· Megapixels
The amount of megapixels in a digital photograph or image influences the quality of the image. This means that the more megapixels a photograph has, the higher the resolution of the images – and the clearer, crisper and more defined the image.
The size of the images a user wants to print is one of the determining factors when deciding on the ideal digital camera. If you are wanting to enlarge the prints of the photographs, you will need a digital camera with a much higher resolution.
With a 3 megapixel camera for example, you can print up to 250 x 300 mm good quality images, whereas a camera with 10 megapixels, such as the Panasonic DMC-FS20, can produce larger good quality images – and so forth. The more megapixels a camera has, the better the quality of the images it produces.
· Zoom
Digital cameras have two types of zoom functions: Digital zoom and optical zoom. Most cameras feature both zoom functions, and it is advisable to select a digital camera that offers both, rather than just digital zoom. If, however, you opt for a camera that features only one type of zoom, it is best to purchase a unit with optical zoom. The optical zoom ensures that high-quality photographs are produced when using the zoom function.
· Memory
Images are stored in the memory of a digital camera. There are two main types of memory: Internal or built-in memory, and expansion memory (removable memory).
The expansion memory is valuable to most digital camera users because it enables one to store more and more images as one’s photographic needs expand. Removable memory cards fit into the expansion slot, giving users the opportunity to purchase a bigger memory card, and hence capture and store a greater number of photos.
SD Cards are fast becoming the standard, highest performing, cost effective solution. It would be wise to choose a camera that supports this technology. Click here to see our range of camera memory.
· LCD
The LCD (Liquid Crystal Display) screen is an appealing feature of most digital cameras. The LCD allows a digital camera user to preview an image before it is taken, as well as to see images on the LCD screen after they have been taken.
· Connectivity
When purchasing a digital camera, a user should make sure that the camera has two types of connectivity – USB and AV Out.
The USB port is used to connect the digital camera to a computer. By doing this, images can be downloaded onto the computer and the full-size images viewed, edited and printed. It is important to ensure that the camera and computer are compatible with one another.
The AV Out connection allows a user to connect the digital camera to a television set, where image-viewing can be enjoyed on a larger screen.
