Depth of Field (DOF) Explained (The simple explanation)
| This is about how much blur there is, and how changing the aperture can change how deep the blur is. F5.6 (or less) is quite shallow, and so most of the fore and back grounds are blurred out; F22 and above has more of the picture in focus. Click on these below and see what I mean. Also notice that F5.6 lets in lots of light, and F22 lets in much less. Also see Depth of Field. |
