Higher priced memory cards have a higher speed rating. This means that the picture is written to the card faster and the digital camera becomes ready to take the next shot quicker. This is really only an issue for anyone using digital cameras and wanting to shoot a number of pictures very quickly. It is also felt that the faster memory cards are of a little higher quality.
Compression Modes
Digital cameras use different compression modes to store images. If you use high or fine or super fine etc. compression modes then the image produced will be much sharper. Pictures taken at a high resolution will also take up more room on the storage card. Therefore if you are using digital cameras with relatively small storage cards then they will soon become full if you are shooting at a high resolution.
Digital Zoom
Digital zoom causes digital cameras to zoom in on the centre section of an image. The centre area will then look bigger, but the same number of pixels is used. This means that the quality of the image is reduced. If a zoom lens is important to you then make sure that you look out for digital cameras that come with an optical zoom. Digital cameras with optical zooms will produce images of a far higher quality.
