Understanding Depth of Field
Photography is probably the worlds most common past time in the world. Every second there is a new picture taken somewhere on the planet. Some by amateurs and some taken by pure professionals. Within movies and photography there is something called “Depth of Field” and it’s basically and simply put the way the photo is taken from a focused point of view. While amateurs usually just take a picture which portraits the whole image in focus, a professional picks an object within the frame and focuses the photo around that object, leaving everything else out of focus.

What Is Tilt-Shift Photography?
Wikipedia “Tilt-shift photography” refers to the use of camera movements on small- and medium-format cameras, and sometimes specifically refers to the use of tilt for selective focus, often for simulating a miniature scene. Sometimes the term is used when the shallow depth of field is simulated with digital postprocessing; the name may derive from the tilt-shift lens normally required when the effect is produced optically.

What is Tilt shift photography
Tilt-shift photography refers to the use of camera movements on small- and medium-format cameras; it usually requires the use of special lenses.
"Tilt-shift" actually encompasses two different types of movements: rotation of the lens relative to the image plane, called tilt, and movement of the lens parallel to the image plane, called shift. Tilt is used to control the orientation of the plane of focus (PoF), and hence the part of an image that appears sharp; it makes use of the Scheimpflug principle. Shift is used to change the line of sight while avoiding the convergence of parallel lines, as when photographing tall buildings.
In many cases, "tilt-shift photography" refers to the use of tilt and a large aperture to achieve a very shallow depth of field. Know More

Nikon Autofocus Tutorial
This video explains into depth about Nikon's autofocusing system in Nikon's lenses and camera bodies - showing into depth about the settings to get your image crystal clear in focus. Enjoy.
On the second hand, sorry, we forgot there is a slight difference in the focus indicator (aka "electric rangefinder") on the lower end DSLR's. Okay, on the lower end DSLR's, there won't be any triangles at all - there is only green dot that alerts the user the subject in focus. Continue focusing manually by estimate until the green dot lights up continuously in the viewfinder. These models don't have both triangles happen to be: D40, D40X, D50, D60, D70, D70s, D80, D90, D100, D200, and D300.
