Aperture

Aperture

Aperture refers to the size of the hole that lets in light through the lens when taking a picture or filming. The smaller the hole, the less light is let in. Each aperture setting has an 'F number' which refers to the amount of light being let in. Aperture also controls the depth of field which is the amount of sharpness behind and in front of the subject focus. The smaller the aperture the less sharpness in front and behind the subject focus. A larger aperture gives a greater amount of sharpness. Aperture is important for producing clarity and sharpness in film, it helps to enhance the focal point and emphasise certain aspects of a shot.

As shown in the video we produced we used different lenses to display how they effect the aperture and what the effect is on the film. We began with a standard lens with the F number at F8. The image is clear and everything in the frame is in focus. I have also imbedded a video that explains how the various F numbers affect an image or film. I feel that aperture is one of the more difficult camera techniques to explain and so this video helped me more clearly understand how to achieve the correct aperture and what it can be used for.
