Digital cameras allow you to make photographs and short video clips to be stored electronically on either internal memory, or removable media such as SD cards.
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.
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.
Get the pictures
You can take the memory card out of your camera and read it using a USB card reader. If you do not want that, it depends on your camera type what you can do to get the pictures.
- Connect to your Linux computer
- start gphoto2
Mass storage cameras
- 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
Manage your photos
You have more pictures than your camera can store. You want to have all pictures in one folder and when you delete a picture on the camera or in the folder, you want an information and a possibility to propagate these changes. You want to manage your photos.
tweedleburg:~ # hwinfo --block --short disk: /dev/sda SAMSUNG HD103UJ /dev/sdb WDC WD3200AAKS-7 /dev/sdc Generic USB SD Reader /dev/sdd Generic USB CF Reader /dev/sde Generic USB SM Reader /dev/sdf Generic USB MS Reader partition: /dev/sda1 Partition /dev/sdb1 Partition /dev/sdb2 Partition /dev/sdc1 Partition cdrom: /dev/sr0 HL-DT-ST DVD-ROM GDRH20N /dev/sr1 TSSTcorp DVD+-RW TS-H653B
In this case, the block device is /dev/sdc and the partitiOn is /dev/sdc1. Mount it:
And synchronize it with the cam-folder. If necessary, create it:
mkdir cam unison /mnt/sdc1 cam
Now the program unison presents me a nice overview which files (pictures) have been added, deleted and modified in which folder. I can decide if I want to copy files and in which direction.
Choosing a digital camera
- does it have a menu structure that you understand?
- what resolution has it (MegaPixel)?
- can you use SD cards (many computers have slots for them)?
- is it capable to use SDHC cards?
- can you charge it using a standard adapter (micro USB)?
