42 hp photosmart 930 series user’s manual
ISO speed
NOTE The ISO Speed setting does not apply to recording
video clips.
If you press OK when the ISO Speed
option is highlighted in the Capture
menu, 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 higher 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.
The default ISO Speed setting is Auto, which allows the camera
to pick the best ISO Speed for the scene. The ISO Speed setting
resets to Auto when you turn the camera off.
NOTE When you set the exposure mode to Action ,
Landscape , or Portrait , the ISO Speed menu option
is grayed-out, and the camera automatically selects the
best ISO Speed setting.
