42 hp photosmart 630 series user’s manual
ISO speed
NOTE The ISO Speed setting does not apply when you are
recording video clips.
In the Capture menu (see page 35),
if you press OK when the ISO Speed
option is highlighted, the ISO Speed
sub-menu displays. This sub-menu
allows you to adjust the sensitivity of
the camera to light.
Because lower ISO numbers allow
slower shutter speeds, use the ISO 100 setting to capture
higher quality images that have the least grain or “noise.” In
contrast, because higher ISO numbers allow faster shutter
speeds, use a higher ISO Speed setting when taking either
pictures in dark areas without a flash, or pictures of fast moving
objects. However, higher ISO speeds produce pictures with
more grain or “noise” and, thus, can be of lower quality.
NOTE If you are taking a picture in low light conditions
without a flash and have set the camera to IS0 100, you
may want to use a tripod because of the resulting slow
shutter speed.
Tungsten The camera balances color assuming
incandescent or halogen lighting
(typically found in homes).
Fluorescent The camera balances color assuming
cool or warm fluorescent lighting.
