Apertures

The aperture is the hole behind the shutter that allows light into the camera. The F stop on the camera is what is used to adjust the size of the hole. The smaller the number the bigger the hole.

The depth of field is the amount of the photo that is in focus. If a large F stop is used the image is small depth whereas if a small F stop is used, the image has a big depth.

F:3.5 is a small F stop meaning only the foregound is in focus.

F:9 is a medium F stop meaning the foreground and mid ground are in focus.

F:22 is a large F stop meaning the whole of the image is in focus.

If a higher F stop is used, less light goes into the camera due to the hole size, therefore meaning the shutter is open for longer. When using this F stop the camera needs to be still to ensure the image is in focus, using a tripod with allow this to be possible.

If a lower F stop is used more light is allowed into the camera as the hole is larger and therefore the shutter speed is increased.

High F stops are good in bright lighting conditions

          F22                                                                                                            F3.5

-High depth of field                                                                                    -Low depth of field

-Good for bright conditions                                                                -Good for dull light conditions

-Shutter needs to be open for longer                                                        -Lets more light in

-Allows less light in                                                                 -Shutter doesn't need to be open for too long

The first three images I used I small F stop approximately F:4.5. The use of these F stops meant my images were focused in the foreground and out of focus behind this.

The two final images I used a higher F stop approximately F:24 in order to make the whole of my image in focus.
