A contact sheet is a sheet that contains all the photos from a shoot in a grid format, this is used so that we can easily see which images are in in focus and have a good composition, etc. This makes it easier to pick out which are our best images. There are a few ways to make contact sheets, but when dealing with a large number of photos one of the best methods is to use Photoshop. By doing this it makes it easier to select which images are the best to then go on and edit.

White balance is when you change the settings on your camera make an object that appears white in real life to also appear white on camera depending in the lighting of your setting. White balance can be used under all different lightnings when things don't appear as they do in real life, for example in fluorescent, incandescent or shaded light.  White balance can also be used as an artistic effect to change the colours of objects, for example a white piece of paper can be turned blue or yellow.
