You'll want to learn -

1: How to select objects

Once you got a technique down (pen tool is the best, lasso will work fine too), you'll want to select around the head and cut off the head at either The Neck or The Shirt. You want to cut at a place that would be LESS obvious/easiest to cover up. Personally id go with the lower neck.

Next: You'll have to find a picture w/ roughly the same proportions as the orig. A childs head pasted on the worlds tallest man....well doesnt work too well.

2: How to color correct.

You'll want to color correct the head.....so it matches roughly the lighting/skin tones of the body. Levels, hue/saturation, curves, colorbalance.....anyone of those will help.

3: How to retouch.

When the colors/proportions match.....move the head (make sure its on a new layer and you have deleted, ctrl-x or masked out the orig head) into place. Depending on where you cut, use the clone tool to paint over any seams/missing areas and to blend the 2 areas (body & head) together.

Next: Select the area you retouched (use the lasso for this....it doesnt have to be perfect....the worse your selection....the better :D ) then go to Select>Feather and feather your selection about ~10 pixels (depending on how big this "area" is). Now with the feathered selection.......go to Filters and Add Noise. A small amount of noise give a more realistic look as the clone tool tends to blur the picture a bit, and noise will sharpen it up.

Hope that helps.

Yeah, Rodder's got it all pretty much covered but he forgot to mention that the pictures you choose to use are the most important thing. 2 pictures with the exact same head position would be perfect but are mostly hard to find unless you use a pic of yourself ofcourse. The transform tool will help you out alot with the ability to rotate and rescale the head image in a very precise way, but sometimes 2 images just won't fit together and you'll have to be doing alot of searching before you get what you want.

I also prefer cutting the head at the border of the shirt your person is wearing and have the longest neck possible. Then use the healing brush or clone stamp tool to completely (or partially if you choose to) remove the original head from the image, so you wont have all kind of weird "objects" sticking out of your new head when you are done. Now put the new head on your pic, rescale and rotate using CTRL+T and place it right, with the neck overlapping the original person's clothes (Shirt border). Now select along the border of the shirt and remove that part from the head image. The neck will now fit nicely and you are getting where you want to be.

Use selective color (put it on reds) to adjust the heads skincolor. Also adding noise and shadows might be necessary to get the most realistic effect.

Here is an example I did. Don't ask . It's not a 100% but I think it looks okay enough. Mind that I did not use the neck of the new head, its not always necessary and in this case even impossible, cause the new head originally has a very thin neck, making things much harder. If you have got some questions left please ask.

man, thats awesome... thanks .. i will try to pick up the tips u guys gave me .. and if i come up with problems, can i message u guys ?
