[QUOTE="WhiteLight, post: 147552, member: 9556"] DOF depends on a few factors, specially if you are not using a prime lens. First, you need to be as close as possible to the subject Second, the lens must be at the longest focal length - for the 18-55, best DOF can be achieved at 55mm Third, the background must be at least 6-8 feet behind the subject. Last & most importantly, you must at the lowest possible f number like 3.5 in the 18-55 or 1.8 in most prime lenses. Regarding the pic you posted, there is nothing wrong with it. Since you focused on the eyes, the nose is going to be blurred. Think of where the eyes are as a sheet of paper & keep placing more sheets till you reach the nose. Lots of sheets of paper in between eh? That shows each of them are in different focus planes, hence the blurry nose & clear eyes [/QUOTE]
