This guide is aimed at helping you clarify what all those technical terms mean when you are looking to Buy a digital Camera - Easy to use, just scroll down to the letter to find the word.

A

Audio Recording - This alows you to record audio to accompany an image or movie clip

Auto Exposure - This feature does all of the work for you - It automatically sets the lens aperture and shutter speed to allow the proper amount of light in

Auto Focus - This automatically focusses the lens on your subject. No need to manually adjust the lense

Auto White Balance - The camera will automatically compensate to match the true colour of the subject, so that 'real life white' looks white on the photo also.

B

Built-in Flash - On almost all cameras, a built in flash automatically provides an additional light sourse in low-light conditions.

C

CCD- The 'Charge Coupled Device' is an imaging device made of light sensing pixels and is inside every digital camera.The more pixels in the CCD, the higher the resolution and the sharper the images.

CCD Resolution - The maximum CCD resolution is the total number of pixels in the sensor.

D

Digital Zoom - This takes a small area of the image and digitally enlarges it - in effect stretching the pixels, so the image is not as sharp as optical zoom.

DPI - 'Dots per inch' More dots per square Inch of a printed image increases it quality.

E

Exposure Modes - This provides you with a variety of options which you can choose to deliver different effects, the longer the exposure, the morethe light will be allowed into the lens for a longer period of time and visa versa.

F

Flash - This allows you to light up dark subjects so they are more visable.

Flash Options - These include auto flash, red-eye reduction and it can basically be turned on and off

G

H

I

Image Capacity - The maximum amount of images which can be taken in high resolution mode before the memory card becomes full.

ISO Film speed Equivalency - ISO stands for 'International Standards Organization' and is a measure of the light sensitivity of a cameras film. The same measurement can be applied to the CCD of a digital camera. The higher the ISO rating, the more sensitive the camera is to light and can take pictures in darker environments.

J

K

L

LCD- This refers to the display screen on the camera and stands for 'Liquid Crystal Display'

Lithiium-ion - This refers to the rechargable battery. It can be refully charged after extended use.

M

Macro - This feature allows you to take a focussed image of a very close-up subject.

N

O

Optical Zoom - This uses the lens to magnify the image as opposed to doing it digitally. It allows you to maintain the image quality and resolution when you zoom into your subject. The higher the Optical zoom, the better.

P

Pixel - These are the elements which make up the display and image. The larger the number of pixels, the clearer the image or display.

Progressive Scan CCD - This reads all of the pixels on the CCD with one pass, for sharper images/

Q

R

Resolution - This determines the size of the photo you will be able to print without losing picture quality. The larger the the resolution, the bigger the picture you can print.

S

Self Timer - allows you to set a delay in the shot so you can take an image of yourself

Shutter Speed - The shutter speed determines the speed at which the 'door' to the sensor opens and closes, hense allowing more or less light in. Slower shutter speeds allow you to take pictures in low light when mounted on a sturdy tripod.

T

U

V

Video Output - Allows you to view the images or video clips on your TV and then record them on Video or DVD
