Question

describe the old camera and today's camera??​

Answer 1

Answer:

Everything has changed between cameras since the previous years.

The first camera obscura used a pinhole in a tent to project an image from outside the tent into the darkened area. It was not until the 17th century that the camera obscura became small enough to be portable. Basic lenses to focus the light were also introduced around this time.

At their most basic, cameras are sealed boxes (the camera body) with a small hole (the aperture) that allows light in to capture an image on a light-sensitive surface (usually photographic film or a digital sensor). Cameras have various mechanisms to control how the light falls onto the light-sensitive surface.

Answer 2

Answer:

old camera

Before the advent, and then explosion, of the digital camera, old cameras had to use film to record an image. The camera manipulated the properties of light to create an image on a piece of film, called a negative. Then, the negative went through a chemical process to create the end picture.

today's camera

A camera lens takes all the light rays bouncing around and uses glass to redirect them to a single point, creating a sharp image. ... When all of those light rays meet back together on a digital camera sensor or a piece of film, they create a sharp image.
