    Sigma SD1 Merrill IR WB - filters - postprocessing


    I have a Sigma SD1 Merrill and I am trying to take Color Infrared pictures to obtain an effect which looks like the 590nm SuperColor filter effect from Lifepixel.
    With the internal dustfilter in place, I tried different settings for White balance (standard settings and also Grey, Magenta, Cyan, Yellow and green Grass).

    After removing the internal dust filter, I have used several external filters (yellow, red and IR) and combined these tests with Red and Blue colorswapping in Gimp.

    Unfortunately none of the results looks promising.

    Can anyone give some advice?

    There's a short thread here: IR and HDR with SD1: Sigma Camera Talk Forum: Digital Photography Review where the guy says he got great results (unfortunately the links to the pics are broken) converting to B&W in SPP. I know that's not what you were after but perhaps you could blend the result with a colour image?

    You will need the dust cover off, it also acts as an IR filter.
