So to be clear, you are cutting and pasting people from various photographs together? Or just their heads? Not sure I'm clear on how you did this.
It's sort of like cutting/pasting heads, but just a little more sophisticated.
First, I try to shoot so that the posing doesn't change much between frames. It's much harder to "put the puzzle together" if everything is different between images. Once the images are shot, then my workflow looks like this...
- Open all the images and paste them on top of each other creating a stack of multiple layers.
- Using the "eyeball icon" turn off the visibility of unwanted layers so you are only working with one layer at a time.
- Use the opacity slider on the top layer to set it at 50% opacity. You will be able to see both images at once.
- Move the top layer into position (control + click/drag) so that it lines up with the underlying layer. Think about where you want your seams to be. Zooming to 100% view helps you position it exactly.
- Set the opacity back to 100%.
- Add a layer mask to the top layer. (See the white box appear next to the layer, this is your layer mask)
- Invert the layer mask (Control + I). This will make the layer mask turn black and make the top layer "invisible".
- Use a paintbrush with a soft edge (Hardness = 0) and paint on the layer mask (make sure you've clicked on it to highlight it as the active area) using white to "paint in" the top layer image on top of the bottom layer. With a layer mask, painting with white will allow the top layer to show through and cover up the bottom layer. Anything that is black on the layer mask will block the top layer from appearing at all, and shades of gray will partially reveal the top. The quick memory tip is "White reveals, black conceals."
- If you make a mistake while painting on the layer mask, hit the "X" key to toggle between painting with white or painting with black. You can paint black over your error and then toggle back to white to paint it in again.
- I will usually start out with big brush strokes to get the main subject into the picture, then zoom in with smaller and smaller brushes to touch up the details so the overlap looks natural. Sometimes you need to "fade" the blend in with big soft brush strokes, and other times it needs to be a hard edge line with precise brush work.
- Toggle the top layer on and off (eyeball icon) to help you see where any overlap errors might be.
- Repeat the above process for the next image layer, until everyone is in the photo and looking how you want them to.
I made a little animated gif to show where the blends on my image were. The tricky spot was blending the transition between my leg and my son's hand to look natural, and blending my wife's shoulder/arm/sweater (basically a seam down the middle of her torso).
