Applications
: Select an ISO value. This controls camera light sensitivity. Low values are for
stationary or brightly lit objects. Higher values are for fast-moving or poorly lit
objects. However, higher ISO settings can result in noise in photos.
If the shutter speed is set manually, you cannot set the ISO setting to Auto.
: Adjust the shutter speed. A slow shutter speed allows more light in, so the
photo becomes brighter. This is ideal for photos of scenery or pictures taken at
night. A fast shutter speed allows less light in. This is ideal for taking photos of fast-
moving subjects.
: Change the exposure value. This determines how much light the camera's
sensor receives. For low-light situations, use a higher exposure.
If the shutter speed is set manually, you cannot change the exposure value. The
exposure value will change and be displayed based on the shutter speed setting.
Saving the current setting as a custom setting
On the preview screen, tap Custom → Save current settings, select a name, and then
tap SAVE.
To apply the saved settings to the camera, open the preview screen, tap Custom, and
then select a name.
Separating the exposure area and the focus area
If bright light affects the contrast or the subject is outside the auto focus area, use this
feature to achieve an appropriate exposure. You can separate the exposure and focus
areas and select the exposure level you want for the subject.
This feature is only available when you set the shutter speed and the focus to
Auto in pro mode.
The AF/AE frame will appear on the focus area.
