Reference-Advanced Photography Image Quality To reduce the amount of memory that each picture 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 selectively 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. / Scene IMAGE QUALITY QUAL FINE 1 SIZE NORMAL BASIC S A MENU O F F SELECT SET The image-quality menu contains the following options: Option FINE NORMAL BASIC Description Fine image quality, suitable for enlargements or high-quality prints.
