andy_evans Posted May 10, 2007 Share Posted May 10, 2007 Can infrared light penetrate Holga plastic? I have a bad feeling the answer will be yes. This may sound crazy, but I'm trying to simulate the look of military night-vision equipment. Do you remember the video recording of the rescue of Jessica Lynch, for example? Grainy infrared tonality, vignetting, and fairly lo-resolution. Holga would be perfect! As a secondary question, I'm having trouble finding development times for Rollei's IR film. The tech-sheet pdf doesn't include them, but indicates that rollei.com does. I couldn't find them at Rollei either. The tech-sheet warns that non-Maco developers will result in decreased quality. Does anyone know if this is definitely true, or just a case of a company pushing you to buy its product? Thanks in advance! Link to comment Share on other sites More sharing options...
evan_goulet Posted May 10, 2007 Share Posted May 10, 2007 I have seen IR photos done with the Holga. To me, the vignette looked even stronger than regular light, very high contrast. I don't think you will have a problem with IR getting through the body since it is really near-IR that you are recording. Link to comment Share on other sites More sharing options...
neilambrose Posted May 10, 2007 Share Posted May 10, 2007 <p>Infrared film (e.g. HIE) requires a light safe environment and has to be loaded in the dark. I don't know about yours, but my Holga isn't even lightsafe, let alone infrared safe. It lets in daylight all the time and would continually expose infrared film even when the shutter is closed. I suppose this could be controlled by masking the body with light blocking tape, but why? </p> <p>Surely its easier to get the effect you're describing in Photoshop? It would take about 2 minutes. There are even tutorial sites that show you how (it's a popular effect for videogame artists).</p> Link to comment Share on other sites More sharing options...
andy_evans Posted May 10, 2007 Author Share Posted May 10, 2007 Thanks, guys. I've actually had no light leak problems with my Holga, and I don't tape the back or the exposure number window. I'm not so experienced with Photoshop, but I could give that a shot. How can Photoshop interpret which subjects (living/dead/foliage/skin/sky) to render as bright (rich in infrared reflection)?

evan_goulet Posted May 10, 2007 Share Posted May 10, 2007 I would recommend taping the exposure window, especially with IR film. Link to comment Share on other sites More sharing options...
