The first step as usual is make preliminary tonal adjustments.
Now, we get to the key part to create the Cinematic effect using the split tone. As mentioned, I select a warm color to brighten up her face and a teal color for the shadows in the background. I also shifted the balance towards the shadow to bring out more of the teal tint.
Next, I revisit the tone adjustment panel to enhance the contrast. In this photo, I find that only adjustment in the Blackest is good enough. I also lower clarity to give her skin a softer look.
For the final touch, I added a vignette to put her face in focus.
