I have the Canon Rebel XS and it has the option to choose from 7 focus points or to allow the camera to choose the focus points. The auto focus didn't always choose the correct subject and so I have been choosing my focus points manually for the last while. I have often wished that I could choose 2 or 3 focus points at a time, but of course the camera only lets you choose one manually.
Case and point, today I was taking a photo of the dog pulling a kid in the pond. Cloudy but fairly bright day. Went for an ISO of 200, and a shutter speed of 100 per second and an aperture of 5.4. I put my focus point on the kid and than took another photo with the focus point on the dog. When I got home I had only one in focus, as I expected that I would... either it was only the kid or only the dog that was sharply in focus.
I am thinking that to fix this I need to make my aperture narrower. However to do so, I need to decrease my shutter speed which is often not an option with the outdoor lighting or bump the ISO which increases the noise. I have ordered an external flash will allow me to be able to use higher shutter speeds and also narrower apertures, and still have good exposure. Please correct me if I am incorrect in anything I am saying or if you have tips for me on how to solve this issue.
