Below are three shots taken with Adaptive Lighting off, Adaptive Lighting on and using the built in flash, without Adaptive Lighting. All images are reduced size.

The light coming through the window has left the near side of the vase in shadow, with little detail visible due to the low dynamic range.

With the Adaptive Lighting switched on, the shadow areas are brightened and now contain visible detail. Unfortunately they also contain image noise.

The same shot taken with the built-in flash clearly demonstrates the difference proper lighting makes to an image.
