In a film camera, the lenses serve to focus the light from a scene onto film treated with chemicals that have a controlled reaction to light.The lens in a camcorder also serves to focus light, but instead of focusing it onto film, it shines the light onto a small semiconductor image sensor.

What is a video camera and how it works?
The electronic or VIDEO CAMERA is similar to any other camera in that light reflected from an image is focused by a lens onto a plane inside the camera. Unlike the film camera, the video camera contains a CAMERA TUBE which processes the image.
How a camera works step by step?
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.
How do film video cameras work?
A motion-picture camera essentially consists of a body, a film-transport system, lenses, shutter, and a viewing-focusing system.A mechanical claw pulls the film into position behind the shutter, locking the film momentarily in place. The shutter opens, exposes an image onto the film, and closes.
How is a video recorded?
Video recording is the process by which visual images are recorded on some form of magnetic recording device such as tape or a video disc.When a camera is focused on a scene, the visual images it receives are converted to an electrical signal within the camera. That electrical signal passes into the recording head.
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 do point and shoot cameras work?
A film or digital camera in which the focus and exposure is entirely automatic. The user aims the camera and presses the button; the camera does the rest. Point-and-shoot cameras can range from cheap throw-aways to pocket-sized digitals.
How does a mobile camera work?
When taking photos of an object, your camera phone will capture the light coming from it. A convex lens is used in the camera to focus incoming light onto a CMOS sensor.The lens focuses incoming light onto the sensor in the camera. The sensor then creates a digital photograph from the incoming light.
Do film cameras need batteries?
Very simple film cameras don’t need batteries, but most do use a battery to work the exposure meter. Sophisticated ones may have a battery to wind the film, and for autofocus, flash, and other automation.

What is ISO camera?
ISO Control
For digital photography, ISO refers to the sensitivity—the signal gain—of the camera’s sensor. The ISO setting is one of three elements used to control exposure; the other two are f/stop and shutter speed.The solution for both instances: boost the ISO to increase the sensor’s sensitivity to light.
How does focus work in the brain?
Your brain directs focus capability by filtering important information and moving it up the ladder for deeper processing while suppressing interruptions from irrelevant bits and pieces — a function known as efficient selection.
Which is better point-and-shoot or DSLR?
A DSLR always gives better quality of pictures than a point-and-shoot. The difference is evident while shooting in low light; with proper lenses and settings, a DSLR delivers superior results.Most DSLRs have a battery life of over 500 shots on a single charge. The point-and-shoot cameras usually allow 200 shots.
Can film cameras zoom?

How does a 3D camera work?
A 3D camera is an imaging device that allows the perception of depth in images to replicate three dimensions as experienced through human binocular vision. Some 3D cameras use two or more lenses to record multiple points of view, while others use a single lens that shifts its position.
