Sorry - guess I should have added that info in the beginning.
I have a Cannon S5IS, and it does have options to change aperature, shutter speed, etc. I only got the camera in July, and haven't had enough time to dive in on learning the ins and outs of the camera. (I took photography in HS and college, but have used a P&S for a LONG time since then, and have forgotten alot!)
Thanks!
