Imagenomic Portraiture 4.5 — macOS

Portraiture 4 for Mac (build 4501) updates the AI smoothing engine to a next-generation version. That means less time spent on pixel-level cleanup and more time on the actual portrait.

One Realistic Task, Start to Finish

Say you have a headshot with uneven skin tones and some blemishes. Instead of hand-masking every patch, Portraiture does the heavy lifting.

• Open the plugin — It runs inside Photoshop, Lightroom Classic, or Affinity Photo. You select the area you want to work on.
• Let the AI find the skin — The plugin detects skin tones and creates a mask automatically. No manual selective masking needed.
• Adjust the smoothing — You control the strength, and the preview updates in real time. If the AI overreaches, you can dial it back or paint the mask yourself.
• Finish and export — The plugin applies the effect as a layer or mask, so you can tweak it later if needed.

That’s the whole job. The manual masking you used to dread is gone, and the result looks natural because you’re the one deciding how much smoothing to apply.

A Portrait Photographer’s Workflow With Portraiture

Think about the day after a family photo session. You have forty raw files to get through, and half of them are kids with scraped knees and uneven complexions. Before Portraiture, you’d open each image in Photoshop, zoom in, and spend three to five minutes carefully painting a mask around each face, dodging hair and eyes, then applying a surface blur or frequency separation. That adds up to hours of repetitive work.

With Portraiture 4, you load the first headshot, let the AI smoothing engine find the skin, and adjust the mask only where the AI got confused — maybe a stray hair or a reflective eyeglass lens. You apply the effect as a layer mask, then move to the next image. The second file takes maybe a minute. By the thirtieth file, you’re done in a fraction of the time it used to take, and the results are consistent across the whole set because you used the same smoothing strength and mask refinement for every face.

What Changed in Build 4501

The current release, build 4501, is built around a next-generation AI smoothing engine. In everyday use, that means a few noticeable differences:

• Better edge detection — The plugin is less likely to blur the boundary between skin and hair. The mask cleaner on the first pass, so you spend less time painting corrections.
• Finer texture preservation — Skin pores and natural texture stay visible at moderate smoothing levels. The old engine sometimes turned everything into plastic; this one holds onto more detail.
• Improved handling of tricky lighting — Side-lit faces or shadows across the nose no longer confuse the mask as often. The AI seems to read the luminance gradient better.

Nothing else in the interface changed. The same controls, the same real-time preview, the same layer and mask output options. If you already knew how to use Portraiture 3, you will not need to relearn anything.

Two skin retouching plugins that handle the job differently

Portraiture is not the only skin retouching plugin for Mac photographers. Two other tools come up often, and each handles the job differently.

Portraiture vs. Beauty Box

Beauty Box works as a Photoshop plugin too, and it also detects skin and applies smoothing. Its approach is simpler — fewer controls, less fine-tuning. You pick a preset, and it runs. That can be fast for batch work, but you lose the ability to adjust the mask or the smoothing strength per image. Portraiture gives you more control per portrait, which matters when you have a mix of ages and skin types in one session.

Portraiture vs. Delicious Retouch for Lightroom

Delicious Retouch is a Lightroom preset collection, not a plugin. It applies a look to the whole image, then relies on Lightroom’s brush to paint over skin areas. It works well for a consistent style, but you have to do the masking yourself. Portraiture automates that masking step entirely. If you shoot hundreds of portraits a month and want to keep the skin work separate from the overall color grade, Portraiture saves more time.

Neither Beauty Box nor Delicious Retouch has the same next-generation AI smoothing engine that build 4501 introduced. For a photographer who wants the AI to handle the mask and then layer the effect non-destructively, Portraiture is the most flexible option.

Fixing Portraiture when it doesn't appear in Photoshop's Filters menu

• The plugin doesn’t appear in Photoshop’s Filters menu — This usually means the installer placed Portraiture in the wrong plug-ins folder. Check that the .plugin or .8bi file is in Photoshop/Plug-Ins or Adobe Photoshop [version]/Plug-Ins. On Apple Silicon Macs, make sure you installed the correct build for your architecture.
• The mask misses part of the face — Portraiture’s AI scans for skin-toned pixels. If the subject has heavy makeup, a beard, or unusual lighting, the mask can leave gaps. Use the plugin’s manual brush to add the missing area, or lower the detection threshold in the settings panel.
• Smoothing looks too strong even at low settings — This sometimes happens with very high-resolution files (50 megapixels and up). Try reducing the image size before running the plugin, or apply the effect as a separate layer and reduce the opacity later.
• The installer won’t run on macOS — The Gatekeeper warning appears because the plugin is not digitally signed by Apple. Follow the standard workaround: mount the disk image, run Open Gatekeeper friendly, press Enter in the Terminal window, then proceed with the installer. This is a one-time step per install.
• Lightroom Classic doesn’t see the plugin — Portraiture ships separate downloads for Photoshop and Lightroom Classic. If you installed the Photoshop version, Lightroom won’t see it. Make sure you download the correct build for your host app.

Creating a baseline setting from one test portrait

1. Test on one file first — Pick a portrait with normal lighting and minimal facial hair. Run the plugin, adjust the smoothing to what looks natural to you, and note the settings you used. That becomes your baseline for the next session.
2. Use the layer mask output — When you apply Portraiture, choose the option that creates a new layer with a mask. That way you can paint out any over-smoothing on the eyes, lips, or hair without re-running the plugin.
3. Try different smoothing strengths on the same face — Run Portraiture at 20, 40, and 60 percent on the same portrait. Compare the three results side by side. You will learn how far you can push the AI before it starts to look artificial.
4. Keep a before-and-after copy — Duplicate the background layer before applying the plugin. If you change your mind about the strength later, you can re-run the plugin on the original layer instead of undoing a stack of edits.
5. Watch the edges around glasses — The AI sometimes blurs the frames or the glass itself. After the mask is applied, use a black brush on the layer mask to restore the sharp edges of the glasses. That takes about ten seconds per pair of frames.
6. Group your files by skin type — If you are processing a wedding or a family session, sort the portraits by age or skin texture first. Apply the same settings to similar faces, then adjust only the outliers. This batch approach speeds up the whole workflow.
