solves a problem, which can be achieved through various methods, not only with only one method. Once we understand this principle, we can derive many solutions to the problem.
The most commonly used method of removing dust from photos is to realize it by dragging to the right to remove mist slider in Camera Raw.
But in the article ", don't destroy the picture! You must understand the difference between clarity, removal of mist and texture in ACR, ", I have a special discussion on removing mist:
It mainly improves the global contrast of dark parts, middle tone and bright parts, but in order to prevent the highlighted areas of the landscape film from being overexposed, the brightness of the highlighted areas slightly darkened the brightness of the highlighted areas in the algorithm, but this is very subtle, and the real thing to become bigger is in the dark parts and the middle gray.
But the removal of mist is associated with saturation, that is, if we use removal of mist, the colors in all images will become bright.
We can also remove graying photos in Photoshop, and use the gradient mapping adjustment layer to achieve it.
First, in the " Adjust " window, select the last icon with a gradient from black to white, which is gradient map .
Click on it to add a gradient mapping adjustment layer. Then, we click the gradient icon on the left side of the layer, and the " attribute " window will pop up.
If we continue to click on the gradient bar in the "Properties" window, " Gradient Editor " will pop up. You can choose a bunch of various colors and metal gradient textures. Don't pay attention to them. These things are related to what we want to use here, and they don't have to be distracted by them. What we have to do is to remove the graying.
We use the default first type in the basics, which can be changed from black to white, and the picture will become black and white .
If the picture does not turn black and white, it becomes a negative negative effect like the above picture. Don't panic, that means that your foreground color has been selected in reverse, and there is no need to return and modify it. Just type the box in the attribute " reverse " to turn back into the black and white effect.
Then we change the blending mode of this adjustment layer to " brightness , remember to change it to "brightness", basically completing the graying function without changing the saturation of the image.
If you think the effect is too strong, you can reduce the layer opacity in to reduce the effect; if you think the effect is not strong enough, you can copy one or more gradient map adjustment layers on this basis, and adjust the opacity of the top adjustment layer, and make precise adjustments until the picture looks appropriate.
