Compositing an Image

This is the plane that I have had to composite onto the other image, in order to do this I jad to first select the whole plane to be copied onto the other half of the compostion. In order to do this I used the magic wand tool to select the white background, however this only selected the white whereas I needed the plane so I inverted the selection so that instead of having the plane as the only thing not selected it was the thing that I had selected. The only problem with this was that some parts of the plane had not been completely selected and some parts of the background where still selected, in order to select and deselect the parts i needed I used the polygonal lasso in order to get a straight refined edge to my selection.
So that I didn't have a "halo" around the edge of my picture I had to feather the image by 0.5 pixels. This then meant that I could easily copy and paste this plane into the other half of my composition.

To make the plane look more as if it hasn't been photoshopped into this image I needed to resive it and keep the proportions constrained, I needed to resize the plane down to about 75% of it's original size. To make the plane look as if it is turning I rotated anti-clockwise this gave the effect that it was turning away from the camera. The only problem with this picture now is that it doesn't look as if it is moving as there is no motion blur in order to change this I went into filters->blur->motion blur, I then needed to make sure the angle on the blur is the same as the angle that the plane is flying in, then made the distance for the blur abour 15 pixels. However when something is moving the leading edge doesn't blur so that is why I made this on a copied layer of the composited image so that I could delete the leading edge this made the plane look like it was moving and made it look very realistic.
