Alien Effect
Open the photo you want to make into an alien. I am using a photo I found on a free stock photo site.
First, we need to duplicate the original layer and name our new layer: forehead. Lock your original layer. We will be using the liquify filter for this activity. Open it with Filter -> Distort > Liquify.
This will open the liquify dialog box. We need to set the brush size so that it is the size of the boy's head:
First we need to bloat the forehead. First you need to know what tools are available in the liquify filter. They are shown below:
As movies have indicated, aliens have a huge brains so we enlarge the top of the person's head. Pick the Bloat Tool and click on the middle of the forehead. Now hold the left mouse button or click repeatedly, whichever you prefer, the effect is the same. You will notice the top of the head getting bigger and bigger. Stop when you are happy with the result. Here is what I have so far:
Next, we need to duplicate the forehead layer and rename it: chin. Lock the forehead layer. We will need to shrink the chin. Select the Pucker Tool which has the opposite effect than the Bloat Tool. Place the brush on the person's chin and hold left button or click repeadetly until you have shrunk the lower part of the head to the appropriate size (for an alien:).
Now you will need to shrink the ears, nose and mouth. Each new edit will need its own layer. One layer for the ears, one for the nose, and one for the mouth. For the smaller parts change the brush size to a smaller size. Shrink the ears, nose and mouth using the same technique as in step 3.
Now we need to create alien eyes. Pick the Bloat Tool again and make the eyes a little bigger.
To add a slight smile, click on the Warp Tool, select a quite small brush size and drag the mouth corners up to make him smile. Click OK to close the liquify dialog box.
Now we need to add a green tint to complete the alien process. Create a new layer for this and title it: color. Click on Enhance -> Adjust Color -> Adjust Hue/Saturation. drag the Hue indicator to the right until you get a green hue you like. For an alien I think a slight yellowish-green will be great.
Drag the Hue indicator to the right until you get a green hue you like. The settings I used are shown below:
Here is my finished product.
