Car underglow effect

[K4rMa]

Read this first!:  The key to this tutorial is working with shadows.  The goal is to "undo" the shadow under the car and replace it with a neon glow.  You can choose any color you wish.  I chose green for my car.

 

We are going to take this Volvo and ghetto-ize it with some neon under glow.

 

 

The first step is to make a selection around the car in which the neon glow will occupy.  Follow the underside of the car closely.  The rest of the selection area doesn't matter because we will be erasing it later.

 

Tools used this step:

Poly Lasso

 

 

Create a new layer by going:

- Layer

  -New

      -Layer

 

Then fill the selected area with your desired neon color by using the paint bucket.

 

Tools used this step:

Paint Bucket

 

 

Your layer window should look similar to this:

 

 

Now we are going to use our eraser tool (using the airbrush/fade brush style, not the hard-edge).

 

Erase the outer portions of the neon and parts of the neon where the light wouldn't touch.  (ie: in front of the front wheel should be dark.  Think of the sun being underneath the car and envision where shadows would lie.)

 

Tools used this step:

Eraser

 

 

 

Now change the layer blending option to "overlay" on the layer that has the neon on it.

 

(Or you can just lower the opacity of the neon layer and call it quits here.  However I feel the overlay method achieves a more realistic effect in most photos.)

 

 

You'll notice the neon lost some of its strength  when you changed the layer blending mode to "overlay"  To add more beef to it, simply make a copy of that layer.

 

 

Now our Volvo is ready for some late-night California cruisin'!

 

 

TIPS:  - For added realism, create another layer and fill the entire thing with your neon color.  Change that layer blending mode to "overlay."  Then erase the top half of that layer and what falls over the car and the very outer edges of the canvas.  Then lower the opacity a pretty good amount.  This will create a bigger spread of the light around the car, but barely noticeable.  However, it will prove to be a little bit more realistic

It's like so much realistic, I cannot occupy if this is false or this neon is true!
