How to Change face skin in photoshop

Superb Skin Airbrush Technique

Airbrush skin like a pro. In this Photoshop retouching tutorial, you’ll learn how to retouch skin like the professionals. Find out how to make skin look healthy without looking plastic or blurred.

Step 1

Open the photo into Photoshop. For this tutorial, try to use a high resolution image where you can see the skin texture.
1

Step 2

Create a duplicate layer and put it into a group. To do this, press Ctrl+J to duplicate the layer then Ctrl+G to place the new layer into a group. Name the group "Airbrush" and the layer "Blur". To retouch the skin, there will be two layers in the Airbrush group. The first layer we’ve created (the Blur layer) will be used to blur the skin. After that, we’ll add another layer to restore the natural skin texture.

Step 3

Have the Blur layer selected. To blur this layer, use the Surface Blur filter. This filter blurs like the Gaussian Blur filter except it can retain edge detail. We’ll need to blur the layer so that the skin is smoothed and somewhat blurry without having the edges
3
Here’s what my image looks looks like after the Surface Blur filter. Your image should look similar with details such as the eye intact. If the eye becomes blurry, your settings are too strong. Undo and redo the Surface Blur filter with a lower setting.
4

Step 4

Create a new layer and move it above the Blur layer. Name this layer "Texture" and change the blend mode to Hard Light. This layer, as the name states, will be used to add a slight texture to the skin and also adjust the skin tonality.
5
The texture created in this layer will contribute to the final results very minimally – the difference can only be easily seen zoomed in on high resolution images and varies from image to image. Even though the result is very minimal, it ensures that no area of the skin looks too smooth or plastic.
Below is an example of this. On the left, the image looks like a solid color, also known as plastic skin. The image on the right has a slight noise pattern to make the skin look more realistic.

Step 5

Make sure that you have the "Texture" layer selected. With that layer selected, press Shift+F5 or choose Edit > Fill. In the Fill tool, set the settings according to the image below. This will fill your layer with a 50% gray color.
6

Step 6

Open the Add Noise filter from the Filter > Noise menu. Enter in the settings shown in the image below. This will add some noise to the image that will prevent skin from looking plastic. It may look a little too sharp, but in the next step, we’ll fix this with a Gaussian Blur filter.
7

Step 7

Choose Filter > Blur > Gaussian Blur. Blur the layer by 1 pixel.
8

Step 8

Now we’ll temporarily tint the color of this layer. First, select the Eye Dropper tool from the toolbar. Sample an area on the skin that appears to be the average skin color. You don’t have to be very precise because we will tune the color later in the tutorial. In the Color palette, click on the flyout menu below the close window button and select HSB sliders. We’ll need to see the HSB values for the next step.
9

Step 9

Open the Hue/Saturation tool by pressing Ctrl+U or choosing Image > Adjustments > Hue/Saturation. Check the Colorize option and adjust the hue, saturation, and lightness values to match the HSB values from the color we sampled in the previous step. For the brightness, set this to
10

Step 10

Select the Airbrush group in the Layers palette and add go to Layer > Layer Mask > Hide All. This will create a layer mask filled with the color black that will hide the group. With this layer mask, we’ll paint the areas were we want the skin to appear. Otherwise, this skin airbrushing effect will appear on the entire image.
11

Step 11

First, press D on your keyboard to set the foreground and background colors to the default black and white. Select the Brush tool and apply the settings below.
13
Zoom in to 100% and paint over the skin. The parts that you paint will appear smoother with a different skin tone. Don’t worry if the skin tone doesn’t look correct. This is because we didn’t pick the correct color when we used the Hue/Saturation to tint the "Texture" layer. It’s too difficult to do that without a preview, so we’ll fix that later.
When painting, you’ll need to change the brush size and hardness frequently. It would be tedious to always access the brush option menu to do this so take this as an opportunity to use hot keys. Use the following hot keys to help you with modifying the brush size and hardness:
  • Decrease brush size: [
  • Increase brush size: ]
  • Decrease brush softness by 25%: Shift + [
  • Increase brush softness by 25%: Shift + ]
14
When you’re done, your layer mask should have the skin areas in white and the skin should look smooth.15

Step 12

Now we’re going to fix back the color and tone of the skin as we mentioned earlier in the tutorial. Select the "Texture" layer and press Ctrl+U to access the Hue/Saturation tool. Alter the settings to get a natural looking skin tone.
  • The Hue setting is usually correct. I increased it by 10 to add more yellow to it to make the appearance of the red areas less visible.
  • The Saturation setting usually needs to be reduced greatly. Adjust this until the skin tone looks natural but not too pale.
  • The Lightness setting requires slight modification. A slight change in the lightness will create big difference in how the skin blends in with the image. As you adjust the setting, you will see how sensitive this setting is. Even though it requires high precision, it is easy to tell when it is the correct setting. If it is off, it will look really off. If it is at the correct setting, it will look a lot more natural.
16

Step 13

Finally, we’re going to restore the skin details. Choose Image > Apply Image. Use the settings below.
17
The reason why we’re applying data from the Red channel is because it contains the least skin imperfections. The image below shows the difference in the channels. The red channel hides many of the skin imperfections that are visible in the green and blue channel.

