Canon 40D 100 ISO gone!

HI, I was at a photo lighting seminar yesterday and my Iso would not go to 100, it went to 200 up and the numbers were smaller that normal. There were several Canon photographers there that tried to figure it out, but we never did. Could someome offer some advice?

My camera is about 5 mths old.

You have either Highlight Tone Priority or Hi ISO Noise Reduction turned on...
(Sorry forget which one needs to be off...I think it's the HTP...)

That's why you can't hit ISO 100 and your display looks like 2oo instead of 200...

Follow the link and scroll down to Highlight Tone Priority. I think you have that turned on.

You have Highlight Tone Priority turned on, look in Custom Function II.
