BSA 234 Cinematography - Week 1 & 2

During this two weeks, we went through the exposure triangle and talked about 3 in 1 shot.

The Exposure Triangle


Aperture (iris) controls the amount of light transmitted through to the sensor of the camera. This is controlled by F stop numbers on the aperture ring. It determines the amount of light enters the camera. The difference between each stop either doubles or halves the light entering the lens.



The shutter of the camera determines the amount of time the image is exposed for. If the image is too bright, it is "over exposed" whereas if the image is too dark, it is "under exposed". Another term for evenly spread of colour and tone in an image can be called "Appropriately exposed".

The ISO (Gain) also formerly known as ASA (American Standards Association) is the sensitivity of the film speed of a camera. ISO's can range from 50 (slow) to 1600 (fast).

3 in 1 Shot
We did an in class exercise filming a moving car traveling down the street. We filmed a shot of the car traveling towards the camera, a face on shot of the car travelling from left to right, and a shot looking at the car as it drives away. This is done by using the zoom and pan to capture different angled and sized shots.
