Digital Camera Memory Types

The Memory Storage

The higher the Megapixels, the larger size the image to be stored will be. Most cameras give you the option to adjust the level of image to reduce space required. With My 3.1 M.Pixel camera on a high setting, results in images of approx 1.2MB in size.

Your images need to be stored somewhere before playback and editing and with cameras that means on the memory card. Some cameras also include a small amount of memory built-in.If you work using the table below you can work out what size of card to use again we would recommend 64MB for the occasional user, and 128MB as a minimum for the heavier user.

Card		64MB	128MB	256MB	512MB	1GB
1 Megapixel		182	365	731	1462	2925
2 Megapixel		71	142	284	568	1137
3 Megapixel		53	106	213	426	853
4 Megapixel		32	64	128	256	512
5 Megapixel		25	51	102	204	409

Battery life

The first thing people new to Digital Cameras notice is how quick they go through a set of batteries. People recommend different types of batteries but I would always recommend a branded set of high rated NiMH (nickel-metal hydride) rechargeable batteries.These can cost £10-£20 but provide a good length of usability and can often be re-charged within two hours.
