Step 12: Creating the Light Housing
Make a new layer and move it to the top spot in the Layers palette. Name this layer "light_housing.”
At the very top of this layer, use the Rectangular Marquee tool (M) to make a selection that’s 500px wide by 10px high. Change the foreground color in the Tools palette to #17150e and fill the selection with this color by pressing Alt+Backspace.
Duplicate the "lip” layer by selecting it in the Layers palette and pressing Command +J. Move this new layer above the "light_housing” layer in the Layers palette and rename it "housing_highlight.”
Use the Move tool (V) to move the layer up so that its bottom is in the same position as the bottom of the "light_housing.”
Press Command + T to transform the layer. Adjust it from the top so that it’s roughly half its current height.
Step 13: Adding a Shadow Beneath the Light Housing
Select the "housing_highlight” layer in the Layers palette and press Command + J to duplicate it. Rename the layer "housing_shadow” and invert it by pressing Command +I.
Flip the layer vertically by going to Edit > Transform > Flip Vertical. Then, nudge it down 1px by pressing the Down Arrow once.
Finally, change its opacity to 80%.
Step 14: Creating a Light
Launch IES Generator. At the bottom left of the application window, click the Load button and locate the "1589835-nice.IES” profile that you downloaded in the Tutorial Preparation.
Using the sliders at the lower left of the window, adjust Brightness to 1.11 and Away From Wall to 3.00 so that the image on the right side of the window looks something like this:
Step 15: Bringing the Light into Photoshop
IES Generator doesn’t have an export or save function, so a screen capture is needed to paste it into the Photoshop layout. You can use a screen capture utility if you have one. Otherwise, press Alt + Print Screen (this is a Windows key-combination which captures the active window to the clipboard). After making the capture, return to Photoshop.
Open the "textures.psd” document created in Step 1, if it isn’t already open. Press Command +V to paste the screen capture into the document. It will appear in a new layer above the "corkboard” layer. If for some reason it ends up below the "corkboard” layer, just move it up in the Layers palette.
With the new layer selected, use the Rectangular Marquee tool (M) to make a selection around the IES image as shown:
Go to Select > Inverse to invert the selection. Fill this region with black.
Step 15: Extracting the White Pixels from the Light Layer and Positioning It
Now we’ll use the free AlphaWorks plug-in by Cybia to remove all the black from this layer, so that we end up with just the white pixels that make up the light pattern.
Go to Filter > Cybia > AlphaWorks. From the drop down menu at the upper right of the filter’s dialog box, select "LINEAR BlackOut – remove from BW lineart.” Click OK.
This will be the result:
With this layer still selected, press Command +A (Select > All), copy it, then switch to the "main_layout.psd”.
Select the "Hue/Saturation 1″ layer in the Layers palette and press Command +V to paste. The new layer will appear between the "lip” layer and the "Hue/Saturation 1″ layer. Rename it to "ies_light.”
Nudge the "ies_light” layer up 6px by pressing the Up Arrow six times. Now change this layer’s blending mode to Overlay.
