The Program I used was Photoshop CS5.
Step 1: Choose a Photo
Select a photo and bring it into photoshop or any other photo editing program.
Step 2: Changing Skin Color
Go to image- adjustments – then vibrance
Decrease the vibrance to -100, and decrease the saturation to whatever you think makes the image look best.
Step 3: Altering Eye Color
Using the marquee tool select your eyes, and then color them a pale green.
Then use the marquee tool to create circles for the iris. Then color the iris a gray or white.
Using a round brush and a low opacity, color around the eyes different shades of gray and black. Changing the opacity between shades may add to the effect you what to achieve.
Step 4: Adding Color
Using the spatter brush at differing sizes and opacity, add pale green spots to the face and clothes.
Step 5: Adding Blood Effects
Changing brush sizes and the opacity adds to a bloody effect.
By changing the flow, you can make cool smudge effects.
Step 6: Cut Outs
Step 7: Finished Product
Using a variety of brushes and colors of reds and black, add blood to the Gouge, body, and walls.
Using Black and dark shades of blue and purple you can add bruises.
Brushes I used( other brushes can be used as well):
You can add a bite mark, as I did on my neck, using these tools and principles.
