Swapping Faces. (Extract tool)

This is the most sought after technique in photoshop. You see it all the time on the web and even sometimes in advertisements. To do this you have to have two pictures. The first picture has to be the body you want to put the face on. The second picture has to be of the face. Keep in mind these two pictures should relate in some way....Example...If the head in the Picture A is looking left , then the head in picture B should be looking left. This is because you dont want the face your photoshopping to look out of proportion and such...obviously. So what your gonna wanna do is this..I will be calling The Body picture PIC A and the Face Picture Pic B.

1. On pic B (face pic) Extract the face you want by going to filter and then extract. After you have circled the face with the green pen..and filled it with blue you can now click finish or done. ***Its okay to have a little extra in this pic..you can erase some of it later.
2. After you extract the face it will save it as a new layer...drag that layer into the body picture and you will have to then resize it and place it over the existing face.
3. After resizing and any warping/transforming that needs to be done, take the eraser tool and erase any extra from the face layer.
4. Your face now may be a couple shades too dark or a bit too much contrast so go to image>adjustments> Brightness/contrast and tweak the levers until you get what you want.
5. If step 4 left you still unhappy you can mess with the color balance too until you get what you want.
6. After youve made all your last minute mods and tweaks...you can merge all visible layers and your pic is complete.

That is the simple steps to it...Of course if your just doing it for fun those are the only ones you need to know....if you really wanna make it look authentic and real..your gonna have to spend a little bit of time messing with drop shadows and inner shadows and stuff and even maybe have to render some lighting effects..Practice Makes perfect..and before you know it, you'll be making pictures like this one of Megan Fox I made.
