    Which camera are you using? FYI, some cameras' base ISO is 200, so you can't actually go down to ISO 100.

    better to post this in the canon forums actually

    but my base iso on my pentax k20d is 200 when i go to "increased dynamic range" mode - sounds like what flipfreak is describing here from what i've read from canon reviews.

    read the manual, and look for that function. canon is more user-friendly than that, isn't it?

    Press the ISO button on top. (there are 4 buttons on top, press the right one). Once you pressed that, the top LCD will blank out, leaving only the flash compensation and the ISO value. Use the dial on top of the shutter button to change the ISO setting. The bigger dial near the main LCD is used to change the flash compensation.

    If you switch on the Highlight Tone Priority, the lowest ISO you can use is ISO 200. You have to turn off Highlight Tone Priority to use ISO100
