After Effects: Adding Lighting Effects in Post demonstrates how to use virtually any version of After Effects to easily add animated lighting effects to existing footage. Going beyond basic techniques, Chris Meyer shares his personal experience and uses many examples to teach the best way to select and fine-tune lighting clips to enhance a variety of underlying shots. He presents techniques for subtle enhancements that will help hold the viewer's attention while adding production value to virtually any shot. Chris also discusses how to create lighting clips from scratch, either with a camera or by using Fractal Noise.
Sometimes you need just to completely invert your lighting footage. Now in this case, on my original footage has this woman, set it in the frame, dark details run outside and I'll play through her for now. Again it's a nice scene but quite frankly, I think that the values on her face are too close to that of the bookcase. I would like her to punch out more. I would like to brighten her. I would like to darken her surroundings. This is the technique known as vignetting, where you fall off from light in the middle to darker in the outside of the frame.
I've chosen my potential lighting layer something that has a little bit of vignetting orientation. The values around the outside are different than the values in the center. The problem is that the center is dark and the outside is bright and in this case I want the opposite effect. Just put this in Overlay for now to see what's going on. It darkens her face even more, brightens and tints the bookcase, not the desired effect. That's very simple. Just invert the layer. I'll select my lighting layer and apply Effect > Channel > Invert. Now you will notice that she has gone bright and the outside has gotten dark. I've put the emphasis back on her face. Let's look at that original footage inverted.
Not only has it inverted my brightness values, which where it's dark around here, brighter in the middle, it's also inverted the color, which happens to complement her skin tones better than the blue did. Go back to Overlay, you'll see the Effects pretty nice on her face. Let's say this is a little bit orange in tone. Simple enough. Effect > Color Correction > Hue/Saturation again and again bend the Hue of my lighting layer to get a little bit more of a yellowish flesh tone which is more like what I like. That's too strong. I'll put it in Soft Light mode. That's a bit more subtle.
Before and after. Really warmed her up, really made her pop by using a vignetting effect. But to do that, first I had to invert my source footage. So it's a matter of reacting to what lighting layers you have and bending them to your needs.
