There are several factors that can cause the picture to appear grainy.
Using the digital zoom to take close-up pictures
Using the digital zoom to take close-up pictures
• With the digital zoom, part of the image is cropped and enlarged. The greater the
magnification, the grainier the picture appears.
Increasing the ISO sensitivity
• When you increase the [ISO] setting, “noise”, which appears as spots of unwanted color
or unevenness in the color, can be introduced and give the picture a grainy appearance.
This camera is equipped with a function to allow shooting at high sensitivity while
suppressing noise; however, increasing the ISO sensitivity can result in some noise,
depending on the shooting conditions.

Taking pictures with the
f mode set to M, W, S or X
• When taking pictures of dark subjects using the above scene modes, the picture may
appear grainy.
• The reason why there are sometimes differences between the actual colors and the colors
recorded in a picture is related to the light source illuminating the subject. [WB] is the
function that helps the camera determine the true colors. Normally, the [AUTO] setting
provides the optimal white balance, but depending on the subject, results may be better if
you manually adjust the [WB] setting.

• When the subject is in the shade on a sunny day
• When the subject is illuminated by both natural light and indoor lighting, such as
when near a window
• When there is no white in the center of the frame
• Often, bright subjects (such as snow) turn out darker than their natural colors. Adjusting
OF toward [+] makes the subject closer to their real shades. Conversely, when you are
shooting dark subjects, it can be effective to adjust toward [–]. Sometimes, using the flash
may not produce the brightness (exposure) that was intended.

• Set the flash to [
#] (fill-in) to activate fill-in-flash. You can shoot a subject against backlight
without the face of the subject appearing dark. [
#] is effective not only for shooting against
backlight, but also for shooting under fluorescent and other artificial lighting.
• Setting OF to [+] is effective when shooting against backlight.
• When [FACE DETECT] is set to [ON], faces in pictures appears bright, since adequate
exposure for the detected face can be obtained even under backlight conditions.
