Shutter Speed

• Shutter speed is how much light is let into the camera shutter, if the camera shutter is left open for a long period of time the more light is let in, the shorter the shutter speed is open for the less light is let in. When the person taking the picture wants to get a clear action shot they would make sure the shutter speed is fast. When the shutter speed is left open for a long time the image becomes blurry and makes the things in the image distort and appear stretched out. When taking an image of light with the shutter speed open for a long time and you move the light around once the photo is taken it would become a beam of light also you can make shapes from a single light by moving it around whilst the picture is being taken.

Shutter Speed

Fast Shutter Speed (1/100) Slow Shutter Speed (1/6)

ISO

• The lower the ISO is it will produce a higher quality image but needs more light to make the image exposed. The higher the ISO is it will produce a lower quality image but has less light.So the higher the ISO is the brighter the image appears is becomes extremely white and you cant make out anything in the image, the lower the ISO is the darker the image will turn out. You have to change the cameras ISO in different places if outside in daylight you would need to lower the ISO, if you are indoors you would higher the ISO to let the enough light in to brighten the image. The lower the ISO, the less sensitive the camera is. In other words, a lower ISO will need more light to properly expose a picture than a higher ISO.

Aperture & Depth of Field

• The depth of field is what is in focus in an image a narrow depth of field means the thing closest to the camera would be in focus whilst everything in the background appears blurred, a wide depth of field means that the thing closest to the camera appears blurry whilst everything surrounding the image is in focus. The depth of field is a point in the picture that the camera focuses on and only focuses on that part making the rest of the image blurred, it changes in size and is described one being ‘narrow’ and the other being ‘wide’ depth of field. People use this if they want to have a main focus in a image, they want people to pay attention to the clear part of a photo. The subject in the photo would be in focus.

Rule of thirds• Rule of thirds is when the image is put into parts

by having a grid displayed on the screen this helps the person taking the photo get what they want where they want it in the photo, so if they want something centred in the image they would then make sure that the subject is in the centre square of the grid, making it the first thing someone looking at the photo would see.It makes the image divided into nine squares, this then acts as a guide to placing things in an image purposely to get the image framed. 2 horizontal lines and 2 vertical lines letting you positon the important things. Also it helps setting the photo up in away that more of the surrounding areas can be included in the image along with your main subject you can still place your main subject slightly off to one side giving you a chance to include more into the image.

Examples of Rule of thirds

Manual Exposure

• Manual exposure is a mode on the camera which you can set the shutter speed and aperture etc. using the camera settings and changing each one individually

ISO - 100Exposure time – 1/100F/5.6

Automatic Exposure

• The automatic exposure on a camera is the mode you set which will make the decisions for you including the aperture settings, shutter speed, white balance and ISO.

ISO – 100Exposure time – 1/800F/6.3
