How many pictures and videos does a 1GB SD memory chip hold?

Answer 1

There is no magic number. It depends on the size of the image in pixels, the quality or compression selected and to a small extent, even the amount of detail in the subject. The pixels and compression options vary by camera model. You can usually change the settings between shots and end up with a mix of different sized images. In the case of video, the answer could be as little as one file.

The manual for the camera will have a table that gives you guidelines based on the settings it has. If you don't have the manual, you can look for an electronic copy or specifications on the manufacturer's web site.

Or, when the card is empty, you can set the camera for the picture size and quality you will use most and then see how many shots the cameras display says it has room for or how many shots are left.

If all else fails (for example, you don't own this camera yet and cant find specs), estimate the average file size you will be shooting using a similar model and divide that into the size of the memory card you are thinking about buying (both numbers must be in the same units. If you know the file size in megabytes, then change the card size to megabytes by multiplying GB times 1000). Don't use a sample photo of the sky or a plain white background. Take a photo with plenty of detail and color. [[User:Srobidoux|Srobidoux]]
