SO crazy and frustrating. But I'm happy to see strategies and whatnot factor into the race. Just terribly unlucky... but I'm more than willing to abide by the rules... so a drive through next race for me.
Depth of field is how much of the field is in focus. It is either shallow or deep (small or large) Shallow means only a small range is focused upon, the background and/or foreground is blurry. It could be that both the forground AND background are blurry.. either way, the DOF is very narrow, the rest is blurred:
A greater depth of field means most or all the image, despite being at different distances to the camera, are in focus.
Shallower DOFs make pictures much more interesting as the eye is more drawn to the focused part, making things pop quite a bit more.
You're welcome. Now continue with the deep/shallow jokes...
