IR Filter + X100 = ...?

    A friend bought an infrared filter and some IR film for fun, and we were wondering if anything fun could be done with said IR filter and my X100. I have an adaptor so the filter will screw on... but will the sensor pick up infrared and render an image? Forget the meter, I can work around that.

    Just curious if anyone knows.

    Best try it and see, you can't do any harm. I got some interesting results using a 650nm filter on my dp2s.
    It'll depend on the filter cutoff (the usual is 720nm) and that of the x100's sensor. You may get nothing

    most digital cameras use some sort of IR blocking filter (I'm not smart enough to know why, but one would assume that is to make better non-IR photos) They don't block the full spectrum of infra-red light, though. Put it on and experiment.

    You will be needing exposures measured in seconds so use a tripod.

    Gotcha. Tripod is easy, I have that and a cable release. Ok, I'll give it a shot.

    This could be interesting.

    Welcome to Flickr!

    Here are some shots i managed to take with my x100+ Hoya HD R72 IR-Filter
    And my tripod+timer mode, a bright sunny winterday. Nice effect i think.
    Will be getting a x100s hopefully and use my filters again.

    Its really nice to see the effects from the backscreen at least in BW mode, if u like shoot that.
  7. Actually, the X100 can be used for handheld IR photography with an R72 filter ( 720 nm ). The sensor has a better than average sensitivity to IR. In fact since obtaining a Ricoh GR the R72 filter is permanently attached to my X100 ( also works with X100S/T). A tripod is also useful in some circumstances as depending on the position of the sun, a hot spot may be visible in the centre of the frame which can only be reduced or removed by the use of smaller apertures necessitating longer exposures. I generally use a tripod and 2 to 5 second exposures at f8 or 11, however I do also use much shorter exposures handheld and achieve good results. It is very important to set the white balance of some well illuminated foliage as for some reason I get better results from jpgs than from RAWs.

    As Chris said... the unconverted X100, handles IR photography really well.

    Infrared on the FujiX100...

    I use an 'unmodified' X100 for general work, but have found over the years, that the Fuji sensor is VERY sensitive to I.R. light. So much so that you can slap a Heliopan 715nm or Hoya 720nm (R72) onto the lens... do a custom White Balance of grass... set the aperture to f2... select a controllable hand held value (this was taken on 1/40 sec)... and let the ISO take care of itself on Intelligent... and away you go...

    If you want to use a tripod... the sky's the limit... literally..
