Smart Lighting is a DxO exclusive that includes a mechanism aiming at using the whole dynamic range from the image. It allows visual tonal adjustment with immediate results, rather than guessing how to draw the tone curve.
It solves most overexposures except for irreparable (real) clippings, which only the tone curve can fix.

Smart Lighting provides a result that looks like the dynamic compression of high-contrast scene lighting in advanced DC. It unblocks the shadows by preserving the light areas and recovers details in the clipped areas.

Smart Lighting does not replace exposure compensation, which must be activated beforehand if necessary. It avoids brightening the whole image.
Sometimes nothing happens, which can be confusing (when the image is bright and properly balanced). Sometimes it does a lot and the image gains density (a dark image becomes more toned). It is a prerequisite for the photography development and often brings the essential.

In order to keep the spirit of the picture, Smart Lighting starts in slight mode. Switch to Medium mode if necessary but avoid the strong mode which can be replaced by the tone correction.

The action of Smart Lighting can be guided with Spot Weighted which automatically detects faces. PhotoLab assumes that the humans are the subject of the photo.
When used manually the framing tool allows you to specify as many preserved areas as necessary, which can be one or more objects or different areas of a portrait.
– Activate the tool and draw as many rectangles as necessary

* The medium density framing tool focuses Smart Lighting’s action within the frame without affecting the overall rendering of an otherwise balanced image
* The framing tool applied to an area with extended dynamic range tells the Smart Lighting to preserve it and to take action on the rest of the image
* Microcontrast correction is limited on the Spot areas automatically created to limit its effect on faces
