There's more. Since there's not much in-camera processing on RAW images, they may require processing in an image editor before they look good. The files aren't compressed, so they take up much more room on your memory card. And they will take longer to write to a memory card.
Luckily, many popular image-processing programs will be able to take your RAW file and save it as a TIFF or JPEG file. Most image editors also have a batch function that will take a whole folder of images and create copies in the format you need. You also should be able to use the batch function to convert your TIFF files to compressed JPEG for e-mailing.
Making It On Television
Q) I've been trying to make a slideshow on a VCD of the pictures taken from a digital camera so that my family can view it on the TV using a DVD player. The problem I'm facing is the loss in the picture quality when viewing the same images on a TV; the pictures when viewed on the computer are sharp and clear, but when I create a VCD and test-run to see them on the TV, the pictures aren't as clear and are choppy.
A) The image quality problem you're having is caused by the fact that VCDs use a low-resolution format. Consider a typical computer setup (if there's such a thing as "typical"). The display resolution may be set to 1024 x 768 or even higher, and your display may be 17 or 19 inches measured diagonally.
Believe it or not, a VCD image size is only 352 x 240 in NTSC (the television standard used in the United States) and 352 x 288 for PAL (the standard used in many other countries). That's approximately one-tenth or less of the computer screen resolution. When you convert your images for recording to a VCD, you're immediately throwing away at least 90% of your resolution. You have no choice because of the format. Then you're blowing up the image to display it on a TV screen—probably larger than your computer monitor. You can see, then, why the image quality suffers!
