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.

Guy

We will be using the liquify filter for this activity. Open it with Filter -> Distort > Liquify.

Liquify Filter

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:

Liquify Dialog Box Tools

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:

Bloated Forehead

Next 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:).

Pucker Chin

Now you will need to shrink the ears, nose and 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.

Alien Eyes

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. 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.

Adjust Hue and Saturation

Drag the Hue indicator to the right until you get a green hue you like. The settings I used are shown below:

Green Tint

Here is my finished product.
