Note that the above scene contains roughly three tonal regions with abrupt transitions at their edges - therefore requiring a custom-made GND filter. Scenes which are ideally suited for GND filters are those with simple lighting geometries, such as the linear blend from darker land to a brighter sky in landscape photography: This is because GND filters extend dynamic range while still maintaining local contrast.

Only use HDR when the scene's brightness distribution cannot be easily blended using a graduated neutral density (GND) filter. High dynamic range imaging utilizes this characteristic by creating images composed of multiple exposures. By varying the shutter speed alone, most digital cameras can change how much light they let in by a factor of 50,000 or more. The 'bright side' is that nearly any camera can actually capture a vast dynamic range - just not in a single photo. Furthermore, some scenes simply contain a greater brightness range than can be captured by current digital cameras - of any type. This is particularly apparent in modern compact cameras with 8 or more megapixels, as these are more susceptible than ever to blown highlights or noisy shadow detail. MOTIVATION: THE DYNAMIC RANGE DILEMMAР”Р„s digital sensors attain progressively higher resolutions, and thereby successively smaller pixel sizes, the one quality of an image which does not benefit is its dynamic range.

Learning to use HDR software can help you make the most of your dynamic range under tricky lighting - while still balancing this trade-off with contrast.

There is no free lunch however trying to broaden the tonal range will inevitably come at the expense of decreased contrast in some tones. Image above courtesy of Kyle Kruchock (albeit in a heavily modified form).
