Not like expensive colour film that then requires even more expensive processing, digital media or memory cards for digital cameras require no processing before letting you see your images, and can be used thousands of times.
A single 1GB Sony memory stick, XD, SD, Compact Flash or Smart Media card can hold over 400 images (from a 5 megapixel camera). That’s more than 10 rolls of 35mm film used to take and - unlike film - you can use your memory card again and again!
There are many different types of memory card and it’s important to get the right one for your camera. A Digital Camera 4 U knows the type of memory different brands of camera require and provides a useful easy memory card finder here.
Memory card readers that sit by your PC and accept your camera’s memory card can both free up your camera (you can carry on shooting pictures with another memory card) and offer fast transfer of the images on the card
