chris_sullivan1 Posted August 4, 2005 Share Posted August 4, 2005 I just shot my first roll of Kodak Ektachrome EIR infrared film through my m6. I shot it at 200 and used a yellow filter per Kodak's recommendations. After speaking with my former photo teacher, he said the yellow filter was supposed to keep my skies blue, but it didn't. The film was processed in E-6 and the entire roll turned out magenta. Even the leaders were magenta. I took the slides and scanned a few of them to make color adjustments in photoshop, and some turned out alright, but is this magenta normal, or did the lab foul something up? Variations between yellow filter and no filter were minimal. Thanks in advance for anyone able to shed some light on the subject. Below is a pic I was able to adjust in photoshop.<div></div> Link to comment Share on other sites More sharing options...
al_kaplan1 Posted August 4, 2005 Share Posted August 4, 2005 I think that Ektachrome Infrared is still designed for E-4 process chemicals, not E-6. Link to comment Share on other sites More sharing options...
terry_rory Posted August 4, 2005 Share Posted August 4, 2005 What effect were you hoping to acheive with IR in colour? I cannot see from your pic what the IR gives it. This may help you... http://www.naturfotograf.com/irfilters.html I am not sure what can be achieved that cannot be done on photoshop.<div></div> Link to comment Share on other sites More sharing options...
terry_rory Posted August 4, 2005 Share Posted August 4, 2005 totally wrong address there sorry. I was in another thread from some time ago in another window and downloaded someone elses picture by mistake. Apologies to whomever it belongs to.

c_d5 Posted August 4, 2005 Share Posted August 4, 2005 The new Kodak Ektachrome EIR infrared is a new film that can be process in E-6 or AR-5. Kodak manufacture this film because the conventional infrared slide film which had to be process in E-4 is too expensive. http://www.vividlight.com/articles/3113.htm Link to comment Share on other sites More sharing options...
william_john_smith Posted August 4, 2005 Share Posted August 4, 2005 Ektachrome EIR is an E-6 film, has been since 1985. E-4 process was stopped in 1985. There is only one lab that still does E-4, at least there was one in 2002. <BR>Do not process infrared film in labs using equipment with infrared sensors. The infrared sources used by photofinishers, such as night vision goggles, infrared cameras (used mostly on rack- and-tank machines), or infrared replenishment sensors (used on some roller- transport,continuous and minilab machines), will fog EIR Film.<BR>I would check with your lab, I bet they didn't turn off their infrared while doing your film and that is the problem.<BR> The filter to use for blue skys in the #12 Deep Yellow.

SolaresLarrave Posted August 5, 2005 Share Posted August 5, 2005 I was under the impression that the filter for this film is something like the #25 (which is red). Why use a yellow filter? Link to comment Share on other sites More sharing options...
william_john_smith Posted August 5, 2005 Share Posted August 5, 2005 Because a #12 Deep Yellow filter is the correct filter to use with Color Infrared film.<BR>With color infrared film all three layers are inherently sensitive to blue radiation. To limit the exposure of each layer of color infrared film to only its intended spectral region, a yellow filter (minus blue), such as a #12 Deep Yellow Filter (or equivalent), is always used over the camera lens. With the yellow filter in place, the layers act as though they are sensitive only to green, red, and infrared (all blue radiation is absorbed by the filter)<BR> A #25 Red filter works well with Black and White Infrared film but the topic here is color infrared film.

roger c Posted August 5, 2005 Share Posted August 5, 2005 The version that has been around for the last 10 years is E6 process. Use a deep yellow filter and set a hand meter to ISO 200 for perfect exposures. With TTL metering you'll have to experiment. <a href="http://www.peeble.com/eirpan.htm">Some EIR shots here</a>.

SolaresLarrave Posted August 5, 2005 Share Posted August 5, 2005 Well... I'm always learning. Now I realize I had my cables crossed when I got into this, and bought a filter good for black-and-white film when I have color stuff. Will orange do similarly? I also have a B&W brand filter in yellow... and it looks deeper than the Y2 I have for my SLR. I guess I can stack it on the #25 and see what happens.

al_kaplan1 Posted August 5, 2005 Share Posted August 5, 2005 The #12 filter, designed for B&W, works just fine with infrared color. Link to comment Share on other sites More sharing options...
william_john_smith Posted August 5, 2005 Share Posted August 5, 2005 The #12 Filter (minus blue) was originally designed for BOTH B&W and Color film haze penetration in aerial photography.<BR>As far as Color IR film goes, to quote Eastman-Kodak, "For outdoor use, a Kodak Wratten filter #12 ought to be used, although a #8,15 or 21 filter can be utilized for special effects. However, for scientific photography, where a "biological" color balance is necessary for consistent results, the #12 <I>must</I> be used."<BR>But then again that is from the company that makes the film so what do they know?

william_john_smith Posted August 5, 2005 Share Posted August 5, 2005 The #25 removes blue. If you don't want blue sky then use it. This filter is primarily used for haze penetration with B&W film, both infrared and conventional, nice black sky. Ansel Adams had one on his keychain, never left home without it!

vivek iyer Posted August 5, 2005 Share Posted August 5, 2005 Check to make sure: 1. The film came from a proper storage- heat can affect this film more than any others. Alos, don't bother wasting time on an outdated roll. 2. The lab that processed it follows what Kodak recommends, EXACTLY. Link to comment Share on other sites More sharing options...
chris_sullivan1 Posted August 5, 2005 Author Share Posted August 5, 2005 Thank you all for your responses. Based on the sample images everyone sent me, it is obvious there was something improperly done to my film. I'll give IR another try when I have another $40 to blow on a roll of film and processing. Until then, back to negatives. Link to comment Share on other sites More sharing options...
