Card speed has no affect on image quality or a camera's speed of taking pictures. Card speed refers to how fast a memory card can move images from the camera's buffer to the card. Whether it makes any difference to your camera really depends on whether the camera can take advantage of the higher-speed cards. Most small digital cameras can't write quickly to a memory card, so card speed has little effect. High-end digital SLRs are definitely affected by card speed, but they also have large buffers, so card speed affects how many images can be taken by the camera before the camera has to stop to catch up on recording files from the buffer to the card.
Caught In The RAW
Q) I accidentally took digital pictures in the RAW format and now I'm having a hard time doing anything with them. I used the RAW image converter for my camera and converted them to TIFF, but I still can't e-mail them in that format.
A) Many cameras offer an image quality setting for storing images called RAW. RAW files offer some advantages as far as changing white balance after the fact and can allow for greater control of the image processing. Unfortu-nately, this all comes at a price.
Unlike JPEGs or TIFFs, the RAW file format isn't a standard. It's not even the same among a few manufacturers, so even if you tried e-mailing them, the people receiving the photos probably wouldn't be able to view them.
