Revision: Exposure and Revision 2

1. Extreme close-up (shallow depth of field)
To achieve a shallow depth of field you need to push the f-stop down, which opens up the shutter. When shooting with a low aperture, the shutter speed will need to be quicker and the ISO needs to be lower to compensate for the extra amount of light being put into the camera for the wide aperture.

2. Mid/ Long shot: (greater depth of field)
In this photo you need to push up the f-stops (aperture) in order to make the shutter narrower and achieve a greater depth of field. With the narrower aperture, there will be less light coming into the camera therefore you will need to push up the ISO and slow down the shutter speed to compensate.

3. Freeze motion (fast shutter speed)
When shooting a moving object a faster shutter speed will freeze motion in the exact position when the shutter was clicked. Because the shutter speed is faster, there will be less light coming into the camera and therefore you will need a higher ISO and a wider aperture.

4. Blurred motion (slow shutter speed)
When shooting a moving object a slow shutter speed will blur the motion, as the thing that has moved across the frame is quicker than the shutter closes. When using a slow shutter speed, there is a large amount of light coming into the camera, so therefore you will need to lower the ISO and narrow the aperture.

5. Rule of Thirds
The rule of thirds is where two horizontal and two vertical imaginary lines are drawn across the scene. The idea is that the main lines or points in the image are meant to be across the lines or at one of the line's meeting points. The horizon is often thought to have to be drawn along the top horizontal line.

6. Leading lines:
The idea of leading lines is that the natural lines in an image should be composed so that they lead our eyes from the corners of the image into a larger or more significant focal point, or subject.

1. The relationship between aperture and shutter speed is that when one is changed, the other needs to also be dialled down or up in order to compensate for the extra amount of light or the decreased amount of light so as to correctly expose the photo.

2. Depth of field is how far into an image is focused; if the depth of field is shallow then only the foreground is focused, if there is a large depth of field then more of the image will be focused.

3. The most important setting on a camera when shooting moving objects is shutter speed, as changing that achieves motion blur or motion freeze.
