Step-by-step: Discover how to illustrate and light up a neon sign
1 I create the silhouette of the sign on top of a brick wall. I don’t have to render all of the wall because the neon light only illuminates a small area. I grab a free texture from www.textures.com and then convert the lighting using Levels and Curves. I mount the neon light on a glass plate for added 2 visual interest. I Use Blending Options>Bevel and Emboss and Inner Glow to build it up in three dimensions. Then I blend them with a Soft Airbrush and add specular highlights using a Hard brush. 3 I then add the electrical hardware behind the neon sign: the rods that connect the tubes to the plate and thin wires on the tubes to secure it in place. The reflection of yellow neon signs is often reddish instead of yellow, such as the one on the glass.
