Photoshop darkened/Highlight Operation tutorial

The tool was used in the previous lesson to modify overexposed and overexposed photos, and the purpose of developing this tool is to repair digital photos. A large setting box appears when you start the darkened/Highlight adjustment tool and check "show other options" below. It is divided into dark tune, highlight, Adjustment 3 most. Now set the number of highlights to 0%. Take a look at the adjustment effect of the darkened tone alone. The effect of the darkened part is to increase the brightness of the darkened part, thereby improving the exposed parts of the photo. It can also be called compensating for darkened tone.

The larger the number, the higher the degree of increase, now maintain tonal width of 50%, radius 30 pixels, the following 3, respectively, the original, number 50%, the effect of the number 100%.

Tonal width, a bit like the concept of the color tolerances involved in explaining the magic wand tool in the previous lesson. Here the tonal width is darkened to change the size of the range, tonal width about large, the more the brightness involved, the effect of change is more obvious, but instead. The following 2 figure is the effect of setting the tonal width to 50% and 100%.

The concept of a radius is similar to the tonal width above, but the tonal width is for the whole diagram. The radius is for the size of the darkened area in the image. Their differences are somewhat similar to the proximity selection of the Magic wand tool and the choice of non neighboring selections. Therefore, the radius of different images is also different, in theory to adjust this value to the image and need to adjust the size of the region similar. However, it is not easy to judge it in practical use. Therefore, the suggestion is to make compensation for darkened operation, try to pull left and right to adjust to the most comfortable visual values.

The effect of the high light adjustment is to reduce the brightness of the high light part of the image, also known as high light suppression. There are also a number, tonal width, radius of 3 items, they are the same principle and the previous dark tone is the same. Below we first turn off the effect of compensating darkened (set the number of darkened to 0%), try to set the highlight as follows: Number 50%, tonal width 50%, radius 30 pixel effect, compared with the original image below, above for the original image.

Before explaining the darkened part, tonal width and radius of the difference between the two concepts, we may not see very clear. That's mainly because the human eye is insensitive to darkened changes and is not easy to compare. Now we can demonstrate their differences in the high light, the effect is more obvious. The following 4 diagram illustrates the difference between tonal width and radius changes. Because the amplitude of the image change is not very conspicuous. We have to actually operate in Photoshop, moving around the slider, there will be a relatively clear sense of contrast.

The Color correction option below is used to control the color concentration of darkened or high light areas, and it is important to note that if the dimming compensation or the high light suppression value is 0%, the color correction has no effect on them.

The middle contrast is to control the middle of the adjustment bias darkened, or biased to the high light, the effect of the figure 2 figure.

The bottom of the "black clip" and "reduce white pixels" two options are the same as in the curved tool of the merged darkened area or merge the high light region. Mediation requires subtle, too large numbers can cause serious distortion of the image. The effect of the following figure is to set the dimming compensation and the high light suppression to 50%, 50%, 30 pixels, and then set the black clip and reduce white pixels to 20%.

The last "Save as default" button has the effect of setting this time as the default for each use.
