ADD GLOW TO THE CAR
In reality, any specular or highlight reflection
has some glow in it. In order to make this glow on
the car, duplicate the Specular and Reflection passes
by selecting them from the Layers panel, then go to
Layer>Duplicate Layer and press OK. Release them
from the clipping mask by going to Layer>Release
Clipping Mask, then drag them from the Layers10
ADD THE LIGHT BURST TO THE
HEADLIGHTS
You can paint with a bright colour on the headlight to
create an optical flare, or you can just use the one that I
made provided on FileSilo. Drag and drop the light
burst file onto the scene and make sure that you put it
on the top of the stacking order by going to Layer>
Arrange>Bring to Front, then scale it and position it on
the car headlights. Duplicate it to the other one by Opt/
Alt-clicking and change its blend mode to Add using
the drop-down in the Layers panel.09
DARKEN JUST THE WHEELS
Show the RGB layer mask from the Layers
panel, then go to the Channels panel and Cmd/
Ctrl-click on the green channel. Then hide the RGB
mask again and create an Exposure adjustment
layer right underneath the Occlusion layer and lower
the Gamma value to 0.8002001 Prepare the background

Use the RGB mask to easily make adjustments to certain areas of the image
002 Import the passes
Combine the render passes in Photoshop and change the blend mode to Add
panel just underneath the Occlusion Shadow
layer. Some of the layers will be out of the
clipping mask, so you have to bring them back
in again. Merge the duplicated layers by
selecting them in the Layers panel and go to
Layer>Merge Layers, blur them using
Filter>Blur>Gaussian Blur at 3 pixels, then
change the blend mode to Add.
CREATIVE LIGHTING EFFECTS
The render passes are very
important. They give you a
great amount of control after
the rendering process, especially
if you work in 32bit
