Yeah, I know - not a great photo, just two things I had on hand at the moment.

I was attempting to get the tractor in focus, with the little "house" blurred, but that is exactly the opposite of what I created.

Help please !

There are way to blur the background the way you want it to be, but as far as I know if you want to get the foreground in sharp focus you'll have to reshoot it. With a camera that have such a great DOF an easy way to get the focus where you want it is to compose your shot with the focus point (the tractor) in the middle of the LCD, push the sutther halfway down to have the camera do the focus, re-compose the image the way you want it to look like and then shoot. Hope this help!

Okay - I worded my question badly.

I don't want to fix that particular SHOT, I want to figure out how to fix what I did. So that I can take another shot which will look proper.

You need to control where your camera is focusing. If you can set the focus point do that - then you can focus where you want in the picture.

If you use the 9 point autofocus thing that most Canon cameras have you have no control over what area of the picture you are framing in the viewfinder the camera is going to focus upon.

To get the best blurred backgrounds, use aperture priority and use the largest aperture you have available to whatever zoom length you are using. Set your focus point and focus on the section of the picture you want to be in focus.

You need to lock your focus on the foreground object (most cameras do this be depressing the shutter half-way) and then recomposing the shot so the objects line up the way you want.

Much fancier cameras allow you to set the auto-focus point anywhere in the frame, but most use the center.

If you have manual focus, you can use that.

use "spot focus" and aim at the item that you wanna be in focus.

You can select any of the nine autofocus points with your Canon 20D. See pages 67-68 in the user manual.
