Taking Photographs—Beyond Point-and-Shoot
Image Quality
To reduce the amount of memory that each photograph occupies, images are
compressed as they are saved to the memory card. The camera uses
JPEG
compression, which analyzes images in blocks eight pixels on a side and selec-
tively reduces detail within each block. The more the image is compressed,
the smaller the resulting file and the less space it occupies on the memory card.
Compressing the image to make a very small file, however, may cause the block
pattern to become visible, and there may be noticeable loss of detail. The actual
effect depends on the size of the image when printed or displayed and on the
type of subject.
To select an image-quality setting, press the
button repeatedly until the
desired setting is displayed in the control panel or monitor.
