The shutter speed is the amount of time in which the shutter opens and closes. The shutter speeds is measured in fractions of a second e.g. ¼, ⅕ or 1/30 of a second. The slower the shutter speed the more light will enter the camera, the quicker the shutter speed, less light enters the camera. You can change the shutter speed to a slower or faster speed depending on what you are going to take a photo of. you normally require faster shutter speeds when taking a picture of fastest action or certain sports sport in bright lighting. Slow shutter speed letting more light get into the picture, but has the potential risk of ‘camera shake’. Camera shake is when the shutter slow shutter speed records fractional movements of the camera making the image blurred, or as if the whole image is moving. Fast shutter speed captures fast-moving objects before it goes away.
Depth of field
The smaller the aperture (hole) or ‘f stop’ the greater the depth of field which means more of the picture is in focus. The depth of field is a measure shown on camera lenses of distances that will be in focus in front and behind the item you focus upon. The larger the aperture the shallower the depth of field. This means things in front or behind the subject will be out of focus. You can change the depth of field so you can get the background in focus plus the subject and the foreground out of focus.
We measure white balance in Kelvin which in other terms is known as the Kelvin scale. If there are two conflicting colours then that is called a colour cast which will appear in the picture . white balance is when you get un natural light mixed with natural light and disturbs the picture and makes the colour balance un even in the picture. you can create white balance if you put all of the primary colours with the scam amount of colour and brightness to create a white colour this is used in the camera flash. white balance is also telling the camera what is wight so the camera can function round the different colours.
