| The Bulkhead ProjectHere's what we're going to create in this lesson.
 | 


| Here's the five elements we'll use to make it. | ||||
|  |  |  |  |  | 
| "fire.jpeg" 480x480, 49k. | "bulkheadbkg.gif" 180x180, 9k. | 45% Grey RGB=115,115,115 | 100% black RGB=0,0,0 | The Mask 332x96, 2k. | 


|  First, you need a 4 layer document in Photoshop. Make sure you're in RGB mode. 
 
  
 | 


 


|  OK, we're ready to go. Working on the Channels pallette, drag the Mask channel onto the dotted circle at the bottom. This loads that selection. Go back to the Layers pallette again, and delete that shape from the top 3 layers, (2,3, & 4). Now you can see the fire showing through the grey background.

|  Back to the layers pallette, and let's choose the top layer, #4. With nothing selected, go to the filters menu and select "lighting effects". When that fires up, (could take a few seconds), we're ready to go. I used 2 spotlights for this image. In the "styles" menu, choose "crossing". Click on the small white circle at the center of that ellipse, and move it to the side. This is one spotlight. The straight line is pointing towards the source of the light. Click on one of the outside dots, and turn the light so it's coming from your top left. Click on the other white dot, and now that spotlight is activated. We want to point this one from the bottom right, but we don't want it to shine white light. Unlike the real world, we can also shine darkness out of these spotlights. Cool, huh? Click on the white square in the "light type" window, and a color pallette will pop up. Let's choose a very dark purple, almost black. Say OK, and now we'll see how it looks. OK, let's make this thing 3D now. Go to the bottom menu, "texture channel", and select your blurred channel, it should be "channel 5". Select the check box, "white is high", and choose a height of about 16. Don't go overboard, that thumbnail drawing of what's going to happen is not super-accurate. If you have the height *too* high, you'll get some bizzare effects at the edges. Play with the settings in the "Properties" menu, the bottom two will control your brightness, "exposure" by just making things lighter or darker, and "ambience" by shing an overall light of the color in the square over the entire image. The top two settings, "Gloss" and "Material", will affect the final result the most. You can choose "shiny" and "plastic" at 100%, and your image will throw off a bright reflection, just like hard plastic.

|  All right! We're almost there! Looks pretty good, but no-way is it going to merge with that background now. We want this image to melt into that grey layer, that color "#737373" is the average of the background colors. Let's load the original, un-blurred channel now. Working on the top layer, let's go to the "select" menu, and choose "modify/enlarge". Enlarge it by 4 pixels. Now, in the same menu, select "feather" at a setting of 2 pixels. Same menu again, and choose "invert". Now we've selected everything outside are text. DELETE all this, and the grey layer underneath show through.
