Understanding the Tone Curve in Lightroom

The tone curve is the most powerful tonal adjustment in Lightroom, and also the most intimidating. That wavy line on a graph scares people. But once you understand what it does, you’ll use it on every edit. What the Tone Curve Does The tone curve maps input brightness to output brightness. The horizontal axis represents the original tones in your image from dark (left) to light (right). The vertical axis represents the adjusted brightness from dark (bottom) to light (top).

The HSL Panel: The Most Powerful Tool in Lightroom

Most Lightroom users adjust exposure, contrast, and white balance, then jump straight to presets or export. They skip the HSL panel entirely — and they’re missing the most powerful color control tool in the entire application. HSL stands for Hue, Saturation, and Luminance. It lets you adjust individual color ranges independently, giving you precise control over how every color in your image looks. How HSL Works The HSL panel breaks your image into eight color channels: Red, Orange, Yellow, Green, Aqua, Blue, Purple, and Magenta.
