Skin tones fall apart when edits get heavy-handed or flat. If you want portraits that look editorial and true to life, you need control over tone and color that goes deeper than HSL sliders.
Coming to you from Gerard Needham, this practical video walks through a three-step method using Lightroom’s RGB curves to shape skin tone without touching HSL at all. Needham starts by stripping things back. No complex color mixes. No endless slider tweaks. He builds the edit on a tonal foundation in the Basic panel, either compressing the range for a matte film look or expanding midtones for a cleaner editorial style. When you lower contrast, ease highlights, and manage blacks carefully, you give skin more room to breathe. That wider midtone range creates smoother transitions from highlight to shadow, which changes how skin color rolls across the face.
He shows how contrast actually squeezes or stretches midtones rather than simply making an image pop. When you see it on a grayscale example, the shift becomes obvious. Expanding midtones softens transitions. Increasing contrast narrows that space and makes tonal shifts more abrupt. If skin looks harsh or uneven, this is often why. Getting this step right means the later color work behaves predictably instead of fighting against uneven tone.
Next, Needham sets a color base before touching the curve. He sticks with the Adobe Color profile and tweaks the Calibration panel instead of leaning on HSL. Red primary shifts slightly toward orange for warmth. Green primary moves away from yellow to reduce that sickly cast that can creep into skin. Blue saturation drops just enough to remove the cold edge that digital files often carry. These are small adjustments, but they shape the starting palette in a way that feels more cohesive than isolating individual hues later.
Then the RGB curves take over. Needham builds a simple S-curve in the master channel to reintroduce contrast after flattening the midtones earlier. From there, he copies the curve into the red, green, and blue channels to neutralize color shifts and reset the baseline. Once equalized, he begins subtle channel-specific moves. Add red to midtones and pull blue down slightly and skin picks up a golden glow. Lift green carefully and you warm things further, but go too far and the undertones turn muddy. Drop green slightly and magenta comes forward. Every move affects the light itself, not just a color range.
He also demonstrates a popular warm highlight and cool shadow split using small moves in each channel. Teal in the shadows. Warmer reds in the highlights. A slight magenta bias in bright areas for a film-inspired look. The key is anchoring points so adjustments don’t bleed across the tonal range. Even the black and white points can be tinted for subtle separation.
There’s more in the video, including how the same curve adapts across different skin tones and lighting conditions with minor exposure and white balance tweaks, plus a deeper breakdown of why equal RGB changes equal white. Check out the video above for the full rundown from Needham.
