Zombify using Skulls and bones Effect in Photoshop

After finding a suitable source pic (1), First used Hue/Saturation, to decrease the overall saturation and make the colours greener, and did this especially near the lips (2). For the head, Looked for a picture of a skull which was taken from roughly the same angle (3), and used a layer mask to make it seem as if her eye had been taken out (4).

Adding details

In the neck area (1), Here used source pictures of a leg with spider veins (2), a mummy and a war victim (3). Source pictures which are usable for such a contest aren't always pleasant to look at… then experimented a lot with different blend modes, till it looked right.Finally decided the features of her body weren't clear enough, so did some masking adjustments to bring them back (4).

Dirty Laundry

The clothes (1) were soiled with a soft brush in red and greenish black colours, while using the overlay layer mode (2).

Finished

Finally it was time for some more detailed work.Took the image from (1) to (2) by, among other things:

• drawing little zits and such
• using hue/saturation very selectively to tone down the saturation and make some skin extremely green
• de saturating the hair completely
• using overlay, soft light and color burn layers and soft red and black brushes to add more shadow and bloody parts
