Memory and Your Camera by 42nd St Photo

A digital camera uses a memory device instead of film to store the photographs you take, 42nd St Photo wants you to be able to use that memory effectively.

All your pictures in a digital camera are stored in the form of pixels. One million pixels equals a megapixel, and that is the unit of measurement you generally will see mentioned as resolution. A higher resolution photo has more megapixels…more units used to make the picture…and it will use more storage space on your memory card.

Memory cards store information in binary form, similar to an on/off switch. A simplified way to look at the way storage is measured is this: One binary digit is one bit, 8 bits is one byte, 1,000 bytes is a kilobyte(KB), 1,000 kilobytes is a megabyte(MB), and 1,000 megabytes is is one gigabyte(GB).

A 128MB memory card will hold 91-100 images at 4 megapixels but it will hold only 38-42 images when they are taken at 8 megapixels. A larger card can be used if your camera is compatible: a 1GB card, for instance, will hold 724-800 images at 4 megapixels and 301-333 images at the higher resolution of 8 megapixels.

42nd St Photo carries a variety of cameras with various storage capabilities. You need to know your own camera and its storage requirements because not all sizes of memory cards will be suitable for your device. It is frustrating to purchase a 1GB card to take all your vacation pictures and discover that your camera cannot process that amount of information.

If you are not sure what sizes of memory cards are compatible with your camera, look in the manual or contact 42nd St Photo for the expert advice that will allow you to keep your photographs safe on the best memory card for you.
