How many pictures can a 512Mb memory card hold?

Answer 1

Answer

it depends upon the picture size

for example if the picture is of size 200kb then a 512 MB memory can store approximately 2560 pictures

A good guide is available at http://www.lexar.com/digfilm/capacity_chart.html It includes a chart indicating how many pictures you would be able to save depending on the megapixel count and the size of the memory card.

Answer

If you have one, your User Guide/Instruction Book/ on-screen Manual should be able to help you. For example, I have a Canon A710IS of 7.1MP, and under "Memory Cards and Estimated Capacities" for a 512 SD memory card it it goes from 156 for 'Large (3072x2304 pixels)' to 839 for 'Postcard (1600 x 1200 pixels)'. (If you don't have a Manual go to the web site above)

Answer 2

The number of images any card can hold is a factor of the size of the image - most camera have two, or even three or four sizes - for example, SMALL, MEDIUM and LARGE. Obviously, a card can hold more SMALL images than LARGE. So there is no pat answer to your question - you need to check your camera's instruction booklet, it should tell you what size images you can store, and perhaps even a matrix of images sizes and card capacity.

Answer 3

The capacity of a card indicates the maximum amount of data that can be stored (less some space for the card's own use).

Megapixel (MP) count refers to the maximum resolution of the camera's sensor -- its ability to record detail. The number of images that can be recorded on a card of a given size is only indirectly related to the capacity of the card, which is measured in Kilobytes (KB) or Megabytes (MB), not MP. That will vary according to the image itself, and to the camera's settings.

For example: a Pentax K10D, with a 10.1 MP sensor and using a 4 GB card, will record approximately 821 images at the highest resolution (10 MP) and a "Fine" resolution setting. The same camera, with the same sensor and same card, will record 10,000-plus images at the lowest resolution (2 MP) and the "Low" resolution setting. Practically all cameras have this ability to change the resolution settings, and thus the sizes of the image files that are stored on the card.

So, you can see that it is only possible to answer your question in very general terms: The higher the capacity of the card, the more images you can store at whatever camera settings. And, as you can see above, even at the highest settings with a high MP count, you can take a lot of pictures!

One thing to think about: storage cards can and do fail. It is better to have two 1 GB cards than one 2 GB card, unless you plan to shoot a whole lot of video. That way if one fails, you can keep shooting and worry about retrieving the images off the other card later.

Answer 4

Depends on the size and quality of the pictures.

Answer 5

Depends on compression and pixel count

Answer 6

It depends on the size of the pictures.
