ps How can you not change the tone of the background when grinding

Duplicate the layer first to make it a habit to make it easier to modify Next, there are 2 ways to dermabrasion.

One is to press Q for a quick mask, then use a black brush to paint the area you want to polish, a white brush to paint out the facial features, press q to exit the quick mask, ctrl+shift+i to unselect and then use blur.

The second is to add a mask after the overall blur is to erase the parts that do not need to be blurred with a black brush.

As for the curve to adjust the character**, it is best to make a selection first, in fact, the previous mask selection can be used repeatedly, or you can add a mask and use a black brush to erase the unwanted parts.

And finally, it's best to get into the habit of stamping or duplicating layers when doing this step, and that's good for you.

It's also a layer mask.

If you duplicate a layer, apply Gaussian blur on top of that layer, add a layer mask, and use a black brush to paint on top of the areas that you don't need to blur (such as the background, the person's eyes, the lips, etc.), then the blur doesn't work on those areas.

Once you've made curve adjustments or other tonal adjustments to the layer, add a layer mask and use a black brush to paint where you don't want to adjust.

The Gaussian blur plus masking method doesn't affect the rest of the world in the first place, just blurs at the points you need.

As for using layers such as curve adjustment to adjust the color, if you want not to affect other parts, then select the character ** and then operate, or use a mask to black out the parts you don't want to be affected.

Use the Selection tool to select the part to be bruised, and copy it to a new layer for dermabrasion.

Use the Lasso tool to select the area of the grinding and then re-polish the skin (note that if the area selected by the Lasso tool is a bit stiff, you can use a feather selection command to select the value between 2-10.) and then rub the skin)

Use the Meitu App at the bottom of QQ Space** to choose a part of the dermabrasion in the beauty dermabrasion, which can achieve other skin grinding that remains the same, but the place where the brush has passed.

Before grinding, you need to make a duplicate of the skin, rub the skin on this copy, add a mask after grinding, and apply it with a black brush on a background that does not require dermabrasion, and it will return to the state before the dermabrasion.

It's really simple, use the dodge tool, which black eraser, is the same as the Meitu App.

It doesn't need to be a hassle.

Use the Lasso Tool to circle the ** you want to modify, then duplicate the layer, and then select Image-Adjustment-This is the color grading tool. After adjusting it, blur the edges, it is recommended to use "mask", so that PS only modifies the position you circled with the "lasso tool".

As for how to repair**, there are many tutorials on the Internet, and you can learn them.

Remember to make a backup.

I want to ask if you can use ps.,If you can't use it.,I said you might not understand.。

Make a copy of the layer first.

Use a tool like Curve to adjust the bottom layer to the color you want.

Then go back to the previous layer, create a "mask", and use the brush to paint the position you want to adjust. (It is best to set the brush to 0 Hardness, and the color of the brush can only be black and white during the "Mask", the black one is like a brush eraser, and the white one will make up the picture back).

Finally, if you think it's OK, just ctrl+alt+e to stamp a layer.

In this way, use the brush to wipe out the ** of the layer you have adjusted at the bottom in the "mask", and the background is still the same as before.

Find tutorials online to brighten your complexion.

Use the Lasso tool to select the face, and in the Image menu, select Adjust and select Modify in the menu.

Whatever method you use, you'll have to be region-restricted, so you can create selections in the areas you need.

1. Grade the image with color balance and curves.

2. Create a snapshot.

3. Use the "Noise, Dust and Scratches" filter for 1 pixel. will be smoothed.

4. Use the "History Brush" to restore places other than **.

5. Copy the image layer, select the clothes with a quick mask, reverse, and then add a "mask" to get the part of the clothes, and perform the "curve" to adjust the blue channel until the color of the clothes is reached.

Select the ** section and use the blur filter, Gaussian Blur.

However, please note that when performing "grinding" (Gaussian blurring of the character**), the values of each parameter should not be set too high. This is not going to work once, but it can be repeated many times. Microdermabrasion is a delicate job, so you can't be too anxious

In addition, you can use the "Curve" tool when grinding the skin, and adjust the hue, brightness and contrast of this ** file appropriately. In some cases, you can also add a light filter to make it contrast and feel sharper.

Specific production steps: copy.

1. Strike first.

Open PS software, File - Open (Ctrl+O) footage**.

2. We plan to remove the ** problem first.

Select the Stamp tool grooming. Set the size of the brush to about 20 pixels. Of course, this depends on the actual situation, and we must pay attention to the meticulousness of the retouching to ensure that the picture effect is real.

3. It can't be completely retouched, and at least a few small defects should be left. We have to leave some wrinkles to be more realistic. After retouching is the following ** effect, much younger.

4. Copy the background layer (CTRL+J). Decrease the saturation to 0 and convert it to black and white.

5. In the last step, select the top menu, Filter-Sharpen-Sharpen, and then we can take a look at the effect.

It depends on what method you use to dermabrasion, if it is high contrast.

To retain the dermabrasion, you will grind the skin first, because the high contrast retention of this special dermabrasion method will make the ** brighter a little, if you first put the tone good and then grind, the color will be very white.

My process is:

1. Fix the goofs, deal with the messy props or garbage on the scene 2. Repair the acne marks, scars, and wrinkles, because these things can't be rubbed off 3. Microdermabrasion, dermabrasion will remove some common problems, and after grinding, see what details need to be repaired to fix it.

4. Color mixing, it is recommended to have a curve, a little too even, mainly to adjust the relationship between light and dark and contrast, and then to see if there is a color cast that can be repaired with optional colors and color balance, after adjusting it, remember that if there is**excessive place and**insufficient place to trim it, **insufficient can not blindly use curve color level and the like, there will be noise, generally with imitation stamps. If the painting is good, the brush will do.

5. Reshape, use liquefaction to liquefy the thin and fat.

6. Sharpen it to make it clearer.

7. Finally, cut the picture, see what the composition is unreasonable, and change it.

PS character grinding and color mixing, depending on the specific situation and specific production requirements, using color scales, there are generally two methods of manual dermabrasion and plug-in dermabrasion, and the detailed production process is recommended to search for tutorials online, and it is not possible to explain them one by one!

Open ps, open your**, adjust** the curve, color level** contrast. For professional dermabrasion and whitening, you also need to install a plug-in.
