Portrait retouching is one of the most technically involved areas of digital photography post-processing. Done well, it produces images that look natural and polished simultaneously — skin appears smooth without looking plastic, tones are balanced without looking manipulated, and the subject looks like themselves rather than an approximation. Done poorly, it produces the opposite. The key is a structured workflow that applies corrections in the right order and at the right level of strength.

This walkthrough covers a two-stage workflow: global and local adjustments in Lightroom Classic, followed by detailed skin retouching in Photoshop. Both applications use the same underlying RAW processing engine (Adobe Camera Raw), which means moving between them is lossless — all adjustments are stored as instructions applied to the original RAW file.

Stage 1: Global adjustments in Lightroom

The first stage handles exposure, colour balance, and global tone corrections. These adjustments affect the entire image and establish the foundation that everything else builds on. Making these correctly before moving to Photoshop reduces the amount of work required in the pixel editing stage.

Exposure and white balance

Start with the histogram. Adjust exposure so the tonal distribution sits where you want it — generally, most information should fall in the mid-tones, with highlights not clipped unless the light source is in the frame. In portraits, skin tones typically fall around the right-centre of the histogram.

White balance sets the overall colour temperature. For portraits, a slightly warm white balance (around 5500–6000K) tends to be more flattering to skin tones than a neutral or cool balance. Adjust the tint slider if the image has a green or magenta cast — common with mixed lighting or fluorescent sources.

Tone curve

The tone curve gives finer control over tonal relationships than the basic sliders. For portraits, a gentle S-curve — slightly boosting the upper-midtones and slightly reducing the lower-midtones — adds a sense of contrast without affecting the extremes. Adding a small lift to the shadows (bringing the bottom-left point of the curve slightly upward) is common in commercial portrait work, creating a softer, slightly matte feel.

HSL adjustments

The Hue/Saturation/Luminance panel lets you modify individual colour ranges independently. For portrait work, the orange and yellow ranges are most relevant — skin tones across most complexions fall within these hues. Reducing the saturation slightly in the orange range can calm overly vivid skin, while increasing the luminance in that range can brighten it without changing colour. Be conservative: changes of 5–15 points are usually sufficient.

Spot removal for obvious blemishes

Lightroom's Heal tool handles small blemishes efficiently. At this stage, remove only the most obvious temporary imperfections — active breakouts, visible dust on the lens, sensor spots. Leave more nuanced skin texture correction for Photoshop, where you have significantly more control over what gets changed and what remains.

Stage 2: Detailed retouching in Photoshop

Once the global adjustments are complete in Lightroom, right-click the image and choose "Edit in Photoshop" to open it as a smart object or a flattened TIFF, depending on your preference. Working non-destructively — using layers and layer masks throughout — allows adjustments to be undone or modified at any point without starting over.

Frequency separation

Frequency separation is a retouching technique that splits an image into two components: the high-frequency layer (fine texture — pores, individual hairs, skin detail) and the low-frequency layer (colour and tone gradients). By separating them, you can adjust colour and tone without disturbing texture, and vice versa.

To set it up manually: duplicate the background layer twice. Name the lower copy "Low Frequency" and the upper copy "High Frequency." On the Low Frequency layer, apply a Gaussian blur of 4–6 pixels — enough to eliminate texture while keeping broad colour gradients visible. On the High Frequency layer, go to Image → Apply Image and set the Source to the Low Frequency layer with Blending set to Subtract, Scale to 2, and Offset to 128. Change the blend mode of the High Frequency layer to Linear Light. The two layers together should match the original.

The Gaussian blur radius for frequency separation depends on the resolution of the image and how finely the skin detail is captured. At 24 megapixels from a typical full-frame camera at normal portrait shooting distances, a radius between 4 and 7 pixels typically gives a useful separation.

Work on the Low Frequency layer with the Clone Stamp tool (set to Current Layer, with a large soft brush at low opacity) or the Patch tool to even out uneven colour — redness around the nose, shadows under eyes, or a colour cast across part of the face caused by a strong light source. The High Frequency layer preserves all the pore and skin detail, so these corrections affect only tone and colour.

Dodge and burn

Dodge and burn is the process of selectively lightening and darkening areas of an image to shape the way light falls on the subject. In portrait retouching, it is used to sculpt facial features — strengthening the highlights on the bridge of the nose, the forehead, and the cheekbones, and deepening the shadows in hollows of the cheeks, under the jaw, and around the eye sockets.

The non-destructive method: create a new layer filled with 50% grey (RGB 128,128,128) and set its blend mode to Soft Light. On this layer, paint with white at low opacity (5–10%) to lighten, and with black at the same opacity to darken. At Soft Light blend mode, 50% grey is invisible, so only the deviations from grey affect the image beneath.

Work at low opacity and build gradually. Use a large, soft brush for broad light shaping across the face, and a smaller brush for fine detail — removing small shadows caused by skin texture, emphasising a highlight in the eye. Zooming out regularly and comparing the retouched layer to the original by toggling visibility is essential — it is easy to over-work at high zoom levels.

Eyes and teeth

Eyes in portraits benefit from specific attention. A Curves adjustment layer — brightening the luminosity slightly in the iris — can make eyes appear more present without making them look artificially lit. Add the adjustment on a separate layer with a mask that confines it to the iris. For the whites of the eyes, a similar Curves layer restricted to the sclera can remove slight yellowing. Be very conservative here — overtly white eyes draw attention to themselves.

For teeth, a Hue/Saturation adjustment layer restricted to the teeth area, reducing the yellow hue and slightly desaturating, is the standard approach. Lightening should be minimal — teeth appear naturally off-white rather than pure white, and any edit that makes them look whiter than the whites of the eyes reads as unnatural.

Skin tone consistency

One of the most common errors in portrait retouching is focusing on isolated areas at high magnification without regularly checking the full image. Skin tones should be consistent across the face — the forehead, nose, cheeks, and chin should read as the same complexion under the same light. If they do not, it indicates uneven retouching. A Hue/Saturation layer or a selective colour adjustment restricted by a mask can address colour inconsistencies that remain after the frequency separation work.

Colour grading and output

Colour grading in portrait work is typically subtle — the goal is to create a consistent mood across a set of images rather than a dramatic transformation of individual shots. Lightroom's Colour Grading panel (or a Colour Lookup Table applied as a Photoshop adjustment layer) can add a slight warm cast to highlights and a cooler tint to shadows, creating depth. The Camera Raw filter in Photoshop gives access to all Lightroom controls as a Photoshop filter, applicable to a Smart Object layer.

For output, export as JPEG at quality 85–90 for web delivery, or as a 16-bit TIFF for print. Colour space depends on the intended use: sRGB for web and consumer printing, Adobe RGB or ProPhoto RGB for professional print workflows where the output device has a wider gamut.

Adobe's Lightroom Classic help documentation covers the healing and cloning tools in detail. Phlearn's frequency separation walkthrough provides video-based guidance on the technique. For calibration reference, the X-Rite ColorChecker Passport is a widely used tool for consistent colour across a shoot.

A structured retouching workflow — global adjustments first, detailed work second, regular comparison to the original throughout — produces results that are both technically correct and visually convincing. The tools are secondary to the method.
