Hey Fablers, welcome back to another Academy tutorial. So here we've got the Tritone effect, is what we're going to be looking at in this episode.
With our usual canvas, we've got a single JPEG image. Let's select our layer, go to the top right to our effects window and let's type in tritone. Click, drag, and drop.
Super cool. Now, the way tritone works, is that it basically looks at three parts of your image. Hence the tri tone. You've got your highlights, your mid-tones and your shadows. Tritone lets you assign different color values based on the luminance of your image underneath between your darkest darks and your whitest whites.
In this case you can see here that the highlights have been turned orange, the mid-tones have been turned pink. The shadows have been turned blue.
Another way that you can see this a little bit more easily is if we take a hue and saturation and apply that above our tritone. Let's turn this off for a second.
Let's make our image black and white. This will better explain the topic. So here, we've got three tones. We've got highlights, mid-tones which is gray, and shadows, which is black. Now if we turn on the tritone, you'll see what happens.
There's a very marginal difference if you have this on or off, but just so that you can all see exactly what it's doing.
Colored image has a grayscale value, but if you have trouble envisioning it, grab a hue and saturation, de-saturate your image completely so it's in black and white, and then apply the tritone.
Basically these three options, you can choose any color you'd like. Let's go with a green or I guess it's a teal. The midtones, we can make it orange and let's make the shadows red. And now we're ready for an island party.
You can use the alpha channel. This checkbox won't affect it right now, but if your image has an alpha channel, it will use this checkbox to respect or not respect the transparency in your layer. And lastly, we've got our global opacity, which turns down the intensity of our effect.
