CX4 FAQs - By Product

[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 CX4, 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.
Also the Priority Range for the expansion effect (other than AUTO) is also selectable from [Highlights], [Shadows], or [Off].

The procedures for changing the dynamic range expansion effect settings

1 Turn the mode dial to Creative Shooting mode. Press MENU button to confirm the [DR] is selected. 1 Turn the mode dial to DR.
