Digital cameras are electronic versions of standard 35mm cameras that allow photographs and short video clips to be stored electronically on either internal memory, or removeable media such as secure digital cards.
Benefits of digital cameras include the ability to view + edit pictures on the camera itself, without waiting for the 35mm photos to be developed. Most cameras also include digital effects such as switching to black + white mode, panoramic mode, adjusting light levels, etc.
Most digital cameras connect to a computer system via firewire or USB, allowing quick + easy transfering of photos onto the home computer for further editing. Graphic software such as The GIMP and digikam allows easy photo editing, including the ability to create slide-shows of your photos.
Once photos are transfered and edited, special photo printers can be used to produce hard-copies of your photos in common 4"x6" or 5"x7" sizes, or many photo stores provide the ability to print digital photos professionally direct from cameras, removeable media or CD.

How to use with Linux
You must know that there are two types of digital cameras: One acts like a usb-storage when you connect the camera to the computer, and the other (PTP) needs a special, camera-specific software to get the images from the camera. Mostly, you can set your camera to act as PTP device or as mass storage.
PTP cameras
- Connect to your Linux Computer
- start gphoto2
gphoto2 --get-all-files
Mass storage cameras
dmesg
- In this example, we assume the device has been /dev/sda1
- Mount this device
mount /dev/sda1 /mnt/sda1
- Find your photos and movies on /mnt/sda1
