Cameras are devices
used to take photographs or motion pictures usually using either
film or digital media.
The camera works by reproducing the light image of objects on film,
or converting those images into digital image files. Most consumers
these days use digital cameras both for taking photographs, and for
making movies or videos. However, professional photographers and
cinematographers often still prefer to use film.
The advent of digital technology allowed cameras to become
progressively smaller and more portable. Digital cameras are
equipped with disk storage that allows the photographer to tak more
pictures compared to what is practically possible with film cameras.
As you can erase old pictures off of the camera storage after you
upload them to your computer or other device, the disk is reusable.
So the costs of buying film as found with older camera types is
eliminated with the digital camera. However, the digital camera
generally requires at least a computer or photo printer for
practical use, so that must be considered a required additional
expense. Although you could simply have digital pictures printed at
photo shops, most users prefer to store the images on other devices.
Another advantage of digital cameras is that they allow the
photographer to adjust images optically using digital techniques
that previously required expensive camera lenses.
Despite the expense and inconvenience associated with film, many
photographers still use film cameras for a variety of purposes.
Digital cameras create a pixel view, which is different than that
produced by film. Large format film offers a higher spatial
resolution as compared to pixel resolution available with digital
cameras. For cinema in which the imagery if very important, motion
picture directors often choose film for their cinematography.
Although one can achieve a higher quality product with film, this
usually requires a lot more work than with digital cameras. Not only
is there far less automated features available with film, but the
processing of the film is also important in achieving an optimum
result. For professionals, these extra steps and costs are no
problem and sometimes essential, but for the average consumer,
digital photography is more than sufficient for their needs.
