There are many ways to make the aluminum on aircraft to pop in a photograph. Pretty much anytime light hits bare metal it makes the metal turn a different color. The shadows and highlights can define every edge of a plane. With bare metal one of the amazing ways to show off the surface is too use a strong highlight in the background. It’s one of the times that a bright white background actually works well.
