Local adjustments
 that give you more

From brightening faces in treasured portraits to darkening the sky of a dramatic landscape, local adjustments are a vital part of producing quality photos that are exactly as you imagine them.

In traditional software, making them is tricky and imprecise. With U Point local adjustments, that’s no longer the case.

Rather than ‘global’ adjustments that affect an entire image, local adjustments mask off just small elements within the frame. Traditionally, these need to be made with selection tools. You outline the area you want to edit, then make the changes.

But without expertise, manual selections can be time-consuming and inaccurate. 
If you’ve ever tried to use magic wands, freehand lasso, and pen tools or make selections using channels, you’ll know all about it. Even with lots of skill, some situations are impossible to mask accurately.

There had to be a better way, and in the early 2000s, Nils Kokemohr (founder and former CTO of Nik Software) and his team of engineers invented it. U Point is a revolutionary, award-winning technology that makes selections with incredible precision based on just a simple mouse click.

After DxO purchased the Nik Collection from Google, we redesigned and upgraded U Point technology so it could be used on RAW files. All the edits you need to make can be achieved without leaving DxO PhotoLab, our advanced photo editing package.

How U Point works

The U Point tool literally lets ‘you point’ to the part of the image you want to edit. A single click, for instance on the skin tone of a portrait, identifies those colors and tones as a reference point, called a Control Point or Control Line. This radius of the area around the Control Point can be fine-tuned. Similarly, Control Lines can be altered in width and angle to cover different regions of the image.

Once these reference points are created, the U Point algorithm identifies the pixel’s characteristics in terms of color channel value (red, green, and blue), hue, saturation, and luminance.

But that’s not all

U Point technology also analyzes the appearance of the surrounding area in the photo to distinguish between similar pixels based on their color and texture. Hues and tones are grouped into the area to be adjusted based on this analysis.

Two separate sensitivity sliders let users differentiate between similar pixels with an extreme level of precision. These add or subtract from the selected area based on Luminance – how bright it is – and Chrominance – its color. As a result, masks can be endlessly fine-tuned.

Another huge benefit of U Point technology is that users can add  as many control points as they want in order to:

Address multiple issues with a variety of specific adjustments 
Add redundancy: since similarities are analyzed in every Control Point and Control Line placed within your image, the engine is able to distinguish one reference pixel from another and figure out how similar they are 
Select areas that are non-circular in shape more easily 
Expand the selection to include slightly darker or lighter reference points 
Identify different reference pixels on different objects
