Digital photography is a great new way to capture, preserve, and share
your memories. Digital cameras work just like traditional film cameras,
but with a few key differences.
Like a film camera, they use a lens and a shutter. But instead of
recording the picture onto film, the images are captured with an
electronic image sensor that converts the image instantly to a digital
file, which is saved within the camera or onto a removable memory card.
A key feature of digital photography is that the image you shoot can be
viewed on a small screen on the back of the camera immediately, or on
your home computer/laptop at a later time.
With digital photography, one can do
more than take snapshots
for the family album. You can use your new digital camera to improve
your Photography skills over a short period of time.
You will be able to easily email digital pictures to anyone in the
world, or use them to populate Web pages and be able to upload to an
online photo album/gallery for friends and family to see.
You will be able to use programs, such as Adobe Photoshop to
create digital slide shows on recordable CDs/DVDs. Then you can add your
voice over narration, captions, music to finish the slide show and make
it look professional.
You will be able to transfer pictures
from your camera to your
computer with a USB cable, a card reader, or a docking
station. The fastest way to transfer pictures is by using a
card reader. Card readers come in many forms, they are
cheap, and they do not drain your camera battery which happens
when you link your camera up directly to a computer.
How dose it work?
Digital cameras record pictures using an image sensor array; a grid
composed of millions of Light-sensitive pixels. The pixels are the
building blocks of all digital images. A red, green, or blue filter
covers each pixel on the sensor so that it responds to only one of the
primary colours of light. Each pixel reads the brightness and colour in
a scene to produce an electrical signal. The signal is then converted
into a digital number that represents the colour and brightness of the
pixel spot in the image area. The camera’s built-in computer processes
the information to build a final image before storing it in the camera
memory.
Finally, your photographs can then be
printed at home, at retail outlet in your high street, or through one of
the online photofinishing service, such as Bonusprint, Truprint, Jessops,
Kodakgallery, Photobox, Snapfish, Tesco, bootsphoto etc..
if
you would like a quality professional photographic lab finish to your
images you can send them to 'digitalab' where you will find the extra cost well worth the end result.
