Photography: Mid term complete guide.

Photography

Photography

The process of capturing light through light-sensitive digital sensors or photography film.

Art and Science

Photography is considered both an art and a science, as it requires technical processes to capture and process light to create visual images.

Human Eye

The natural device through which we see the world and capture images.

Camera

An artificial device that performs similar functions to the human eye in capturing and preserving images.

Inverted Images

The human eye registers inverted images on the retina, while the camera does it on digital sensors or film.

2D and 3D Images

The camera captures 2D images, while the human eye captures 3D images.

Light Adjustment

Both the human eye and the camera adjust the quantity of light entering to make things visible.

Camera Settings

In the camera, we can manually adjust the aperture, shutter speed, and ISO to control the light, while the human eye adjusts the iris automatically.

Camera Resolution

The highest resolution of a camera is around 100 megapixels, while the human eye is estimated to have 576 megapixels resolution.

Camera Lens

The first part of the camera that collects and directs light into the camera.

Lens Types

Different types of lenses are chosen based on the subject and lighting conditions available.

Prime Lenses

Lenses with fixed focal length, making them faster and sharper.

Zoom Lenses

Lenses that use a series of lenses to allow different focal lengths, making them more flexible but not as fast.

Focal Length

The distance between the point of convergence of the lens and the sensor or film, which defines the amount of zoom.

Aperture

The diameter of the lens that determines the maximum amount of light that can pass through.

Depth of Field

Controlling the amount of the photo that is in focus to draw the viewer's eye where the photographer wants.

Shutter Speed

The mechanism that controls the amount of time light is let onto the film or sensor.

ISO

Artificial light that can be added to a photo to increase its brightness.

Viewfinder

Helps preview the picture before it is captured.

Sensor

Digital sensors composed of pixels that convert light into electricity.

Metering

How the camera determines the correct shutter speed and aperture based on the amount of light and ISO.

Meter Reading

The camera's measurement of the amount and intensity of light to determine the optimal exposure.

Caption Writing

The process of adding captions or descriptions to photographs.
