camera is an optical instrument used to record images. At their most basic, cameras are sealed boxes (the camera body) with a small hole (the aperture) that allow 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. Lenses focus the light entering the camera, the size of the aperture can be widened or narrowed to let more or less light into the camera, and a shutter mechanism determines the amount of time the photo-sensitive surface is exposed to the light.

World’s 1st Camera :

Who invented the first camera :

Johann Zahn

How did the first camera work :

The first camera was essentially a room with a small hole on one side wall. Light would pass through that hole, and since it’s reflected in straight lines, the image would be projected on the opposite wall, upside down.

A camera is an optical instrument used to record pictures. At their generally fundamental, cameras are
fixed boxes (the camera body) with a little opening (the gap) that permit light in to catch a picture on a
light-delicate surface (typically photographic film or an advanced sensor). Cameras have different systems to control how the light falls onto the light-touchy surface.

Digital camera :

A computerized camera or digicam is a camera that catches photos in advanced memory. Most cameras
created today are advanced, and keeping in mind that there are despite everything devoted.
Quality committed cameras are still regularly utilized by experts and the individuals who want to take
better photos.

Professional video camera :

An expert camcorder (frequently called a TV camera despite the fact that its utilization has spread past
TV) is a very good quality gadget for making electronic moving pictures (rather than a film camera, that
previous recorded the pictures on film). Initially produced for use in TV studios, they are currently
likewise utilized for music recordings, direct-to-video films, corporate and instructive recordings,
marriage recordings, among different employments. Since the 2010’s, most expert camcorders.

Owner & Founder at Johann Zahn designed the first camera in 1685. But the first photograph was clicked by Joseph Nicephore Niepce in the year 1814. It was thousands of years back that an Iraqi scientist Ibn- al- Haytham made a mention of this kind of a device in his book, Book of Optics in 1021.
