Learn about changing the time of day by color grading with Boris color correction tools.
- [Instructor] Previously I discussed how to change the time of day, or apparent time of day, in a shot by applying Boris Light Effects. You do something similar by applying color correction, or color grading effects. This would be a good place to see how some of the Boris Color Effects work. Let's give that a try. I'm going to go back and get my jogger footage. And this is included also in chapter two. And I'll make a composition. Alright so this is definitely day time, strong blueish white light, distinct shadows, maybe late afternoon.
But we can try to change this to something else for example, perhaps sunset or even night time. Let's give it a try. Alright, while the layer is selected, I'll get the first color effect. Effect: Color & Tone, 3 Way Color Grade. This effect includes three color wheels that adjust the gamma, which is the contrast function, the lift, which effects the low end, and gain, which effects the entire range. There's also an exposure and saturation set of sliders.
You can move the cross-hair in each one of these wheels to bias that function towards a particular color. So, it's a way to tint. For example, if I click somewhere over here in this wheel, next to orange for gamma, it tints the entire scene orange. And you can do something similar with lift and gain. But maybe not to such a high degree. So that's very orange. You can also adjust the exposure.
Let's say I lower the exposure to make it darker. And if I want to increase or decrease saturation. I'd leave that at zero now. So maybe this is not as good as shooting the scene at sunset, for example, the shadows are very, very strong. But it's a way to bias something towards a particular color or to evoke a particular mood, like late in the day. So how do we create night time? Well, we can do something similar, but use some different effects. We're going to duplicate this layer upwards.
So: Edit, Duplicate. On this top layer, I am going to get rid of my old color grade, and get a new effect. Color & Tone, and this time Colorize. Colorize offers another way to tint something. Like you have more control, in terms of what colors. The way it works is, there's a gradient that runs from black to white. And at the start, that's why the image is black and white. But uou can turn on other colors to insert in that gradient.
Now, initially you do have Color 3 on. Color 3 is kind of a purple-ish color. I can turn that off and get true black and white there. But if I want to, I can turn on any combination of Color 2, 3, 4, and 5 and insert additional colors into that gradient. So darker parts of the image get the darker part of the gradient, brighter parts of the image get the brighter part of the image. And mid tones get the mid tones. And you can change what colors are inserted. So I'm going to turn on Color 2. Red is inserted right in the middle of the gradient, so that's why all of the mid tones are red.
Let's change it though, let me make that deep blue. So now it's very, very blue. And blue is often associated with night time. Now it's very intense, but I have another trick I want to use to blend this with the prior version. So that's OK. Now if I want to, I can turn on these other colors, but I just want it to be mostly blue right now. Now one problem is, the highlights are still very bright. You know, it must be a very bright moon. The sidewalk is really bright, her shirt, and the pavement.
You can work on that though, by adding another color effect. I also probably want to adjust the overall saturation, so let's do this: Effect, Color & Tone, and I'll use the Boris Hue-Set-Lightness effect, and reduce the saturation. Now I'm going to run to one of my personal favorite effects that comes with After Effects, and that's not a Boris effect, but it's a really good one, and that is: Color Correction, Curves.
What I'll do with the Curves effect is lower the bright end. Drop that side of the curve down so the brights get darker. You can also insert an additional point in that curve, and say pull it down to darken the mid tones further. Once I have all these effects, I might want to go back and forth and adjust them to balance them out. For example, maybe my saturation is too low. Or maybe I can adjust the original color I'm using in the tint.
Or continue to fine tune my curve on my curves effect. Now it terms of blending this with the original so it's not quite so strong, there's a couple of choices. One is Mix with Original, and many of the Boris effects have this. You can adjust this so it blends that effect with the unaltered version. So it's looking too strong, raise Mix with Original.
Another trick is to simply adjust the layer opacity. I can pull it down below a hundred, and blend it with what's below it. And what's below is still the version that has the sunset grade, but it's an opportunity to get an interesting set of colors. Now if I didn't like the orange, I can always go back and turn off the 3 Way Color Grade or alter the properties. Alright so here is a night time version. It's a little bit desaturated, it's a little bit blue, and it's not quite so bright.
So it could be either early evening or perhaps an evening with a relatively strong moon. So here are a few Boris Color Effects you can use for time of day change, and you can see how they work with standard effects, like the Curves effect, to work together.
VFX expert Lee Lanier begins by exploring shared Boris Continuum controls, and then shows how to apply stylistic effects. He explains how to work with the PixelChooser and Boris Lights, and discusses how to color grade and warp footage. He also takes you through using the Boris Chroma Key Studio and working with Mocha Pro for motion tracking, as well as how to add particles and work with 3D text.
