Lighting is a key element when you take a picture. Sometimes, the contrast between the bright and dark areas is extremely high. This usually leads to a reduction in the specifics of the picture.
Active D-Lighting captures highlights and shadows and ensures that they appear in the photograph. This function can be programmed to operate automatically, detecting the lighting conditions automatically or manually. Certain cameras are capable of creating two pictures that include Active D-Lighting, and another without.
Active D-Lighting applies at the exact time the picture is taken. Only those areas of the image which could be lost in detail are treated through optimization. Photos made using Active D-Lighting turned on will still display a natural contrast between dark and bright areas without losing the detail of the image.
