Hi Dear PN Members, I am extremely interested in Digital Infrared Photography; I have been trying to do that for sometime now without any rewarding results. I’ve got the Cokin P007 Infrared (equivalent to the KODAK 89B 720nm), that I have used along with unconverted Canon 350D & 7D. I have made a simple test to see if these cameras are IR sensitive (using the TV Remote Control) and both cameras detected and recorded the IR light emitted from the RC. Shot in RAW+JPG formats, using the 24-70mm f/2.8 L and prolonged exposures resulted in foliage appearing in grey tones and bleached white skies (unlike the expected result of white foliage against dark skies). Even after many trials with different exposure times, f numbers, manual white balance (using the grass to measure WB), different PS manipulations and conversions, the results were unfortunately disappointing and very far from being IR. Few questions: 1. Is it my fault, the camera’s, or the IR filter that I am not getting the desired result? 2. Using unconverted 350D or 7D, have anyone successfully produced IR photos using the Cokin P007 IR? If this is a filter problem, then I am left with the option of converting the old 350D to a full time IR camera against buying the expensive 77mm Hoya R72 Infrared Filter ($100), I am aware that with the later option I am going to lose the spontaneity due to prolonged exposures. Thank you in advance… Regards.
