“Since the advent of the consumer digital camera, hard
disks and memory devices have faced the burden of ever increasing
amounts of images to store. This is, in part, due to digital
photography being an inexpensive way of taking thousands of images
without any image processing costs to bear, thereby encouraging the
photographer to snap many pictures of the same thing. The only
ongoing expense is recharging the batteries in the camera.“When a digital camera captures an image, its image sensors
records the light from millions of sensing area. The camera’s
digital circuitry converts the generated analog voltage signal into
a digital representation. Many cameras allow these images to be
stored in a raw image file. They are akin to digital negatives, as
they have the same role as negatives in film photography. These RAW
files usually offer higher color depth than JPEG files, but take up
far more storage space.“Linux offers excellent software for dealing with RAW files, for
remotely operating cameras, importing and processing raw data, as
well as software to read, write and edit camera metadata.”
