Advanced Photo Editing in Lightroom Classic: Local Adjustments & Range Masking

Editing One Part of a Photo Without Touching the Rest

In the last part of this series we began the editing process with the Develop module’s global sliders — adjustments that apply to the whole frame at once. Those will carry most photographs a long way. But they can’t answer the question every real edit eventually raises: what if you only want to change this part?

That’s local editing, and Lightroom Classic has a genuinely good set of tools for it — the Crop tool, Spot Removal, the Graduated Filter, the Radial Filter, the Adjustment Brush, and Range Masking to keep them all honest. In this tutorial we’ll walk through each one, then use them together to deepen a flat sky and pull attention onto the subject.

Global Edits Versus Local Edits

A global edit moves the entire image. Raise Exposure and every pixel gets brighter; cool the Temp slider and the whole frame goes blue. That’s exactly what you want for overall correction, and it’s why the basic panel comes first.

A local edit is confined to an area you define. Darken only the sky. Sharpen only the face. Warm only the foreground. Nothing else in the frame moves. Every tool in this tutorial works the same way underneath: first select a region, then apply the same familiar sliders to just that region. Once that clicks, all of them feel like one tool with different selection shapes.

Cropping and Straightening

Cropping in Lightroom is completely non-destructive — you can reopen the crop at any point, even months later, and recover the full original frame.

1. Press R for the Crop tool

   Drag the handles to reframe. Press Enter to commit — and remember the History panel will still take you back.

2. Lock an aspect ratio if you need one

   The ratio menu at the top of the panel includes 1:1, which is the fastest way to prepare a square crop for social before you export.

3. Straighten the horizon

   Either drag the Angle slider by eye, or pick up the Straighten tool and simply draw a line along the horizon in the photo. Lightroom rotates the frame so that line becomes level.

Removing Spots and Distractions

Spot Removal handles sensor dust, blemishes and small unwanted objects. Every repair creates a pin with its own sample point, and every one stays editable forever.

Heal versus Clone

Heal copies texture from the sample area and blends its tone and color into the surroundings. Clone makes a straight copy with no blending at all. Start with Heal. It’s right most of the time. Switch to Clone when you’re working near a hard edge — a horizon, a shoreline — where Heal’s blending smears one side into the other. In the example, healing worked on open sand but the tracks running up to the waterline needed Clone, so the sky wasn’t dragged down into the beach.

1. Zoom to 100%

   Retouching judged at fit-to-screen always looks better than it is.

2. Size the brush with the bracket keys

   Open and close bracket shrink and grow the brush, exactly as in Photoshop.

3. Paint over what you want gone

   Lightroom picks a sample area automatically and usually chooses well.

4. Move the sample point if the result is wrong

   Drag the second circle anywhere in the frame. This is the whole skill — finding a source patch with the right texture and enough clean room in it.

5. Work in short passes

   Several small repairs beat one enormous stroke, and each stays individually adjustable.

Toggle the tool off and compare to the before — on a beach frame, simplifying the sand rather than erasing every mark completely is what keeps it looking like a photograph.

Red-Eye Correction

Less common than it used to be, now that few people shoot with an on-camera flash close to the lens, but it’s a single click when you need it: select the tool and drag across the eye. Lightroom finds the pupil and neutralizes it.

The Graduated Filter

The Graduated Filter applies an adjustment that fades linearly across the frame — strongest at one end, invisible at the other. It is the digital equivalent of a glass ND grad, and it is the natural tool for skies.

1. Turn a slider down before you draw

   Drop Exposure first so you can actually see the gradient as you place it. Nothing appears to happen otherwise.

2. Click and drag across the image

   Drag from the top down for a sky, or from any edge inward.

3. Rotate and reposition freely

   Grab the center line to move the whole gradient; grab an outer line to rotate it. It stays live indefinitely.

4. Now set the actual adjustment

   Reset Exposure and build the effect properly: cool the Temp for a bluer sky, nudge Tint toward green, raise Saturation, then bring Exposure down a little for depth.

The Radial Filter

Same idea, different shape: the Radial Filter confines the adjustment to an ellipse. Draw it, then drag the handles to make it wider or taller, or rotate it to any angle.

Two controls matter more than the rest. Invert flips whether the adjustment lands inside the ellipse or everywhere outside it, and you can switch it at any time. And Feather goes up: Aaron generally brings it all the way to 100. A low feather gives a hard-edged oval that reads instantly as an edit; at 100 the transition disappears.

