A contact sheet is a page in which a photographer presents all of their photos from a specific shoot. All photographs that are taken are included even if they are out of focused or over exposed. This process helps photographers narrow down their photos and find their best shots that they will develop further. There are a few ways to make contact sheets such as using a program called bridge. Firstly select all the images out of your file that you took on the shoot, then change the layout for example number of columns and rows. at this point you can make other adjustments such as removing text and changing the background colour. You can then save it as a JPEG back into your file and make notes and sketches on it to show improvements that could be made and pictures that need removing or editing.

The exposure triangle is a common way of associating the three variables that determine the exposure of a photograph, these are: aperture, shutter speed, and ISO. A person must balance all three of these to achieve a desired result as they have a significant impact on how your photos will look and feel. Aperture, affects the depth of field, or how much of an image appears sharp. Shutter speed also affects image sharpness, with slower shutter speeds leading to blurred images and faster shutter speeds resulting in sharper images. The choice of ISO enables you to use the optimum combination of aperture and shutter speed when the amount of light would normally prevent you from doing so. However, increasing the ISO also reduces the quality of your images.
