[QUOTE="Eyelight, post: 348757, member: 24753"] I use Photo Caddie on the phone. Another good site on DOF is dofmaster.com You can use a smaller aperture or move back a few inches (or centimeters). Guessing you were about 20 inches away, which gives a DOF of .55 inches. Changing to f/4 would more than double the DOF to 1.24 inches. Keeping the fast aperture of f/1.8 and moving back 10 inches increases the DOF to 1.27 inches. The near depth of field or the portion between the focus point and the camera, at f/1.8 and 20 inches would be 0.27 inches, so that slight turn of the head was just enough to move the eye on the right into the soft blur. It's still a very good shot though. Captures that something that the little ones have. [/QUOTE]
