How does Lightroom use tutorials to enrich lr highlights?

1

Adjust the white level in the basic panel.

For photos, we need to make the brightest part of the picture (white clouds) close to the right side of the histogram, so we need to use "white levels" instead of "highlights". The specific operation method is: pull the "white scale" slider to the right (or directly enter a positive value), and observe the histogram at the same time, so that the highlight area is close to the right side of the histogram, but it does not overflow.

Here's a trick: there is a small triangle in the upper right corner of the histogram. When the triangle has no color, it means that the histogram does not overflow; When the triangle appears red, blue or green, it means that the corresponding color channel overflows; When the triangle turns white, it means that all three color channels overflow. The small triangle in the upper left corner of the histogram indicates the dark overflow (in this photo, the dark overflow).

Adjust the brightness tone in the tone curve panel.

Let's go back to the original film-all adjustments-Lightroom's adjustments to photos are non-destructive, which means that you can go back to any previous step at any time (even if you have closed the software and then reopened it). In fact, before the output, all the actions you do in Lightroom are a separate mark, which will not really affect the original file. So as long as you don't replace the original file with the output new file (which should not be the case), you can modify the previous editing work at any time in the future.

Anyway, this time I will use the "tone curve" to adjust the photo. Lightroom's "tone curve" is similar to the curve in Photoshop, but each has some characteristics. For example, Lightroom divides the curve segment of a photo into four parts: highlights, highlights, shades and shadows. This division actually does not affect the function of the curve, but it is easier for photographers to understand.

When adjusting the Brightness Tone, refer to the small triangle in the upper right corner of the histogram to ensure that it does not overflow.

Adjust the highlights in the Tone Curve panel.

Back to the original film again, this time we will try the last tool-"highlight" curve.

The difference between "highlight" curve and "highlight" curve is that the former has a smaller influence range. In Lightroom, "bright tone" refers to most of the upper half of the curve (almost 2/3), while "highlight" refers to the brightest part in the bright tone area.

Matters needing attention

Whether it is "white tone", "bright tone" or "highlight" curve, you can find a white field for the photo. With the help of histogram triangle, we can make the histogram as far as possible to the right without overflowing. But these three tools have different effects on photos. The processing of the color scale tool is linear, which will have the same effect on all parts of the whole photo; The "bright tone" curve only adjusts the bright tone area of the photo (the middle and dark parts will also be affected, but to a lesser extent); The Highlight curve limits the influence to a smaller range than the Highlight curve (the middle and dark parts are less affected). In use, different photos may need different tools.

In addition to post-processing skills, I hope you will also notice that I intentionally underexposed the sky when shooting, so as to preserve the level of clouds and obtain a more saturated sky color. This is because I have planned the post-processing method when shooting. If you don't control the exposure well when shooting and lose the highlight level (which is common when shooting a scene with large light ratio), then there is nothing you can do at any later stage.
