Advanced' Photo Effects Forums

All you need is:

• 2 source images,
  
• a few layers,
  
• 1 Clone Tool,
  
• 1 Brush,
  
• 1 Layer Blending Mode
  
• and optionally 1 Layer Mask.

Please forgive my poor English, I hope that descriptions will be understandable.

OK. Open your sources in PS. I used an already retouched photo of the face and a slightly different source for the tongue. I hope you dont mind :)
