How many pictures in a 256MB SD card?

Answer 1

The correct answer to this question is, "It all depends." Every camera resolution saves photographs of a particular size, and depending on your camera's resolution you can calculate the image size. As an example, a 4 megapixel camera, saves a 300 kilobyte file. So you calculate the capacity of your memory card as (1024x256)/300 = 800 images 1024 kilobytes make 1MB. 1024 multiplied by 256 gives you the capacity of your memory card in kilobytes. Divide that, by the size of your photograph, to arrive at the number of pictures your memory card can store. In my 12 megapixel Nikon D300 camera, I get jpeg images that are about 2.5mb, which in kilobytes workes out to about 2560kilobytes.

This in turn means that a 256 mb card can hold (1024x256)/2560= 102 photographs or so...

Answer 2

Depends on the quality of your photo:

* 3 Megapixels - 200 photos

* 5 Megapixels - 150 photos

* 8 Megapixels - 65 photos These are estimates, all images have slightly different file sizes

Answer 3

That depends on the resolutions of the photos (Megapixels) of your camera. Assuming its 3.2mp, a photo should be around 1mb, hence you can store 256 photos.

Answer 4

It depends upon the quality of the photos - the higher the resolution the fewer the pictures. If each photo were 1 MB in size, the device would hold about 256 photos.
