Camera
Camera
is a tool that is made for capturing image or recording certain moment. Camera
is made from three basic elements : an optical element (the lens), a chemical
element (the film) and a mechanical element (the camera body), by combining
those three elements in such a way, we can get an image and recording.
The word "camera" itself comes
from Latin camera obscura which means "dark chamber", an
instrument for projecting an object in real life onto a flat surface. Camera in
these days adopt the work of camera obscura. The object that is captured and
recorded can be save in the storage inside the camera, and it can be
transmitted to another location such as laptop, smartphone, and flashdisk. A camera
is powered by rechargeable battery. There are some different types of battery
that influence the price, size, and the performance of the camera itself.
The other components of camera are : The shutter release button and memory card stores. The
shutter release button is the mechanism that “releases” the shutter and
therefore enables the ability to capture the image. The length of time the
shutter is left open or “exposed” is determined by the shutter speed. The memory card stores all of the image
information, and they range in size and speed capacity. The main types of
memory cards available are CF and SD cards, and cameras vary on which type that
they require.
Now days, camera develop
from many side, such as in the capacity, which modern camera or we call it
digital camera can hold hundreds and sometimes thousands of photos on a single
media which is very different with the old camera which can just save some
pictures inside. And the other develop of camera is from the features or
effect, in modern camera there are some options such as portrait, panorama,
timer, night mode, and many more. But, in the old camera, those options disappear.
Camera in these days also include in other tool, such as laptop and smartphone.
