How many pictures can you take with a 4gb memory card at 12 megapixels?

Answer 1

Expandable memory cards can range in size from as small as 16MB, all the way up to 4GB (4 Gigabytes or 4,000,000,000 bytes / 4 billion bytes), and range in price from $20-$200. The chart below will give you a basic outline of how much memory a digital image will take up on different size cards, and with various output resolutions. Please remember these are approximate numbers of images; results with your camera may vary.

Resolution / Mega Pixels

Capacity 3.0 MP 5.0 MP 8.0 MP 10 MP 12 MP

16MB 10 9 5 2 2

32MB 25 17 10 5 4

128MB 150 120 80 55 32

256MB 300 240 160 110 71

512MB 600 480 320 225 121

1GB 1200 950 600 400 260

2GB 2400 1900 1200 800 500

4GB* 4000 3000 2000 1500 1000

Answer 2

**The question is obviously in relation to how much internal memory a camera can store. Many current digital cameras include 12MB of internal memory. The answer is not many at all. Perhaps 5-10 at higher settings. Use the information below to guide you to getting an additional memory card.**

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: My 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 3

It depends on the file format and resolution of the photos. Photos are usually stored in the .jpeg file format. If so, a 12 mega pixel photo has a size of 3-4 mb and a 2gb card can approximately hold 500-650 photos.

Answer 4

How many pictures a memory card can hold depends on display settings and the camera brand. Most cameras will hold 800-850 pictures on a 2GB memory card.

Answer 5

This is dependant on the resolution setting, the higher the setting the lower the number of photos that will fit on the card.

Answer 6

Megapixels are not always the deciding factor. Zoomed pictures take up less space.

Answer 7

It depends. Some factors include if you shoot in RAW or JPEG, level of compression, and camera model. My rough estimate is 150 JPEGs on low compression.
