This project was done by photographing a miniature replica of the plane, masking it, and sizing it appropriately to the environment. This meant that the perspective of the background image had to be the same as the plane's. The present boxes also had to be in line with the image's perspective, which was achieved through scale and positioning. Lastly, the Santa sleigh, a 3D file, simply mimicked the plane's perspective in 3D space.
Additional details that sold the effect can be seen through out the image: the revolving door underneath the plane, Christmas lights on the wings created with layer styles, moonlight highlights on the present boxes, the moon itself, and a silhouette of Santa in the sleigh. The overall image was given a blurring effect to add depth.
