Choosing the right memory card for your digital camera
Table of contents
We know that most digital cameras use flash memory as image storage. Although film cameras use film more as a recording medium rather than storage, the premise is similar. Your digital camera should come bundled with the flash memory type required by your digital camera, but the capacity is usually small and will only be able to hold a relatively small number of photos or videos. A higher capacity flash memory card for your digital camera can make a lot of sense when you are away from your computer often and need to hold a large number of pictures in storage at any one time.
As there are many types of flash memory card in use today, it is extremely important that you identify the exact type your digital camera uses. This information can generally be found in the product detail specs, digital camera packaging, camera body as well as the user manual. If this information is not available, please be sure to ask for help from the camera manufacturer.
The next step is to determine the storage capacity that you will need. The higher the capacity of the flash memory card, the greater the numbers of photos you will be able to store. There is a wide range of flash memory capacities available today, starting at 64MB/128MB/256MB, and going as high as 4GB or more.
Images captured on a digital camera are saved as data files in the camera’s flash memory card. The image file size depends on image resolution (Megapixels), file format and image quality settings. Here is a matrix detailing the general relationship between flash memory capacity and the image storage capability (number of images that can be stored), which we hope can help you make the best decision.
Storage capability Matrix for Compressed Images
* Average size of compressed JPG format image with best image quality settings. If you choose a lower image quality setting, you will be able to reduce the image data size and store a larger number of images. Actual results are dependant on camera model and image compression settings.
Uncompressed images are only supported by professional level digital cameras (DSLR or SLR-like). Most compact and ultra compact digital cameras do not support uncompressed image files.
Storage capability Matrix for Uncompressed Images
* Average size of uncompressed RAW format image. Actual results are dependant on camera model and file format settings.
