A camera is an optical instrument that captures a visual image. At a basic level, cameras are sealed boxes (the camera body) with a small hole (the aperture) that allows light through to capture an image on a light-sensitive surface (usually photographic film or a digital sensor).

How does a camera work physics?
Cameras use convex lens to take real inverted images. This is because light rays always travels in a straight line, until a light ray hits a medium.The glass causes the light rays to refract (or bend) this causes them to form inverted on the opposite side of the medium.

What is a normal camera called?
DSLR (or digital single lens reflex) cameras take photos to the next level of image quality.There are two types of DSLRs: the full-frame or 35mm, and the crop sensor or APS-C. A full-frame DSLR camera has a 36x24mm sensor, which typically yields better image quality and low-light capability.
Why did nobody smile in old photos?
One common explanation for the lack of smiles in old photos is that long exposure times the time a camera needs to take a picture made it important for the subject of a picture to stay as still as possible. That way, the picture wouldn’t look blurry.Yet smiles were still uncommon in the early part of the century.
Who invented the camera and why?

How does a camera focus?
To allow your image to be sharp, or to allow you to intentionally not focus, the camera and lens work together to change the distance of the lens from the sensor or film in order to control where the captured light converges. When the light converges precisely at the plane of the film or sensor, the image is in focus.
How is the camera like an eye?
The eye can be compared to a camera. The cornea is the transparent, curved front layer of the eye. The pupil, behind the cornea, is a hole in the colored membrane called the iris. Tiny muscles in the iris change the size of the pupil like the aperture of a camera to control the amount of light getting into the eye.
