White Balance and Focal Length

White Balance

White Balance is a setting on a SLR camera that helps to change the lighting to help so that white objects appear white in the photograph. Sometimes this is difficult to do because the light cast from different light sources is different colours. This is called colour temperature; an eye is very good at judging what is white beneath different light sources in contrast to an SLR camera, which has difficulty picking it up as auto white balance. For example, it can create a blue and orange colour cast. White balance helps you prevent picking up these colours when taking a photo and it also helps you take a better picture under different light conditions.

Focal Length

Focal Length is the distance light rays that come together to make the image sharp of an object to the digital sensor. Focal Length tells us the angle of the sight, like how much the camera has increased and how much the camera frame has captured. The more the focal length the narrow the view of the angle will be and the magnification will be greater. So the opposite will be the shorter the focal length the longer the angle and the magnification will be smaller.
