The Techniques

Landscape Landscape is how you have the way of your camera in your hands. Landscape is that the width is wider then it is high. When you take a photo holding the camera straight, it will be captured in landscape mode. 

Portrait Portrait is how you have the way of your camera in your hands. Portrait is that the width is taller then the high when you take a photo holding the camera on its side will make the picture in to portrait.

Depth of field A camera can only focus its lens at a single point, but there will be an area that stretches in front of and behind this focus point that still appears sharp. Depth of field is where the camera will focus on one thing in the picture and makes the rest not that sharp as that one thing.

Shutter Speed Shutter speed is the length of time the film or digital sensor inside the camera is exposed to light, also when a camera's shutter is open when taking a photograph.  You need a fast shutter speed when a car goes passed.

Rules Of Third The Rule of Third is where You are breaking the image down into thirds (both horizontally and vertically) so that you have 9 parts on the picture. With this grid in mind the ‘rule of thirds’ now identifies four important parts of the image that you should consider placing points of interest in as you frame your image. Also with the Rule of Thirds you can use it to show where in the picture the main thing is and where your eyes go to.

Framing Framing is simply using other objects in your photograph to frame the main subject.

Aperture With Aperture when you don't need aa lot of light in your picture you have the lens less open and when its dark and you need more light in the picture the lens with open up, to get more light in.

Leading Lines Leading Lines is where the viewer's eye is attracted to lines that lead directly to the principle subject in the image. And where the lines leads to the vanishing point.
