UNIT 1- EXPOSURE

In this blog I will talk about Exposure lighting in movies.

Exposure in lighting and exposure in cinematography, refers to the amount of light being captures by the camera. It is one of the most basic photographic principles, exposure is directly connected to the brightness and darkness of the image.

According to multiple resources an image can represent the normal exposure when it is similar to what the eye sees. With Overexposure happens when too much light is reflected into the camera, rendering an image that is brighter than normal exposure. Underexposure is the absolute opposite: Not much light enters the camera, thus creating a dark image.

Here are some images with that represent strong lighting exposure in movies.

  • Aperture

Aperture in lighting and movies is the opening in the camera lens has the capability to block or admit light. The word Aperture means opening. In the world of cinematography, this opening is located in the camera, more specifically on the lens. The size of the aperture is regulated by the lens ‘ diaphragm, which opens to admit light and closes to block it. The figure to the right shows the diaphragm, which is formed by several blades that leave a circular hole in the center which is known as the aperture.

When the camera turns into Auto mode ( According to sources ) the diaphragm achieves a certain level of autonomy also known as self control and behaves according to the camera’s sensors, which determines the amount of light entering the lenses.

  • Diaphragm

A Diaphragm is a thin opaque structure with an opening at it’s core. The main mission of the diaphragm is to stop the passage of the light except for the light passing right through the aperture.

  • ISO

Iso aka International Organization for Standardization originated from Greek ”ISOS”which means Equal. It is a very important global organization despite the fact in is non governmental.

In images ISO, it is the image of an entire CD or DVD, the contents of which can be completely duplicate and contain in a single ISO file.

  • Shutter speed.

In Photography, Shutter speed or exposure time is the length of time when the film or even it’s sensor inside the camera is to be exposed to a light. It is also when a camera’s shutter is opening when taking a photograph. In the amount of light that reaches the film or image sensors it’s proportional to the exposure time.

Shutter speed is the other side of the magic happens. It is responsible for creating dramatic effects by either freezing action or blurring motion.
