FilmPhotography-DuaneHorne Posted April 30, 2008 Share Posted April 30, 2008 Hi, I just shot my first roll of the Efke IR. The results were poor. [Equipment Used: Mayama C220 TLR, Wratten 87 filter, Sekonic Light Meter.] [Exposure: ISO 3, f-22, bracket at +/-1 stop, the filter factor was not applied. I took the reading with existing light reading then bracketed.]...It looks like I should have increased the exposure by several stops. Any suggestions? I had the Kodak HIE down to a science. Please provide any help you can. Thanks Link to comment Share on other sites More sharing options...
FilmPhotography-DuaneHorne Posted April 30, 2008 Author Share Posted April 30, 2008 Hi, One more thing. When I used the Kodak HIE. I used a Canon Elan 7E. I shot it at ISO 100. What I did was to take the exposure without the filter with the camera's light meter. I made a mental note of the exposure setting. I added the filter, then set the camera on manual exposure, setting it for the exact readings I noted befor adding the filter. I would take three shots, one on the exact metered setting and then bracket 1 stop over and under. Link to comment Share on other sites More sharing options...
User_502260 Posted April 30, 2008 Share Posted April 30, 2008 The 87 is an infrared cut-off filter. It only allows IR light through. If you don't apply the filter factor you will not get much of an image. Link to comment Share on other sites More sharing options...
FilmPhotography-DuaneHorne Posted April 30, 2008 Author Share Posted April 30, 2008 Thanks Jeff, I guess the Kodak HIE was so sensative to the IR spectrum that this additional exposure was not required. Link to comment Share on other sites More sharing options...
habsphoto Posted May 1, 2008 Share Posted May 1, 2008 Actually your metering process should work fine, assuming you use a ASA that matches the film's sensitivity. I have found that ASA 1 or ASA "Half" is a better starting point than ASA 3. Also the halation and contrast was more HIE like if the film was pushed a stop from my normal HIE processing time. The gals at Freestyle were telling me that Efke takes overexposure very well, almost to an extreme. like f11 at 15 seconds... so you might want to bracket 1 & 2 over. Is your meter accurate at ASA 3, would be my other question. Outdoors in sun your exposure should be around 2 to 4 seconds at f8. So your exposure at f22 should have been on the order of 30 seconds... I have samples and tests on my Flickr page, under IR tests. check it out and let me know if it helps. http://www.flickr.com/photos/schafphoto/<div></div> Link to comment Share on other sites More sharing options...
FilmPhotography-DuaneHorne Posted May 5, 2008 Author Share Posted May 5, 2008 Steve, I think I know what I did wrong. I metered at iso 3 and had it processed at iso 3. duuuhhh.... I should have metered at 3 and processed at iso 100, or as you suggest, iso 200. Link to comment Share on other sites More sharing options...
