Digital Cameras
Digital cameras have fast become the majority of peoples first choice choosing a new camera. The main advantage of digital cameras is they do not require films. The images are stored digitally on the camera, normally in a removable card called a memory card. The pictures taken on a digital camera can be transferred onto a computer. From there you can email the pictures to friends and family or print them on photo printers.
Megapixal
Digital images are built up from millions of tiny dots called pixals. A megapixal is a million pixels. A digital cameras image quality is measured in the amount of megapixels the camera can capture. The more pixals in an image the better the quality. For printing a 6" x 4" photo we recommend at least a 2 Megapixal camera. However the more megapixals the camera offers the better the image quality. It's fairly standard for the latest digital cameras to offer image qualities of 5 megapixels or more. A 5 megapixel camera is suitable for printing an A4 sized photo.
LCD Screen
Digital cameras have an LCD screen that allows you to view the images you've taken. Modern digital cameras are starting to use the LCD screen as a replacement for the traditional view finder. The larger the screen the better, we recommend buying a digital camera with at least a 2" screen.
Optical Zoom
An optical zoom enlarges the image using the lens. An optical zoom still enables a digital camera to capture the image without any loss in image quality. Typically a digital camera that provides optical zoom will have a 3x zoom.
Digital Zoom
Digital zoom is an artificial zoom effect. The quality of the image is reduced to create a zoom effect. It's like cropping the image and then enlarging the cropped image.
Memory Card
A memory card is used to store the images you take. The memory card is interchangeable between compatible cameras. Memory cards come in a variety of sizes to suit your budget. We recommend purchasing a memory card of at least 512MB. You should also check which type of memory card each camera takes as some can be much more expensive than others.
USB
USB is a means to connect your digital camera to your computer. All modern desktop computers and laptops support USB.
Digital SLR Cameras
Digital Cameras that also allow manual focusing are known as Digital SLR Cameras. Most will allow auto focus and manual focus. Digital SLR cameras provide a greater flexibility and as such are used by professional photographers.
