. A point-and-shoot camera is sometimes called a fixed-lens camera because it cannot swap lenses.
What is image capturing in photography?
image capture (image acquisition)
The process of obtaining a digital image from a vision sensor
, such as a camera. Usually this entails a hardware interface known as a frame grabber, which captures single frames of video, converts the analogue values to digital, and feeds the result into the computer memory.
On which device does a digital camera store information?
A digital camera is a hardware device that takes photographs and stores the image as data
on a memory card

How do photographs work?
A photograph is an image made by a photo-chemical reaction which
records the impression of light on a surface coated with silver atoms
. The reaction is possible due to the light-sensitive properties of silver halide crystals. … Photography utilizes this chemical principle to record color and black and white images.
What is digital photography How is a digital photograph created How has digital photography change the art of photography?
How has digital photography changed the art of photography? Digital photography is a process in which there is no film yet

How does a digital camera work simple explanation?
A
digital camera takes light and focuses it via the lens onto a sensor made out of silicon
. It is made up of a grid of tiny photosites that are sensitive to light. Each photosite is usually called a pixel, a contraction of “picture element”. There are millions of these individual pixels in the sensor of a DSLR camera.
Why is the digital camera important?
