Aperture - The amount at which the lens opens to allow light in.
Large F-Stop = Large Depth of Field (generalised focus on the entirety of the image) = More Light Needed
Small F-Stop = Small Depth of Field (Focuses on a particular thing and blurs around the subject in focus)= Less Light Needed
Small F-Stop = Small Depth of Field (Focuses on a particular thing and blurs around the subject in focus)= Less Light Needed
Shutter Speed - The amount of time the shutter in the camera is open for. By having a quick shutter speed a clear photo can be taken - a quick shutter speed is ideal for action photography. When using a slow shutter speed to get for example long exposure photos it is best to use a tripod as the photograph will capture any movement creating blurs and distortion.
ISO Settings - ISO measures the sensitivity of the colour sensor. The lower ISO is the less sensitive the camera is to light and the finer the grain will be. The higher the ISO the more sensitive the camera is to light creating a light grainy photograph. So having a fairly low ISO will give good results.
Lens - A lens is used to alter the way light is entering the camera with pieces of curved glass creating a range of effects. Lenses can be used to make better photographs for example using a wide angle lens will allow the photographer to get some amazing landscape photographs because it allows for more the subject area to be processed
Composition - How the subjects are arranged in an image (Image content). Composition of a photo makes use of leading lines and rule of thirds making items in the image more predominate among the background or making subtle pointers towards a certain aspect of the photo.
