The exact sliders, in order, to give any set of images a consistent, cohesive look.
A consistent look is what separates a portfolio from a camera roll, and in Lightroom it comes down to a short, repeatable sequence. Start in the Basic panel: set white balance first, then recover highlights and lift shadows until the histogram breathes, and only then touch exposure. Fixing tone before color keeps you from chasing a grade that fights the underlying brightness.
Next, move to the HSL panel and pull the luminance of skin-tone oranges up slightly to make people glow, then desaturate the blues and greens a touch so the frame does not compete with your subject. Finish in Color Grading by warming the highlights and cooling the shadows just a few points each — this split-tone is the heart of the cinematic look people ask about. Save the result as a preset, then sync it across the shoot and fine-tune each frame rather than grading from scratch.
Drop in your own before-and-after frames and the preset values you landed on. A grade is personal, so treat these numbers as a starting point and adjust to your taste.