Every slider from the basic panel is available here — exposure, highlights, shadows, texture, clarity, saturation, sharpness, noise — plus a color tint you can push into the selected area.

The Adjustment Brush

When the area you want isn’t a line or an ellipse, you paint it by hand.

1. Set brush size with the bracket keys

   Same shortcut as everywhere else in the Adobe world.

2. Raise Feather for a soft edge

   This controls how quickly the effect falls off at the edge of the stroke. Higher is more forgiving.

3. Lower Flow for subtlety

   Flow sets how much of the adjustment each pass lays down. A low flow lets you build the effect gradually across several strokes, which is far easier to control than one heavy pass.

4. Paint, then adjust

   Brush the region, then move the sliders. The two are independent, so you can keep refining the look long after the mask is painted.

Painted masks can be repositioned as a whole, and deleted with the Delete key at any point.

Range Masking: The Part That Makes It Look Real

Here’s the problem every local edit runs into. A Graduated Filter pulled down over a sky also darkens anything standing up into it — a tree, a rooftop, a mountain ridge. The edit is right for the sky and wrong for everything in front of it.

Range Mask is the fix, and it’s the most valuable thing in this tutorial. At the bottom of any local adjustment panel it starts at Off; switch it to Color or Luminance and the adjustment is further restricted to only the tones or colors you nominate.

1. Set Range Mask to Color

   An eyedropper appears beneath it.

2. Click the color you want to keep affecting

   Click the blue of the sky. The adjustment instantly stops applying to the tree, because the tree isn’t blue.

3. Widen the sample if you need to

   Click and drag with the eyedropper to sample a range of blues rather than a single one — skies are rarely one flat color.

4. Soften the mask with the Amount slider

   Push it too far and the separation gets crunchy and obvious. Back it off until the edge between sky and tree looks natural.

Luminance mode does the same job using brightness instead of hue, which is often the better choice when the thing you’re protecting is a similar color to its surroundings but a different tone.

Putting It Together: Deepen a Sky, Lift a Subject

Here is the full edit on the beach photo from the series sample images, Intro to Lightroom-10 — a flat sky, a scattering of tire tracks across the sand, and a subject sitting too dark to hold your eye.

1. Straighten and crop

   Draw along the horizon with the Straighten tool, then trim the frame.

2. Clear the ground

   Heal the loose marks in the open sand, then switch to Clone for the tracks running toward the waterline so the edge stays clean.

3. Grade the sky with a Graduated Filter

   Drag from the top down. Cool the Temp, nudge Tint toward green, raise Saturation, and lower Exposure slightly for depth.

4. Protect the tree with a Range Mask

   Set Range Mask to Color and sample the blue. The tree returns to its original tone while the sky keeps the grade.

5. Brush light onto the subject

   Adjustment Brush, high feather, low flow. Paint over the subject and a generous margin around her — painting a tight silhouette is what makes local edits look cut out.

6. Set the subject sliders

   Raise Exposure a little, lift Shadows, and add a touch of Texture, Clarity and Sharpness. The eye goes to the brightest, sharpest thing in the frame, which is exactly the point.

Compare the before and after and the logic is clear: the ground stopped competing for attention, the sky gained color and depth, and the subject became the brightest point in the image. None of those three changes was possible with a global slider.

Where This Usually Goes Wrong

Sampling from too small an area

Spot Removal needs somewhere clean to copy from. If your source patch is barely bigger than the repair, the result repeats visibly. Give it room, or make several smaller repairs from different sources.

Leaving Feather low

A hard-edged radial or brush mask is the single most obvious tell of a local edit. Push Feather up until you can’t find the boundary.

Painting a tight outline around the subject

Brushing exactly to the edges produces a cut-out glow. Paint loosely and past the subject; the falloff does the work.

Pushing the Range Mask too hard

Narrow the color range far enough and the separation goes crunchy and artificial. Widen the sample and soften the Amount slider until it reads naturally.

Forgetting these tools stack

You can run several Graduated Filters, Radial Filters and brushes on one photo, each with its own Range Mask. Reach for a second pin rather than overloading one.

Take It to Your Own Photos

Local editing is where an image stops being corrected and starts being directed. Every one of these tools is doing the same two things — choose an area, then move sliders — so the skill worth practicing isn’t the tools at all. It’s noticing which part of a photograph is fighting the part you actually want people to look at.

Open a photo you’ve already edited globally and ask one question: what’s competing with my subject? Then darken it, soften it, or simply take it out.
