GR DIGITAL III FAQs - By Product

[Question] Let me know about the Dynamic Range Double shot.

'The dynamic range' of digital cameras refers to the range of brightness that can be processed by the cameras.

With Dynamic Range Double shot, two consecutive pictures are taken with different exposures and then the areas with the appropriate exposure are combined together.

Images below are simulated.

When you shoot a scene with high contrast, such as both a sunlight area and a shade area, the bright areas will be over exposure, and the image may not look natural. This is because the range of brightness that can be processed by the camera is narrower than that of the human eye.
With the Dynamic Range Double shot, the scene is reproduced with a smooth transition from the bright areas to the dark areas, allowing you to capture a more natural-looking image.

[Caution]
Be sure to use a tripod for the Dynamic Range Double shot, since this mode uses a longer shooting time than other modes. The Camera shake warning is always displayed.

Even if you use a tripod, camera may move when you press the shutter release button. In such a case, we would recommend using the self-timer feature, or a cable switch (CA-1, optional).
