Maggi, I need to take some time to use the P function well and Jackie, the same goes for the Auto Exposure bracketing. I could have used that last weekend but was too lazy to figure it out. Maybe when I go camping I'll spend some time with those. I use the Av setting a lot because I can choose my focal length and then it adjusts the rest. I was using the M function a lot but since I started using Av, I just use it when I don't get the results I want there. I think I said my camera was a Canon Rebel xi but that should have be xs.
