquired by Harmann/Ilford in 2007 but is still a separate production line and AFAIK still a separate company as well. Should it be mentioned? Filmotec (ex-ORWO) is missing. They are still in production. Inoviscoat makes film for Fotoimpex sold under the ADOX brand. Slavich (Borisoglebskaya Sloboda, Russia) is AFAIK still in production. For many of these I didn't find any official statements as sources. Can someone with deeper insight sort it out? -- NonesensE ( talk) 20:16, 4 April 2013 (UTC)

The section called Color makes this statement:
"By the 1970s color film predominated and the use of black-and-white film was increasingly confined to low-light and "art" photography and other niche applications."
This seems misleading. Large Hollywood features were switching over to color in the late forties. Unconquered 1947, Easter Parade 1948, Samson and Delilah 1949 were top grossers in color. The top ten American box office films of the fifties were all in color. Mainstream films in BW were rare in the Sixties, at least in the US. And this is not limited to the US. For example film industry in India moved to color during the sixties. Already in 1960 Mughal-e Azam was in color.
Maybe the above statement could be phrased better.

Very well. I'll not remove the text that does not have citations. I'll add the "challenge" to each and every line that does not have a citation citation needed and note that a challenged sentence can be removed at the discretion of any editor that sees fit to do so. At some point, this article will be made up to date and accurate with citations. The history and evolution of this article (I reviews the entire history from start up to the current state, and simply because it has been here without citations for so long, does not make it right to keep statements that do not have citations. How can anyone find and add citations to what's already been written? Better to start over and allow editors to find and add information from sources that can be cited. Xo-whiplock ( talk) 06:57, 8 August 2015 (UTC)
You all should read this: WP:DISRUPTSIGNS Note the part about citations needing to be part of your edits, and appearing to be helping when all you are doing is being disruptive. Nobody was editing this page or doing anything about the lack of citations until I came along. Then when I started to work on fixing the page, I get "disruptive editing" thrown at me by those who are being disruptive.

I moved two footnotes from the Reference section and created a new Notes section. However, I am at a loss to find a reference for either comment. All search engine references to Edward's Isochromatic Plates seem to point back to a version of this Wikipedia article on other websites. If anyone is aware of the original source, I'd be grateful if you'd add the reference. IMO, neither comment is very important and doesn't add to the understanding of the topic - e.g. the first note comparing the amount of film to the area of Wales, and I think the article would be improved by deleting the two comments if there are no objections. Thanks. N0TABENE ( talk) 05:22, 10 August 2015 (UTC)
For several years, the "History" section of this article has led off with a paragraph informing uninitiated readers that there was photography long before the introduction of film. It simply notes the three most commonly mentioned carrier media: the daguerreotype's silver surface, the paper negative and the glass plate. As this article is about photographic film in particular, not photography in general, it seems desirable to limit its general history of pre-film processes to an extremely summary overview such as that, while providing readers whose curiosity has been aroused with links to the Daguerreotype, Calotype and Photographic plate articles, along with the broad History of photography article link provided by the "See also" located immediately above.
Another editor recently expanded that paragraph with mention of the Niépce heliograph and some photochemical detail (unclear but apparently very erroneous) about the daguerreotype image, additions which I reverted, resulting in a dispute which has thus far generated heat but very little light. I contend that the addition of such specifics is undesirable in that context and invitingly opens the door to the piling on of other processes and other detail by other editors, transforming what is now an easily grasped introductory statement into yet another mini-history of early photographic processes, of which there are arguably too many in Wikipedia already.
Apart from my concrete objection to the scrambled daguerreotype information in the currently reverted addition, the dispute appears to boil down to a matter of conflicting opinion and judgment. Input from other interested editors might be helpful in resolving it and would be appreciated. AVarchaeologist ( talk) 12:28, 1 December 2015 (UTC)

While the citation added (Applied Optical Measurements, edited by Markus Lehner, Dieter Mewes) mentions Agfa 10E75 and 10E56 holographic films, it does not mention the resolution of the films nor the comparative to CCD sensors. Since the technical discussion of the particular film was tagged as unsourced several months ago, and there has been no verifiable citation, this content should be be deleted unless a verifiable source for that information is provided.

All search engine references to Edward's Isochromatic Plates seem to point back to a version of this Wikipedia article on other websites. If anyone is aware of the original source, I'd be grateful if you'd add the reference. IMO, neither comment is very important and doesn't add to the understanding of the topic - e.g. the first note comparing the amount of film to the area of Wales, and I think the article would be improved by deleting the two comments if there are no objections. Thanks. N0TABENE ( talk) 05:22, 10 August 2015 (UTC)
For several years, the "History" section of this article has led off with a paragraph informing uninitiated readers that there was photography long before the introduction of film. It simply notes the three most commonly mentioned carrier media: the daguerreotype's silver surface, the paper negative and the glass plate. As this article is about photographic film in particular, not photography in general, it seems desirable to limit its general history of pre-film processes to an extremely summary overview such as that, while providing readers whose curiosity has been aroused with links to the Daguerreotype, Calotype and Photographic plate articles, along with the broad History of photography article link provided by the "See also" located immediately above.
Another editor recently expanded that paragraph with mention of the Niépce heliograph and some photochemical detail (unclear but apparently very erroneous) about the daguerreotype image, additions which I reverted, resulting in a dispute which has thus far generated heat but very little light. I contend that the addition of such specifics is undesirable in that context and invitingly opens the door to the piling on of other processes and other detail by other editors, transforming what is now an easily grasped introductory statement into yet another mini-history of early photographic processes, of which there are arguably too many in Wikipedia already.
Apart from my concrete objection to the scrambled daguerreotype information in the currently reverted addition, the dispute appears to boil down to a matter of conflicting opinion and judgment. Input from other interested editors might be helpful in resolving it and would be appreciated. AVarchaeologist ( talk) 12:28, 1 December 2015 (UTC)

While the citation added (Applied Optical Measurements, edited by Markus Lehner, Dieter Mewes) mentions Agfa 10E75 and 10E56 holographic films, it does not mention the resolution of the films nor the comparative to CCD sensors. Since the technical discussion of the particular film was tagged as unsourced several months ago, and there has been no verifiable citation, this content should be be deleted unless a verifiable source for that information is provided.

Whence did you take the density equation: ? Since cannot be negative, density is limited to , which is wrong because it is defined on the interval .
The linear part of the H&D curve yields: . This should be the correct model.

What's missing here are the graphic films which were used in lithographic layouting. Incidentally, this used to be a huge market.
They had high resolution but only rendered black and white and no grey tones. Maikel ( talk) 09:27, 30 March 2021 (UTC)
