I had my subject with a microphone in his hand. I took one photo at a lower Aperture, F Stop, in this case f 4.5. At this aperture setting notice how the microphone is in focus but nothing else is. When I changed the aperture to a higher aperture number, in this case, f 10.0 notice how so much more of him is in focus than before.
I had the camera in the AV mode to be able to adjust the aperture.
I also had to change the other settings in photoshop, because the amount of light coming into the camera also changed.
