Quick Digital Card Question


How many pictures will a digital card hold if the card is 6 GB and the camera is a 8.0 megapixel camera??? Set the highest resolution?

Please help!

Phillip Corcoran   The camera info display should tell you once you slot the card in and set the picture quality. Since the quality setting varies between different brands of 8MP cameras (which in turn affects the file size) I can't say exactly how many you'll get. But my 8MP Olympus E-300 gives me this on a 1GB card:
1. Highest quality JPEG = 158 shots
2. RAW = 72 shots

So if I had a 6GB card, based on those figures above:
1. Highest qual jpeg (158x6)= 948
2. RAW (72x6) = 432

So on your camera you should get roughly the same, allowing for the differences in camera brand and model my figures will not be that much different to what you would get since both cameras are 8MP.

Hope that helps.

  Using the Canon Rebel XT 8MP as an example:

Largest JPEG is approx. 3.3MB

6GB card would hold approx. 1800 JPEG images.

RAW file is approx. 8.3MB

6GB card would hold approx. 700 RAW images.

Image size varies, this is just an estimate based on the typical sizes quoted in the camera specs.

  Phillip & I were typing at the same time, but it looks like our examples are pretty different.

Deborah - RAW or JPEG?

You can see from the file sizes that RAW images have more information in them. RAW images will give you more detail, a wider exposure latitude, and more flexibility for image adjustments after shooting. A RAW image will give you all the information that the camera's sensor captured. A JPEG from the camera will have some processing applied to it, then it will be compressed, so you don't get the full amount of data that was captured.

If you want the highest quality image you can get from your camera, and you are prepared to do some post-processing of the image on your computer, then you would want to learn more about shooting in RAW.

If you plan to go direct to printing, without any editing on your PC, you will need to shoot in JPEG. If you will be bringing your card directly to a lab or a kiosk or sticking it in your printer, you'll need to shoot JPEG.

Phillip Corcoran   Deb, my figures are lower than Chris's because my camera makes bigger files than his:
1. Highest Qual jpeg is approx 6MB on mine.
2. RAW files are approx 14MB on mine

We are both right for our own cameras, if you see what I mean. All to do with file sizes being different.

Wayne L   Will a Canon xt take a 6GB card? I understand some of the larger CF cards won't work in some cameras.
