1. Open After Effects and create a new composition apple n. NTSC DV Name it Volume Light and click ok.
2. Create a new solid. Apple y. Make it the comp size and a solid color of black and click ok.
3. In your timeline rename the new solid, “light source”. This will be what are light shines through to give us that underwater feeling.
4. To create the light source we are going to use fractal noise. With your light source layer selected in your timeline move over to your effects a presets panel and type in fractal noise and double click on it to place it on our solid. Or the effect can be found at Effect>Noise & Grain>Fractal Noise
5. Change the Parameters of the Fractal Noise Effect to the following
Fractal Type: Basic
Noise Type : Spline
Contrast: 500
Brightness: 0
Overflow: Wrap Back
Complexity: 2
Opacity:100
Blending Mode: Normal
6. We now need to make this layer 3d to place at the top of our composition as this is what our light shines through at the surface. In your timeline place a checkmark next to the 3d cube.
7. Select your lightsource layer and drag it to the top of your comp
8. With the lightsource layer selected in the timeline make it a 3d layer and hit r to bring up its rotation settings and change the orientation parameters
Orientation: 90.00” 0.0” 0.0”
Drag it back down into your comp if needed to see the light source layer in your comp at the top
9. Create a new adjustment layer. This will be used for our light. Layer>New>adjustment layer. In your timeline rename it to Light by selecting the layer and hitting enter/return
10. With this layer selected we are going to place the effect cc radial fast blur.
Effect>Blur&Sharpen>CC Radial Fast Blur
11. Change the effects under radial fast blur to the following
Center: 360,-54 (changes where the light will shine down from)
Amount: 95
Zoom: Brightest
12. We need to add another effect to our adjustment layer Light to accomplish our task. So place the effect Transform found at Effect>Distort>Transform
13. Under Transform in your Effect Controls change the following Parameters
Anchor Point: 360,240 (default)
Position: 360, 232
Uncheck Uniform Scale as we are gong to change the Scale Height
Scale Height: 158.4
Scale Width: 100
Use Composition’s Shutter should be check marked
14. In your timeline select your lighsource layer and type e to bring up effects for keying.
15. Under Fractal Noise twirl down to reach your Evolution Stopwatch setting. This is right under Sub Settings. Hold down Alt and click on the stopwatch for evolution. This will bring up our Expression option as we are going to animate the evolution with a simple math expression.
16. In your timeline an expression is written for you. This is not what we want so select it and hit delete. Next type in the following expression
time*50. Then click off of it and scrub through your timeline to see what it has done.
17. Now to try it out and make it look like underwater. Save your file if you have not already. Now create a new comp and call it final. Make the background a blue that is almost black.
18. In your new comp drag the precomposed volume light we made to the timeline. If you scrub through the timeline it should like you are underwater. You can tweak setting now to get that perfect look you want.
Add Bubbles
19. In your new composition “Final” create a new solid and name it bubbles. For color chose a light blue
20. Place this solid layer to the bottom layer in your timeline. With it still selected place the following effect on it. Effect>Simulation>CC Bubbles
21. Change these effects for the bubbles in Effects Controls
Bubble Amount: 12
Bubble Speed: 0.8
Wobble Amplitude: 10.5
Wobble Frequency: 1.6
Bubble Size: 1.2
Reflection Type: Liquid
Shading Type: Fade Inwards
22. Scrub through the timeline and it should look pretty cool.