Final Results

Here’s the final results after applying this airbrushing technique. In the image below, you can see how smooth the skin looks. Because the image below has been downsized to fit into this tutorial, it may look slightly plastic. However, when zoomed in, the texture is clearly visible.
18
This is a crop of an area zoomed in 100%. The tiny skin bumps are still visible. Even near the bottom right of the image, it still looks natural because of the "Texture" layer that we added. Without that layer, that area would appear as a solid color with no noise.19
And as usual, here are the before and after images.

Howto create light effects in photoshop

Create breathtaking fantasy light effects

Learn how to combine brushes and blur effects in Photoshop to create a beautiful fantasy scene in this step-by-step guide by Murilo Maciel.

Fantasy art scenes are usually handled with a liberal sprinkling of Photoshop plug-in fairy dust – but you don’t have to slavishly follow that route. By creating your own brushes in Adobe Illustrator, and using scanned elements with Photoshop, it’s a simple process to create otherworldly scenes that are alive with glow effects and shafts of virtual light.
This masterclass takes a standard stock model – a super high-resolution version is included on the cover CD, or you can use your own – and applies layers of light and vector shapes to generate the main image shown left.
During this masterclass, you’ll learn to wrap your source image into a multitude of layers that add a fantastical theme to your art. The key here is to tread softly. When recreating fantasy light effects, soft brushes and fine application is the order of the day. Anything that’s too heavy can ruin the look.
The masterclass also draws on a element that some Photoshop users are reluctant to explore – that of physical art then added to the composition. Here, Murilo uses tools such as a toolbrush and screwdriver in addition to digital design tools to create the whirling snow effect.
Obviously, the final result is down to you, but you should also experiment with colours and blends once you’ve mastered this technique to create your own look. The best thing is you can create images like this without using a single plug-in.

Step 1
Open the file ‘wonderland.psd’ supplied on this month CD and create a new top layer. Fill the canvas with pink (C12 M30 Y0 K0) and change the blending mode to colour. Next, create another layer and select a soft round brush. Change the colour to a gold tone (C20 M15 Y65 K0) and set the brush size to 300px. Single-click on the middle of the canvas and resize this layer before you move to the top of your image for a smooth colour transition.



Step 2
To create a snow effect, you have to get your hands dirty. Get an old toothbrush, and dip it directly into the paint (but wait until it starts to dry – if your brush is too wet you can’t control where you throw it) To get depth in your illustration, shake a few, larger drops onto the paper first. Then, using a tool such as a screwdriver, quickly raking across the bristles, releasing the paint in a spray. Alter the speed of release and distance from the paper to created varied splatters. Alternatively, open the file ‘painting.jpg’ supplied on the CD.

Step 3
Scan the painting into Photoshop, and select Image>Adjustments> Desaturate. Go to Image>Invert, then select Image>Adjustments>Levels and increase the contrast, changing the input values to 60, 1, 244. Choose the best parts and import to your illustration.

Step 4
Change the blending mode to screen, and move this layer to the top. Open the file ‘model.psd’ and move the model to your illustration under the snow layer. Copy parts of the painting layer and place these mainly over her hair. It should be applied as a very soft detail that will help to blend her to the rest of the image.

Step 5
Now let’s create the heaviest ray of light. Create a new layer, and then make a rectangular selection from side to side and fill it with a white-to-transparent gradient. Make another selection as shown in the picture and hit delete. Go to Filter>Blur>Gaussian Blur and set the radius to 50 per cent. Rotate the layer and move it behind the model.



Step 6
We’ll now make softer rays of light to place over the model. On a new layer, create a selection with the same size as the one described in Step 5, then select a soft round brush and set the size to 2,500px. Brush outside the selection so it will look like the light is fading out from the top to the bottom of the selection. Duplicate the layer, flip vertically and move a bit lower. Merge both layers, resize, and duplicate them as you wish. As well as the snow layer, it should be applied as a very soft detail over her.

Step 7
Next, open Adobe Illustrator and create a custom brush. To do this, use the Elipse tool and create a symmetric oval shape as shown here.

