Now lets go over the "AUSTRAL" logo on the ailerons.
I have applied the mask with the letters removed (negative of the film) and shoot the whole area with Metalume
Notice an arrow in the upper right hand corner. This is the light direction.
I am going to paint the graphic to make it look like it's carved into the surface or "concave", This is ultra easy to do. All we do is paint black on the sides of the letters that would be in the shade if it actually was carved into the surface. In this case the right side of the letters.
What I then do is paint the other side of the letters in white.
After I pull the film, this is what we have.
