The number of pictures that you can store depends on several variables:
• The resolution of your camera. Higher resolutions or the more megapixels a camera is means larger files.
• The type of image compression your camera uses to create the image file. Highly compressed images require much less storage space than uncompressed, but image quality suffers. .tiff's are uncompressed files and .jpg's are compressed files.
• The amount of detail in the image affects storage requirements. A white car on a black background requires less memory on your memory card than a family grouping in front of a flower garden.
If you know the average file size of the resolution used by your camera, you can determine the approximate number of pictures you can store using a given capacity:
• Divide the available storage space by the file size. If the camera's resolution results in an average file size of 300kb (approx. 300,000 bytes), and you have a 16MB (approx. 18,000,000 bytes) flash card installed in your camera, then divide 18,000 by 300 - that's approximately 60 images.
