Fall Color settings

This is my first year with the 20D and I'm excited about taking some fall color shots. Any tips on basic settings? Speed, ISO, DOF. Here's a shot I took yesterday...any comments? ISO100, 7.1 1/250

Looks good. I always shoot 100 ISO unless I am forced to move up, and always try to use F8 or so, if lighting permits. Nothing different for fall colors. The light is the important thing. If you shoot RAW, you can even warm up colors that were dull due to overcast conditions.

Try using a warming filter (aka enhancing filter). I find that an enhancing filter really punches up the fall reds and oranges.

I would suggest try underexposing your shots by half a stop or so. That would saturate the colors and also boost some contrast. I sometimes even try underexposing one full stop to get all the tones even esp if its a bright day. Ah and dont forget to use a CPL filter as well.
Hope this helps.

As some have mentioned, I always shoot at ISO 100 unless I need to bump it up. However, on a clear, sunny day, you only need to have it at ISO 100. I always have my CPL filter on my lens when I'm shooting on a bright, sunny day. I also agree with Daman in underexposing. I tend to underexpose one stop to save the highlight. I really hate when I have blown highlight from overexposure.
