How'd He Do That

Photoshop is a very powerful image editing program originally written for the Macintosh, but Adobe ported it over to the PC for the rest of you folks. So here is how I use it to combine two pictures. Keep in mind, I'm a hacker, and only just scratch the surface of this program.

Figure.1
Draw a rectangle around the area of interest in the first image and copy it. Open the second image and paste it in. The paste command will automatically create another layer in the second image, so I have the 'Background' layer and the new pasted section on layer_2, kind of floating above the Background. So the only thing I actually want from layer_2 is Sean. ( Second from the left, on the Honda ) The rest of that 'copied' piece is all just for positioning. None of it is going to be in the finial image.

Figure.2
On layer_2, use the 'Fill' transparency slider to lighten this layer in order to see through it to the Background layer.

Figure.3
Now zoom in and position it, by rotating it and scaling it to better match up with the Background. I drop in a couple of grid lines, to line the two up, and blink layer_2 on and off until I get the best placement.

Turn off the Background and then use the Eraser tool to rub out the parts of layer_2 that you don't want. Turning the Background on and off as you progress makes it easy to know where to brush out.

Brushing these two pictures together is fairly easy because they're almost the same pictures. Angle, subject, and lighting.

Figure.6 & 7
The brush size, the feather, or softness of the edge of the brush and the opacity of the brush it's self, is the trick to blending the two without being obvious. Decreasing the size of the brush however, increases the hardness of the edge. The trick is finding the sweet spot. I used a smaller brush on the helmet area than around the edges.

So that's how the four guys get in the same picture and have an extra boot in the foreground. So why not just get a tripod..? Come on... you don't take a lot of stuff with you to the top O' the world.
