BASIC IMAGE RECORDING

■ About Auto Focus
• Proper focus may be difficult or even impossible when
shooting the following types of subjects.
— Solid color walls or subjects with little contrast
— Strongly backlit subjects
— Very shiny objects
— Venetian blinds or other horizontally repeating patterns
— Multiple subjects that are varying distances from the
camera
— Subjects in poorly lit areas
— Moving subjects
— Subjects outside the shooting range of the camera
• Note that a green operation lamp and focus frame do not
necessarily guarantee that the resulting image will be in
focus.
• If Auto Focus does not produce the results you want for
some reason, try using focus lock (page 82) or manual
focus (page 80).
■ About the REC Modes Monitor Screen
• The image shown on the monitor screen in a REC mode
is a simplified image for composing purposes. The actual
image is recorded in accordance with the image quality
setting currently selected on your camera. The image
saved in file memory has much better resolution and
detail than the REC modes monitor screen image.
• Certain levels of subject brightness can cause the
response of the REC modes monitor screen to slow
down, which causes some digital noise (graininess) in the
monitor screen image.
• Very bright light inside of an image can cause a vertical
band to appear in the monitor screen image. This is a
CCD phenomenon known as “vertical smear”, and does
not indicate malfunction of the camera. Note that vertical
smear is not recorded with the image in the case of a
snapshot, but it is recorded in the case of a movie (page
103).
