Digital Camera Basics


It’s nice to pick up a brand new camera and take good pictures without reading the manual. But the manual will always tell you something about your camera that you wouldn’t discover on your own. So give it at least one good read. And keep it handy .If you have any problems, consult the manual to see if it has the answers.

Purchasing a digital camera takes some research. If you ask yourself the right questions, however, the choices become clearer. The most important thing is that you get a camera you are excited about, one that you want to take pictures with, and one that you can take everywhere.



What is a digital camera?


A camera that creates a photograph in digital form and records on digital memory rather than film.


"Think of a film camera. You aim at a subject, press a shutter button, and the shutter inside the camera lens opens to expose light to film inside, capturing the image onto the film. You fill up the roll of film, take it to a lab, they develop it, and you have photos!

Ok, now you have a digital camera. You aim at a subject, press a shutter button, and the shutter inside if camera lens opens to expose light to a small sensor inside, capturing the image onto a memory card, instead of film. You fill it up, transfer your images to your computer, and can save them, alter them, print them, email them, and more! Even better, you can take your memory card to the local drug store photo lab, and insert them into a machine and have photo lab prints made .




Digital Camera Terms


Image Sensor- The image sensor is positioned in the digital camera where the film would normally be. When the photograph is captured the information is stored in the digital camera's memory.

Resolution- For digital cameras the resolution is usually expressed as a matrix of horizontal by vertical pixels. A resolution of 640x480 means the digital camera produces images that consist of 640 horizontal pixels by 480 vertical pixels.

Images Capacity- Number of images (pictures) that can be stored depending on the image quality mode.

Focus- Adjustment of the focal length setting on a lens to define the subject sharply.
Most digital cameras have a fixed-focal-length lens with close-up or macro setting. Some have zoom lenses or dual-focal-length lenses.

Focus Range- The range within a camera is able to focus on the selected picture.
Usually the focus range is listed for normal mode and/or macro mode.


Memory/Storage:

Built-in- The image storage method use two different techniques:
Built-in (internal) memory and removable memory.
Once the internal memory is used up by images, the user has to download and erase the images to continue taking pictures.

Removable-Removable memory is like a roll of film for conventional cameras that can be re-used over and over again.



How do I get my digital photos from my camera to my computer?

The pictures taken by a digital camera have to be extracted by some means in order to get them onto a computer, or perhaps directly onto a printer.

USB ports: Some specialized cameras may take advantage of the high speed Firewire protocol for connecting to a computer. Just about all modern computers come with at least a pair of USB ports, but not all computers include Firewire.

Use a Camera Dock: A camera dock can transfer photos directly from your camera to your computer.

Card Readers: Many people find flash memory card readers to be a quick and convenient alternative to using the camera’s native means of connecting. You simply remove the memory from the slot on the camera and pop it into the appropriate slot on the reader, and then the computer system can access the card like a local disk drive.

Memory card slot: Take the memory card out of your camera and place it directly into the memory card slot on your computer.
