Most digital cameras, by default, save their images in JPG format.
JPG is a pretty good compromise between quality and file size for most users and in most
photographic situations. But what you may not realize is that you have a fair degree of control
over how aggressively your camera compresses the JPG images, and therefore the picture quality.
Take a look at your camera, and you will no doubt find that somewhere??”whether it is in a menu
system or controlled via a button on the camera housing itself??”there is a setting for image quality.
Note that image quality is quite different from resolution. Resolution is a measure of how many
pixels are in the image; quality determines how much color information can be stored in each
pixel and, consequently, how much image quality will be sacrificed when the image is saved.
Most cameras tend to have several quality settings, such as high, medium, and low. If you??™re
using the JPG format, I recommend that you always stick with the highest setting for your JPG
images??”the lower-quality settings can make for some pretty unsatisfactory images. On the other
hand, the highest image quality and resolution setting takes more space on your memory card,
reducing the number of images you can keep on a card at once.
