That's probably my biggest problem. I want to blur out what's behind, but I don't need it so shallow that the nose is out of focus, huh?
Then just use a smaller aperture (higher f in your settings). This will allow you to use a bigger DOF. But you will have to compensate a bit with a slower shutter speed or, if you can not afford that, a higher ISO. Otherwise, as you are letting less light to hit the sensor, your picture will be darker. Aperture priority mode is the best way to have a control of your DOF.
