    I have a Sigma SD9 and tried to get a IR filter to give a result.
    I read some time ago that IR was possible with the SD9 (but not all dslr`s)
    so i set up the tripod ,focused on target,largest apature,slowest speed,ISO 100 (slowest)
    put the IR filter on and continued to take the shots,after about 50 attempts at differant speeds ,
    bracketing everything ---i even tried "bulb"
    I failed to get anything but red noise.Any idea where i`m going wrong or is a limitation of the camera.
    Thanx Kim

    First things first - leave the filter off and put the camera in an dark room. Set it to a long exposure (to give you time) and press a button on your TV remote, pointed at the front of the lens. If you don't get a spot on the image, the camera doesn't see enough IR light.


    This post says that you won't have any luck, however.

    I tried this with my 20D and needed 4s at f2.8 with the ISO set to 3200.
