How to Effectively Use the Tone Curve in Lightroom 2022

Within Lightroom, the tone curve functionality grants you the ability to precisely adjust the shadows, midtones, and highlights in your photograph through specific point modifications. Moreover, this feature enables you to modify colors to attain the specific look you’re aiming for. We’re going to guide you through the process we followed to edit an image using the tone curve.

What Is The Tone Curve?

The tone curve is a linear line that runs from the bottom left to the top right. The top point is your white point, and the bottom part serves as the black point.

People typically use the tone curve as an S-Curve. This involves adding a point in the shadow portion and another in the highlight portion of the curve—an S-shape form when they manipulate these two points to adjust their exposure.

If you’ve been working with images for a while, you’ll know that every pixel in your photo comprises Red, Green, and Blue (RGB). Each pixel is assigned a color value between 0 and 255.

  • 0 = no color
  • 255 = full color

The red, green, and blue channels represent the values of each color you have in your image.

The tone curve also serves as a visual representation of the color range of your image. The point curve represents the overall brightness.

You can increase or decrease the brightness by moving the curve up or down. You can add multiple points along the curve to get an acceptable range of control over the brightness and colors.

Where to Find the Tone Curve

  • Go to View > Edit Panels > Light

The tool will show up on the right panel of your screen.

You’ll see four hollow buttons above the curve line, plus a button with curves and another with a hollow X on the far right.

  • Gray – Edits the RGB channels
  • Red – Edits the Red channel
  • Green – Edits the Green channel
  • Blue – Edits the Blue channel
  • Curve – Edits the Parametric curve

Hollow X – A target adjustment lets you adjust the Tone Curve by dragging directly in the photo.

Editing the Tone Curve

We’ll start by clicking on the Target Adjustment button.

Hover your cursor over the image and notice how you see two circles appear. One is hollow, and the other contains a color fill. Move the cursor around and notice how the filling changes color depending on its position.

Step 1: Move your cursor to the lightest element in your image and double-click your mouse button. A point will automatically occur in the white point area of the curve.

Step 2: Move your cursor to the darkest element in your image and double click.

Step 3: Follow the same procedure for the mid-tones. Your curve should look something like this:

Step 4: Grab a point and drag it up or down. Notice the changes that occur in your image. If you like what you see, release the mouse button to select it.

TIP: Before you go any further, it’s a good idea to open your original image outside Lightroom and place it next to the app interface. That way, you can compare how the changes look as you adjust the curves.

While we liked how the curve adjustments added vibrancy to the buildings, we felt the sky was too bright. We intended to draw the viewer’s eye to the buildings.

To fix that, we clicked on the Red button and set the points so that the red curves lightened the sky and water, plus brightened the red buildings more.

Next, we clicked on the Blue button and followed the same procedure.
