There are eleven possible direct paths between the
five main components of the digital photography process. From camera
to print, and taking in storage, almost all of these are direct and
can be achieved by the photographer.
This puts the photographer in control of the whole process, or gives
the choice of handing over any element. This degree of control and choice
is one of the main benefits and attractions of digital over chemical
photography.
1.CAMERA
The camera is obviously the key of the whole process. The camera can
hook up directly to a computer, even to a printer, but it is usually
more convenient to use a card reader as an interim storage medium.
2.STORAGE: short-term
The memory card is sometimes described as 'digital film' because it
is the medium on which the photograph is immediately stored. The card
can stay in the camera while the pictures are transferred but there
are many advantages in removing the card and using a card reader. The
first of these is that cameras are heavy on battery power and you will
be using this during transfer unless you go to the extra trouble of
plugging it into the mains.
A card reader plugs into your computer and your photographs are available
for viewing, editing, or transferring. Alternatively you can take the
card along to any up-to-date processor and have your photographs printed
directly from the card.
Many home printers these days will also print direct from the card.
3.STORAGE: long-term
The file which constitutes all of the information about a photograph
(more than just the image) is the digital equivalent of a negative.
Because it is digital data it will never degrade and will not reduce
in quality however often it is transferred. This of course does not
mean that the storage medium cannot degrade or that the file may become
corrupt if improperly transferred but there is a wide choice of media
and backups can be kept on moret han one.
The first medium is likely to be your hard disk on the computer but
this should never be relied upon for longer than processing time.
The most popular medium at the moment is the CD, which is rapidly being
overtaken by DVD.
4.PROCESSING
Processing used to mean the chemical development of a negative or transparency
and and the creation of a subsequent print. With digital it is quite
possible to go sttaight from camera to print, but let's assume that
the picture isn't perfect. Once it is on the computer there is a vast
array of software available to enable you to make simple corrections
or crops, or to transform your photograph completely.
5.PRINT
Finally, to print. Although many people still keep it simple and take
their snaps or masterpieces in to be printed, today's generation of
inkjet printers, combined with photographis quality inks and papers,
are capable of producing superb photographs at up to exhibition size
prints.
Printers will produce a picture direct from the card or computer, or
- via the computer - from a long-term storage medium.
There are also a number of online printshops which will accept your
photograph by email and post the finished prints to you.
If there is one quality which makes digital excel over chemical photography it is the element of choice. You can control the whole of the process, or any part, at any stage.
