I see some guys are very found of neon light in their paintings. It is like an age of painting neon lights in the paintings, they are everywhere. I have tryed to paint them two but i didnt end upp with the same effect. I cant get that bright light right look on them. The light i paint look very flat and dead. Almost like a leak of blood instead of light source. Is there a secret that i'm missing or how do you guys do it? I have watched Ryan Churchs videos and he is using Painter to make that effect with the glow pencil, but why doesnt it look like it is glowing for me?
You mean neon light specifically, or the lighting environment that looks like neon light? It would help if you can include a picture as an example of what kind of effect you are trying to achieve.
Paint a line with a brush, take the glow brush, lower the value in the colour palette, paint over the line. Or, paint a line, make a new colour dodge layer, take an airbrush, paint over the line.
