Digital Camera
A digital camera. Its genius speaks for itself. A device
that can capture a moment in time and save it forever is beyond revolutionary. The
modern camera evolved from the camera obsurca
that produced the first photographic image; however the image required several
hours of light exposure and faded with time. Later, the film camera, requiring
rolls of film, manual adjustment of aperture, shutter speed and film speed to
achieve a balanced exposure, and chemical development was created. Finally, we
arrived at the beloved, absolutely fascinating digital camera! The digital
camera is now a part of everyone’s daily life as it is incorporated into many
handheld devices including MP3 payers, PDA’s, laptops, phones and cars.
According to Wiki, “Digital and film cameras share an optical system, typically
using a lens with a variable diaphragm to focus light onto an image pickup
device. The diaphragm and shutter admit the correct amount of light to the
imager, just as with film, but the image pickup device is electronic rather
than chemical.” Along with electronic development, another awe-inspiring aspect
of the digital camera is its ability to immediately display every shot on a screen
for users to view, zoom in to, edit and delete from memory. You never have to
worry or wonder what your picture looks like or how it can be improved because
all relevant curiosities are satisfied with the click of a button.
The various forms of digital cameras make them suitable for
almost everyone including toddlers and the elderly. Compact cameras and phone
cameras were designed to be easy to use, sacrificing advanced features and
picture quality for simplicity and compactness; perfect for many who don’t intend
to display their images on a large scale and only engage in casual photography.
There are also several high end cameras perfect for professional photographers
of all sorts.
The camera fulfilled a human’s inability to memorize every
detail of a scene or multiple scenes. Rather than a painter needing their
subject to stay still for the duration of their process, they can now take a
photo to reference at their will. We can now record memories and a range of instances
we deem important including birth, weddings and crime scenes. Picture-producing
cameras also provide the ability to share an emotion, mood, sense,
and feeling that cannot be relayed in words.
The effectiveness (to say the least) of the camera is
readily evident literally everywhere. Whether you are in a building of any sort,
outside, or on the computer, you are guaranteed to see an abundance photos in
frames, on walls, clothing, billboards, incorporated in other design, and so
much more. Also, the overwhelming use of smartphone cameras has initiated the
creation of numerous apps and web-based services to facilitate easy and quick
photo manipulating and sharing. This evidence directly speaks for the success
of the camera on every level.
