Flash
The function of the flash is mainly to get a clearer picture of what you are taking a picture of so its not iin total darkness, or to illiminate red eye.
Tripod
Having a tripod is like putting stabalizers ona bike, Ther for support for a more smooth ride, so in the case of a digital camera it is there to allow you to achieve better composition, allow you to better quality pictures and can have a slower shutter speed.
Aperture
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 image sensor. The aperture is usually shown in numbers of way; Maximum Aperture, which shows the maximum aperture for the lens, Aperture Range, which tells you the the maximum and minimum aperture and Maximum Wide-Angle and Telephoto Apertures, which gives the maximum aperture wide-angle and telephotu focal lenghs of a zoom lens.
Shutter Speed
Shutter speed is the length of time that your image sensor ’sees’ the scene you’re attempting to capture. Shutter speed is measured in seconds. If you speed up the shutter speed you’ll need to increase Aperture or make the ISO faster to compensate for it.
Focus points
The focal point of a lens is the point where all light reflected from an object is in focus.
Focal Length
is a measure that indicates the angle of view of a particular combination of a camera lens and film or sensor size.
ISO
ISO is the abbreviation for the International Organization of Standardization, The letters ISO on your digital camera settings refer to the film speed. The most common ISO settings are: 100, 200, 400 and 800. But on some digital cameras the ISO may also be 64, 100, 160, 200, 400, 640, 800, 1600.
Digital Manipulation
Cropping refers to the removal of the outer parts of an image to improve framing. Digital manipulation gives you the potential to create an illusion or deception.
