Hi David. I've removed your other post, as this is the forum you need to be in with regard to camera settings. However, you will see from my reply that it is not necessarily the camera you will have to change to get the result you want.

You can change the image size in your editing software. There will be a menu option that will open a diagogue that will allow this.

If you need any help with this it would help to know what software you have, and it may be you will get a better response if you post another question around this in the software forum.
