Memory-card features

Оглавление

Instead of recording images on film, digital cameras store picture data on removable memory cards. Most cameras can hold only one card at a time, but some have two card slots. This feature is great because you can configure the two cards to perform different storage functions. You can put all your Raw files on one card, for example, and JPEG files on the other. Or you can send all files to both cards so that if one fails, the other provides a safety net.

Another thing to know about memory cards is that they vary in terms of capacity and in how fast they can record data. Larger cards hold more pictures and videos, and faster cards enable you to capture more pictures per second and record smoother videos. But not all cameras can take advantage of the highest-capacity, fastest cards. I won’t bore you here with an explanation of card capacity and speed specs (I save that for Chapter 2); for now, just know that if you do a lot of fast-action photography or video recording, this is a camera feature that matters.
