There is a вЂCheck MaskвЂ™ box at the bottom of the window to show the control point mask as an overlay to see which areas itвЂ™s selecting. ItвЂ™s not had much effect, though, so I suspect the default mask is too selective. IвЂ™ve placed a control point over a sunlit pat of the car, increased the radius to include the whole car and made some adjustments to reduce the exposure and increase the saturation and vibrancy. A control point adjustment is ideal here because it can quickly target the color and area I want to fix. This classic car was in part sun, part shade, so the exposure was always going to be a compromise and the color does look pretty undersaturated. HereвЂ™s a sample image I can improve with some selective adjustments. HereвЂ™s a run-through of how PhotoLab control points work, and how and when to use the new chroma and luma sliders. What the new chroma and luma sliders do is allow you to fine-tune the sensitivity to make the control point mask either more or less selective.ДxO PhotoLab 5 control points and chroma and luma sliders in action So already, PhotoLabвЂ™s control points are pretty selective. As you move it, the central point will move too and will change the mask to reflect the tones directly underneath it in its new position, applying the same adjustments but to a different area. You can change the size of the control point (the radius of its effect) and you can also move it around. PhotoLab control points are for making quick and powerful local adjustments in a way thatвЂ™s quite unique and different to any other program.Д®ach control point works over a circular area but creates a mask automatically within that, based on the colors and tones directly under the central point.Д®ach control point has pop-out controls for adjusting, exposure, contrast, saturation, white balance and more. So how do these control points work, are they useful and do the new sensitivity sliders make a difference? Now itвЂ™s enhanced them with chroma and luminance sensitivity sliders.

PhotoLab control points were inherited from Nik SoftwareвЂ™s clever U-point local adjustments (aka control points) when DxO took over the Nik Collection.
