Good infrared/near infrared camera
I have been experimenting with a Canon Powershot G5 with a Hoya R72
filter for "creative" (as opposed to "scientific") IR photography. ( Example: http://folk.uio.no/gisle/photo/ir.html ) The Canon G5 is IR sensitive, but not very much. Typical exposure times in bright sunlight is 1 second at f/2.0. I am not happy with the results. The long exposure time makes the images noisy and less than sharp. It also means that a tripod is mandatory. I am therefore thinking about getting a second (cheap) camera to be used for IR photography. I understand that "older" digital cameras, such as Canon Powershot G1 and Nikon Coolpix 775 had poorer "hot mirror" IR blocking filters than more recent models - so my plan is to get a second-hand 2 or 3 Mpx camera to be used mainly for shooting IR. I hope to find a camera that is sensitive enough to IR (or near IR) to allow me to stop down to f/5.6 or f/8 and shoot at 1/60 second or less in bright sunlight with a Hoya R72 or Wratten 88A filter in place. The problem: Does such a camera exist? I know Sony DSC-f707 and DSC-f717 (with the "nightshot" mode) are suitable - but these are 5 Mpx cameras and quite expensive second hand, and I don't like the way Sony has crippled nightshot mode. I am looking for alternatives to the Sonys. Are there any of the previous generation 2 and 3 Mpx P&S that bad enough IR blocking filter to allow them to be used at (say) f/5.6 and 1/60 sec. with an IR-pass filter in place? -- - gisle hannemyr [ gisle{at}hannemyr.no - http://folk.uio.no/gisle/ ] ================================================== ====================== «To live outside the law, you must be honest.» (Bob Dylan) |

Try to find a used Olympus C-2100UZ, which quite a few people like the IR photos they take, and because it has image stabalization, it means you can skip the tripod in some cases. Note, this is second hand, I haven't tried an IR filter on my C-2100UZ, just seen other people's work. -- Michael Meissner email: mrmnews@the-meissners.org http://www.the-meissners.org |
