Camera Exposure

Camera exposure is the amount of light your film is exposed to. If the exposure is too high then the image appears bright but if the exposure is too low then the image will be dark.

This is an overexposed photo, as you can see, too much light has entered the lens and the photo is too bright.
This is an underexposed photo, not enough light has been allowed into the lens and the image appears dark.

Camera exposure is affected by three different things:

  • ISO
  • Shutter Speed
  • Aperture

ISO

ISO is the sensitivity of the lens to the light. If the ISO is set too high then the image starts to appear grainy and the noise is visible. A lower ISO means less image noise but if the ISO is set too low then the image will appear too dark but having the ISO as low as possible is usually preferred. You can use a higher ISO in combination with a very fast shutter speed and that will allow you to take photos without motion blur which is useful for things such as sport photography where you want to catch the action without motion blur.

The images above show the difference between having a lower ISO and a higher ISO. As you can see, a higher ISO makes the image appear ‘grainy’.

Shutter Speed

Shutter speed is how long the shutter stays open to allow light in to the lens. A lower shutter speed allows more light in to the lens but if the camera is not on a tripod then a slow shutter speed is bad because the image will be affected by camera shake or motion blur. Although if the camera is on a tripod then having a slow shutter speed can have some nice effects.

The images below are taken using a slower shutter speed.

A faster shutter speed is good for sport photography. If a slower shutter speed was used then the player would look blurry but having a fast shutter speed will take away that blur.

Aperture

Aperture is the ‘opening in the lens’. The aperture opens to allow light in to the lens. Aperture is measured in f-stops and the higher the f-stop, the smaller the hole. Aperture affects the depth of field of the image. A larger aperture means that the depth of field is greater and more of the image is in focus. A smaller aperture means that things at a closer distance is in focus while the background is blurred. Having a lower depth of field is good if the photographer wants people to focus on a certain point of the image.

This image was taken with a high aperture. The stacked rocks are in focus whereas the background is blurred and out of focus. A low depth of field is good if a photographer wants the viewer to focus on a certain point.

The Exposure Triangle

The exposure triangle is a reference that photographers use to balance the exposure when taking images. If you change one of the settings then you have to alter the other settings to get the correct exposure.

Composition

Rules of Composition

Rule of Thirds

The ‘Rule of Thirds’ is where you separate the frame into thirds making 9 equal sections. Photographers set up their shots based on these guidelines. When this rule is used, the main focus of the image is set up along these lines or on the intersections.

Symmetry and Pattern

Symmetry is where a line can be placed through the image and either side of that line are the same or very similar. Symmetry can be found through natural and man-made objects. Symmetry brings balance and proportion to an image.

Viewpoint

Viewpoints are the angle and position where the photograph was taken. A lower angle looking up can add a sense of superiority if it is an image of a person. A high viewpoint adds a sense of distance to the image.

Leading Lines

Leading lines leads the viewer towards a specific point of the image that the photographer wants them to focus on. Leading lines acts as a path for the viewers eyes to follow. Leading lines makes it so wherever the viewer looks, they will always end up on to the focus point by following the lines.

Framing

Framing draws attention towards a certain element by blocking out other parts of the image using the scenery. Framing adds depth to an image and the photographer can make the viewer focus on a specific point.

'My Name' Project

We were tasked to find different objects in the shape of letters of our name.

Lighting

To help us get a better understanding of how important lighting is and how different angles can give different effects we were given an egg, paper and a lamp. We had to place the lamp at different angles and take images of the egg.

Easter Project

Over the Easter holidays, we were set with the task to go out and take different images based on a theme. The three themes to choose from were Movement, Night or Form, Texture and Pattern. I chose to go with the night theme.