Step 8
With the Selection Tool, select the point on the right side of that circle and drag it out to the right. Select the Convert Anchor Point tool (Shift+C) and click on the anchor point you dragged to get rid of the handle bars and make it a sharp corner. Do the same to the other corner.


Step 9
With the shape still selected, go to Effects>Warp>Flag and set the horizontal bend slider to 100 per cent. Select Window>Brushes and open the Brush palette. Move this new shape to the brushes window and select it as a new art brush.

Step 10
Start drawing a few shapes as shown and apply the brush you have just created. Try to make smooth lines and change the stroke size if needed. Copy your best shapes to Photoshop and go to Layer>Style>Outer Glow, and change the size to 150px and the blend mode to Colour Dodge.


Step 11
Have some fun experimenting with different settings and layer opacity. There is no limit to your creative freedom so always try different things. Once all the light’s shapes are done, change the layer order, moving some of them in front of the model and others behind the model.

Step 12
Create a new layer and change the blending mode to Colour Dodge. Select a soft round brush and set the colour to white. Go to the Brushes menu and change Spacing to 70 per cent, Size Jitter to 55 per cent and Scattering to 480 per cent. Start brushing areas on the canvas, altering the diameter of the brush and other settings as well.

Step 13
The image now is almost complete. Select a white soft brush and start placing various sized dots around the image on a new top layer. Pay attention to the model’s edges that don’t sit well with the rest of the image. This will help you create a convincing lighting effect.

Step 14
For the final touch add more elements to your illustration. Butterflies? Fairies? Why don’t you try to put some vector and hand-drawn elements? Put some dreamy music on and start thinking about elements which could fit to the subject. This is a very good creative exercise. Film is another great source of inspiration. When you think your illustration is done, flatten your image, convert to CMYK and go to Filter>Sharpen>Sharpen. You may have to increase levels and saturation as well.

Create a pencil drawing in photoshop

Manual drawing picture in pencil style

Even there are many kinds of plug ins and built-in effects for Photoshop, however a pencil drawing is beautiful or not, is depended
a lot on the artist. In this tutorial, I will help you draw a real pencil picture not use much effect like before.You art work will be more realistic than ever.

I would like to use this picture from this http://a17-lovely.hostico.net/f9.jpg . Pretty cool, huh ?
nguyenm
Step 1: Open the file
1-1
Then you go to [layer]>[new fill layer]>[solid color...] . In the opened dialogue box , you name the layer: ” nen giay” > [ok]
Another dialogue will appear, you use the same numbers below.

Press [ok].
Next, [Layer]>[new fill layer]>[pattern]. Name this layer is “nep giay” .
A window of patterns will be displayed. You click on that pattern, then click on the left arrow on the table below.

You choose ’artist surfaces’ —> [ok] . And seletc ’Burlap’ ( the third from left, firsts row). Set Scale is 30 %.
Set Blend Option is Ddarken, fill: 25%
Duplicate the background layer.

Name this layer is ’vien’.
Drag this layer on the op
Then go to [filter]>[Stylize]>[glowing edges]. Use the following numbers:

Press [OK]
Then you press Ctrl + shift + u in order to transform the picture to the black & white color.
Press Ctrl + I ( Inverse color),
Now the picture has the edge. Notice that there will be some big black lines, you should use the white brush to override them.

Set Blend Option is Multiply, Fill: 50%
Duplicate another layer from the background layer, name this ’ ve’. Again, throw it on the top.
Press Ctrl + shift + u in order to make it black & white color.
Then go to [images]>[adjustments]>[brightness/contrast]
Use the following numbers (you could change for your own pictures)

Then, go to [filter]>[noise]>[add noise]

Set Blend option is multiply.
Go to [layer]>[layer mask]>[hide all]
At this step. the layer ’ve’ has the mask, which hidden all of other layers.
Step 2:
Select Brush tool , use Dry media brushes :

Select the first on in this table

Press F5 in order to call the Brush Options panel, then make the following settings
- Brush Tip shape : + Roundness 20%
- Angles -120
- Shape Dynamics: + Control : Fade : 255
- Minimum Diameter : 16 %

Then, we are going to draw
- Firstly, we need to make a sketch. By changing Angles & Minimum Diamenter, we could adjust the brush suitably.
- Press [ & ] to increase and decrease the size of brush
- Press Shift + [ & ] to change the softness.

We need to apply some art technique when drawing, and should notice the setting of brushes.

After finishing, press Ctrl + Alt + E (combine all of layers).
Use the Burn tool ( O ) with the setting [ power : 10 -> 15 %]
Here is the final result:
