A digital camera (or digicam) is a camera that takes video or still photographs, or both, digitally by recording images via an electronic image sensor.
Many compact digital still cameras can record sound and moving video as well as still photographs. Most 21st century cameras are digital.
Digital cameras can do things film cameras cannot: displaying images on a screen immediately after they are recorded, storing thousands of images on a single small memory device, recording video with sound, and deleting images to free storage space. Some can crop pictures and perform other elementary image editing. The optical system works the same as in film cameras, typically using a lens with a variable diaphragm to focus light onto an image pickup device. The diaphragm and shutter admit the correct amount of light to the imager, just as with film but the image pickup device is electronic rather than chemical.
Digital cameras are incorporated into many devices ranging from PDAs and mobile phones (called camera phones) to vehicles. The Hubble Space Telescope and other astronomical devices are essentially specialized digital cameras.
Once you’ve taken photos with your digital camera, you need to store them somewhere. You could always leave them on the memory card, but that would get rather expensive, so let’s explore a few other options.
1. Transfer your images onto your computer. Most cameras come with a wire to connect your camera to your computer, a CD with a downloading program and an instruction booklet. Transferring the images is fast and simple. Once they are on the computer, you can delete the images from your memory card and start taking more photos.
2. Burn your images onto a CD. If you have a CD burner on your computer, you can make photo discs to store or share with others. When it comes to pictures, it is often best to use a CD that can’t be written over. This will save the heartache of losing precious photos. Label the CD and store it where it can be gotten easily when you need to see your pictures.
3. Store your images on a public web site. There are many photo-hosting sites on the internet. Some charge for the service, but many are completely free. You have the choice to password-protect your images or share them with the world. This option helps if your computer should crash. Your pictures are safe.
4. Print your images and place them in a photo album. Many people still like turning the pages of a photo album and reviewing the memories. This also makes it possible for those without a computer to view your pictures.
5. Create a photo gift. There are places out there that will take your digital image and place in on shirts, mouse pads, cups, calendars and numerous other items. These make wonderful gifts and provide a way to keep a cherished picture near at all times.
These are just a few suggestions. Using your creativity, you will come up with many more ideas.
