One of the main features of an SLR camera (single lens reflex) which isn’t found on many point and shoot cameras is the ability to chose how fast the shutter opens and closes (shutter speed). The speed is measure incrementally in seconds. This camera allows you to go from the B setting (bulb) which is a long as you can keep your finger on the shutter release all the way up to a 1000th of a second.

Click on the dial to see examples of fast and slow shutter speeds

The particular camera we are using here is called a 35 mm SLR camera. This is because of the film used, which goes by the same name – 35mm (35mm representing the width of the film)

There are different types of film available, such as black and white and colour. Within both of these are also different speeds of films. Film speed refers to how fast an image can be captured, the faster the film the briefer the exposure has to be. However, very fast film can make images become grainy which has an effect on the overall quality of photographs.

The speed of a film is expressed in numbers on a rating devised by the International Standards Agency which ranges from approx ISO 50 – ISO 3200.

A good all round film which provides average exposure times and a good quality image is ISO 400.

Aperture refers to how much light is allowed into the camera and is operated on the lens. It is measure on a F scale and can range from F/1.7 to F/22. The more light let in, the lower the F number and vice versa

Using a faster shutter speed can enable you to freeze the frame and capture images that the human eye cannot see.

Fast shutter speeds are often used in sports photography where the environment is very action packed.

Page 12: SLR Camera (Single Lens Reflex)

Slow or longer shutter speeds allow more light into the camera. As a result of this any moving object becomes a blur.

A tripod is often required to keep the camera still as the slightest of movements would equate to the whole image becoming a blur.

Artists often use longer shutter speeds to give their work more meaning

Page 13: SLR Camera (Single Lens Reflex)

Using a low aperture creates a soft blurred background and a shallow depth of field, often used in portrait photography. A high aperture renders everything in focus creating a very deep depth of field which is an approach adopted by many landscape photographers.

Page 14: SLR Camera (Single Lens Reflex)

Another feature of the SLR camera is the capability to change the lens. There are many different types of lens, each radically changing how your images look. The main types of lens are : the wide-angle, macro, normal focal length, telephoto, and zoom lenses. They are usually named after their particular focal length e.g. 10mm (wide-angle), 50mm (normal focal length) or 135mm (telephoto). Zoom lenses combine different focal lengths and is named by its longest to shortest focal lengths e.g. 18 – 55mm.
