Lighting Effects
Learning how to use the built-in lighting
effects filter is one of the most important skills you'll
ever learn for Photoshop. It allows you to add volume and
reality to normal 2D objects. Here we go:
|
|

|

|
Start by opening Photoshop and creating a new image. For
this example, I chose dimensions of 200x200 pixels. Make a selection.
Anything will do, you can use text (like I did) or make a square
or ellipse. After you have a selection, fill it with a solid color.
(If you used text, it should already be filled).
|

|

|
Go to the Layers palette. Rename the layer with your filled
object "Base" by right-clicking it and selecting Layer Options.
Hold down Ctrl and click on the Base layer to load
it as a selection. Switch to the Channels palette and create a new
channel by clicking .
|

|

|
Hit Alt/Backspace to fill your selection with white.
Next go Filter>Blur>Gaussian Blur and choose a radius
of 12 pixels (with a bigger/smaller image you will need a bigger/smaller
radius). Then Gaussian Blur it again at half the radius you used
before (i.e. 6). Now lets get rid of those jaggies that form on
the outside of the selection. Hit Ctrl/Shift/I to invert
your selection and hit delete.
|

|

|
Go back to the Layers palette and click on Base to
select the layer again. Now hold Ctrl and click Base
to load your original selection. Then go to Filter>Render>Lighting
Effects... If an alert pops up asking you to rendering the layer,
click OK. Now the Lighting Effects window will pop up and give you
many options that you can play around with. First change the Texture
Channel to Alpha 1. Now it's up to you to pick options that
suit what effect you want. If you want to add more lights, click
the light bulb button. By clicking the image to the left, you can
see what options I used.
|

|

|
You could stop now if you want, but we can always improve,
right. Lets add a drop shadow to make it look a little more realistic.
Go to the Layers palette and right-click the Base layer and
choose Effects. I used the default drop shadow and blue outer glow
with a blur of 10 pixels.
|

|

|
For a more plastic-like look hold Ctrl and click
on Base in the Layers palette to load the selection. Go to
Filter>Artistic>Plastic Wrap... I used the following
settings: Highlight 4, Detail 15, Smoothness 10.
|

|

|
This last step will allow you to play with the range of
colors used in your image. Hit Ctrl/M to bring up the Curves
window. Try clicking and dragging the line around to produce a nice
effect. You can click the image to the left to see what I did. I
also added a gray radial gradient to color in the background on
a layer beneath the Base.
