[Question] What is a dynamic range expansion effect?

When you are shooting in dynamic range double-shot mode, the camera shoots two consecutive still images with different exposures and combines the areas with the appropriate exposure into one picture.
With the CX3, you can select from 5 expansion effects of the dynamic range (the range of brightness that can be processed by the camera) from [AUTO], [Very Weak], [Weak], [Medium], to [Strong].
The stronger the expansion effect, the wider the range of brightness that can be processed by the camera.

The procedures for changing the dynamic range expansion effect settings are shown below.

1	Turn the mode dial to DR.
2	Press the [MENU] button to display the shooting setting screen.
3	Press the [ADJ./OK] button to select [Dynamic Range Expansion] and press the button .
4	Press the [ADJ./OK] button to select the setting, and then press the [ADJ./OK] button. If you choose an option other than [Auto], and go to the [ADJ./OK] button right , the option menu of the Dynamic range expansion will be displayed. Choose an tone range option from [HIghlights], [Shadows], or [Off] to be given priority for the effect. Press the [ADJ./OK] button to choose an option, and press the [ADJ./OK] button.
