DIFFERENT TYPES OF PHOTOGRAPHY
There's a list of different types of photography in the url above. I will just name 10.
Advertising Photography

Astronomical Photography
Baby Photography
Black and White Photography
Cityscape Photography
Documentary photography
Family photography
Fine art photography
Food photography

Nature photography

EQUIPMENTS

Camera Bodies
it is important to have at least 2 cameras with you at all times. this enables you to be ready to capture anything at any time.

Lenses
the lenses you choose depends on the type of photography you are offering.Have a variety to use in many circumstances.

Flash Cards
Having a variety of flash cards handy is a must.If you have an error in your card , you’re better off using a variety of cards for different portions of your shoot than having one with a large capacity.
Flash units and Lighting Options
you will need to have at least one on-camera flash unit, and at least one stand alone flash unit for a more controlled light source.
Accessories
Depending on the type of shooting you are doing, you may need additional items to help you perform.

Cases and Storage
Storage cases are very important, especially for the photographer that shoots on location.They will protect your films

APERTURE


What Is Aperture?
The main function of a camera lens is to collect light. The aperture of a lens is the diameter of the lens opening and is usually controlled by an iris. The larger the diameter of the aperture, the more light reaches the film / image sensor. Aperture size is usually calibrated in f-numbers or f-stops. i.e. those little numbers engraved on the lens barrel like f22 (f/22),16 (f/16), f/11, f/8.0, f/5.6, f/4.0, f/2.8, f/2.0, f/1.8 etc. Each of this value represents one time the amount of light either more or less in quantity. i.e f/16 will let in 1X the amount of light than a diaphragm opening of f/22 .an aperture of f/4.0 will let in 1X lesser than that of f/2.8 



FOCUS
There are various methods to focusing depending on the type of subject being photographed. With portrait and animal photography, whether it is man or beast, the most important part of the image to capture sharply is the eyes.
SHUTTER SPEED

What is shutter speed ?
shutter speed is ‘the amount of time that the shutter is open’.
Shutter speed is measured in seconds – or in most cases fractions of seconds. The bigger the denominator the faster the speed (ie 1/1000 is much faster than 1/30).


ISO SPEED


Whether you shoot with film or use a digital camera, your choice of ISO has a direct impact on the combination of apertures and shutter speeds you can use.The job of ISO is to gather the light that comes through the lens and make an image. 
i.e If my camera is set for ISO 100, I have, in effect, 100 worker bees; and if your camera is set for ISO 200, you have 200 worker bees.If both of us set our lenses at the same aperture of f/5.6—meaning that the same volume of light will be coming through our lenses—who will record the image the quickest, you or me? You will, since you have twice as many worker bees at ISO 200 than I do at ISO 100.
METERING

Metering is a process which involves the camera taking a light level reading from the scene and selecting the appropriate combination of aperture and shutter speed to set the required exposure value. There are various types of metering which can be set, and these change the way the light levels are read by the camera.
Centre-weighted
a metering is taken from the whole of the scene first, then the central spot. The result is the average reading, but with extra weight given to the central part.
Zone metering
a type of metering which takes readings from several different areas - or zones - within the scene to produce a calculated average.
Spot metering
Spot metering takes a reading from a very small part of the image (between 1 and 5 per cent), and ignores the exposure of the rest of the scene.
WHITE BALANCE

White balance (WB) is the process of removing unrealistic color casts, so that objects which appear white in person are rendered white in your photo the reason we adjust white balance is to get the colors in your images as accurate as possible.

COMPOSITIONS


Point of Interest
When you've determined which area is the most important to you, you can compose to emphasize it.

Simplicity
it is important to keep your picture with just a few main subjects if there are numerous objects cluttering up the background, your message will be lost.

Contrast
A light subject will have more impact if placed against a dark background and vice versa. 
                                          
Balance
placing the main subject off-center and balancing the "weight" with other objects (smaller or lower impact) will be more effective than placing the subject in the center.b

Framing
A "frame" in a photograph is something in the foreground that leads you into the picture or gives you a sense of where the viewer is. For example, a branch and some leaves framing a shot of rolling hills and a valley, or the edge of an imposing rock face leading into a shot of a canyon.
Viewpoint
You can often change a picture dramatically by moving the camera up or down or, stepping to one side. One of the best ways to come up with a prize-winning photograph is to find an "unusual" point of view.

Direction of movement
When the subject is capable of movement,it is best to leave space in front of the subject so it appears to be moving into the photograph


Diagonals
Linear elements such as roads, waterways, and fences placed diagonally are generally perceived as more dynamic than horizontals.


Rule of Thirds
The exact center of any composition is not a satisfying place for the viewer's eye to come to rest. With the main subject placed in the center, the viewer is less likely to explore the rest of the photograph.

TECHNIQUES


There are many techniques stated in the url above. I'm just going to name a few here.

Panning
Taking a picture properly while moving the camera so it tracks with the subject's movement
Two things to keep in mind are temperature and light
There are some strange and unusual ways of approaching photography and its many uses.
