Does anyone have an information about cleaning slides?

Contents 1 black & white 2 Introduction of term 'slide' 3 Requested move 3.1 Survey 4 dr5.com - Commercial link to be included?

[edit] black & white

why has this section gone in its entirety? If it's not gone somewhere useful I shall revert. Bob aka Linuxlad 07:13, 3 October 2005 (UTC)

Later, OK I've now reverted to last version by Linuxlad, to reinstate the B&W bit. This bit IS a 'pig's ear' I agree, but there should be some discussion of black and white film and B&W reversal - if not here, then on a link to another article.Linuxlad

I just agree : this black and white transparencies section is really important to the article. Ok, transparency is "easy" to understand : it is nothing more than a film sensible to different colors (magenta, cyan,yellow instead of red, green,blue). I have a question,though : is the film sensible to pure white (I mean, what do you get when you expose it, for instance, to sunlight) ? And how comes it is not sensible to darkness in a camera, since black is a combination of magenta+cyan+yellow ?

[edit] Introduction of term 'slide'

I have wikified this article slightly, but notice a strange introduction of the term 'slide' two thirds of the way through the article. This would be better up higher but my lack of subject knowledge prevents me really restructuring it. --Stevage 16:26, 26 November 2005 (UTC)

[edit] dr5.com - Commercial link to be included?

We (wife and I) don't understand why the last edit was deleted! We have been using dr5 for many years and this lab is THE only resource of it's kind in the traditional photo market. Agfaphoto is out of business and the labs left are running remaining scala with non-agfa chemistry. It is only fair to list this labs unique constitution to photography, if not list them as something unique. If you list the one lab you should allow the other. If not, delete all listed labs! Main has not hold on processing this film. There are several in Europe still running scala. Reversal film 19:02, 13 December 2006 (UTC) Rob

Regarding this edit; I treated this as linkspam (given the evidence, particularly as the entry for a Colorado-based company was posted via a Colorado-based IP.)

Following this discussion at my talk page, I decided to put the material back (minus the "improved" POV comment) and let others give their opinion as to whether it should remain. Fourohfour 19:54, 13 December 2006 (UTC)

Well, it is a process approaching obsolescence, so it is somewhat relevant given the few places that can handle it. That being said, it would be ideally placed in an article solely about the Scala process, although such an article does not yet exist. I'd say keep for now - I doubt there are many other places which will be able to claim the same and thus follow suit. Girolamo Savonarola 20:06, 13 December 2006 (UTC)

I find the link to be a purely commercial link in violation of wiki policy and removed it. SteveHopson 04:41, 20 December 2006 (UTC)

I disagree strongly to Hopsons action! dr5 is a completely unique photographic process. Hopson shows little photographic credibility. photographically speaking the work is at best Amateur. The link should be re-enstated. If this is the case 'NO' photographic lab should be listed, period!

I suggest re-submitting all commercial links via the talk page to determine if they should be included or not. This is normally a good idea anyway. Fourohfour 13:04, 21 December 2006 (UTC)

On another note: I Have used the service called dr5 [http:www.dr5.com dr5chrome]. This is a Process, like Kodachrome or E6 or C41. An article should be created about this process. The results are not less than spectacular. No other process produces images like this one. The process has been published by several national photographic magazines and has world-wide recognition. I am not associated with this lab other than having my own film processed in this very unique process. I have no other goal other than providing correct information. Rob, Colorado

If DR5 is a unique photographic process that varies significantly from existing ones, then I recommend you provide some references, which would strengthen the inclusion of dr5.com, and possibly provide a basis for a separate article describing this process. Fourohfour 13:04, 21 December 2006 (UTC)

The following are industry links or dr5 highlights;

http://www.rangefindermag.com/magazine/archives/Jan05/labpro.tml http://photo.net/bboard/q-and-a-fetch-msg?msg_id=009lRJ&tag= http://www.jandcphoto.com/ (industry link) http://www.rangefinderforum.com/forums/showthread.php?t=32927 http://www.shutterbug.net/techniques/film_processing/0205dr5/ http://www.freestylephoto.biz/e_main.php (industry link) http://dr5.com/what.html http://photography.about.com/od/choosingfilm/a/newfilms_4.htm There are many more examples, rob.

Reviewing those links, it appears that the DR5 process is a method of developing b/w negative film to render a positive image (thus mimicing reversal). As it is a development process, it does merit an article. What I would say is that the article should briefly mention it, with a link to an article (existent or not), and perhaps a see also to that same article. The lab should not be mentioned within the reversal film article, because it is not relevant to this topic. The DR5 itself shouldn't be mentioned much except as a reversal-like process, since it really isn't reversal film. Basically, make a quick mention and keep the company out of it (in this article). Thanks! Girolamo Savonarola 02:39, 27 December 2006 (UTC)

Girolamo; Just because you dont understand something doesnt mean something isnt valid! explain to us what photographic experience you have? Have you seen or processed film through the dr5 process? dr5 is a process unique to all reversal B&W processes. E6 is a reversal color process that processes many like films. Does this make E6 not worthy of an article? What about other photographic processes of old? I have been told by the creator of dr5 to drop the issue, that I can not convince the ignorant. ..are we all ignorant here?

If the posted articles, along with an internet search is not enough information,, maybe everyone at Wiki is photographically ignorant. This would include the 'so called' experts. Regards; rob, CO

Girolamo; if the process is proprietary, and if worthy of its own article, then the company/lab which developed it certainly is worthy of mention, as they are both notable and relevant on that basis alone.

Yes; I'm the person who originally removed the "commercial" link, but it seems now that DR5 really have done something genuinely notable, and are thus worthy of inclusion; albeit as part of an article on the DR5 process. Fourohfour 14:16, 4 January 2007 (UTC)

Fourohfour; Dr-5 is a unique proprietary B&W reversal process designed & formulated by David Wood, who will not license it to other labs (I tried several times). Yes, some of his customers are in the Denver metro area, since he moved his lab there from Los Angeles, so it makes sense that one of his local customers would mention it.

Alas, due to declining volumes of B&W negative and positive films, I believe that the dr-5 reversal process should remain in this Reversal film article. Discpad 11:19, 22 February 2007 (UTC) Dan Schwartz, Cherry Hill, NJ. Expresso@Snip.Net

Am I mistaken, or isn't it a bit unusual that external links be accessed by clicking on text that is part of the body of the article? They already are filed under external links at the end . And the part about 'many say more pleasing results', sounds a bit too unsubstantiated to be left as it is. I'llcorrect these too, because it looks too much like we are promoting these labs, but I'll leave the links at the end. Cleversnail 19:46, 9 August 2007 (UTC)
