    question… iso 50 is an artificial software induced ISO setting?? I have been advised by 5D users to set 100 as default… comment?
    Also… understanding ISO… how can any photographer understand the D3s Iso capability of
    102,400…WTF? This is Star Trek territory :)

  • I haven’t received that advice, but I don’t really notice much difference in image quality. I’ll look into it. As for ISO 102,400 on the D3s, I have read that even higher ISO ratings are being designed.

    Another great tutorial as usual Peter. Question, your IR converted camera 10D? How, if at all, is the ISO effected with the IR conversion? Do you need to shoot with higher ISO?
    I’m thinking of purchasing a second hand camera to convert to shoot IR, any recommendations based on your experience with the 10D?
    Cheers Crispin.

  • ’ve found that noise is just as much an issue after the conversion to IR as before, so I do try to shoot as low as possible. The 10D only goes down to ISO 100, so it pretty much resides permanently there.
    Whichever DSLR you buy to get converted, make sure it actually can shoot in mono if you are going to get a B&W infra red filter inserted into the camera! And give serious thought to choosing a lens to send with the camera to get it calibrated after conversion. I’ve had sooo much trouble getting focused shots until the 24-70 started doing the job. (The camera was calibrated to an EF 50mm f1.8 by default.
    Camera Clinic in Melbourne are the only mob in Australia I know of who do conversions. I went with Life Pixel in the US. They have an excellent FAQ page here
