Get Imagenomic Portraiture 4.5 Build 4501 for Mac

You’ve nailed the exposure and the expression is perfect, but the subject is self-conscious about a patch of dry skin that morning coffee couldn’t fix. The usual fix means zooming in to 300%, drawing precise masks, and painting adjustments pixel by pixel until your eyes cross. Portraiture 4 for Mac steps in right at that moment, handling the selective smoothing so you can get back to the rest of the edit.

AI finds skin without manual masking

• Automated skin masking. The AI engine identifies skin tones and textures on its own, removing the need to manually paint a mask before you even touch a slider.
• Preserving natural texture. It targets fine blemishes and uneven patches while leaving eyebrows, eyelashes, and the sharpness of the eyes and lips alone.
• Working across hosts. Separate builds are available for Adobe Photoshop and Lightroom Classic, both running natively on Apple Silicon and Intel Macs.

Plugin-only tool needs a host app

• It is a plugin, not a standalone editor—you’ll need a host application installed to run it.
• Requires macOS 13 or later.

Mistakes I see newcomers make

When a plugin automates the heavy lifting, it is easy to let the defaults do all the talking. The most common slip is cranking the overall strength slider to eighty or ninety percent and calling it done. That leaves faces looking like wax sculptures—pores vanish, cheekbones soften into dough, and the portrait loses the very texture that makes it feel human. Pull it back and lean on the Opacity control instead. A value around forty to fifty percent often gets you closer, and you can always mask the result lightly in Photoshop afterward.

Another mistake is skipping the mask preview. Portraiture shows you exactly which pixels it is affecting, but plenty of folks never toggle that view. When you see the mask, you might notice it bleeding into a shirt collar or catching the edge of a dark background. A quick pass with the include/exclude eyedroppers clears that right up. Beginners also tend to ignore the Fine, Medium, and Rough granularity controls under the advanced panel. The default often bumps the medium slider harder than necessary; dialing it back while raising the fine detail preservation can rescue the tiny skin texture that makes a portrait breathe.

The last one is treating it like a standalone app. I have watched people close Photoshop the moment the plugin dialog opens, as if it were running on its own. It is not. The host is still doing the heavy lifting behind the scenes, and closing it mid-session is a recipe for a lost edit and a frustrated sigh.

Lightroom-to-Photoshop handoff workflow

Portraiture for Mac sits squarely inside Photoshop or Lightroom Classic, but it plays well with other tools once you know where the handoffs happen. A common setup in my circle is this: cull and color-grade in Lightroom, send a TIFF over to Photoshop for cleanup, and fire up Portraiture on a duplicated layer. That layer stack is what makes the whole thing sing—you keep the untouched original at the bottom, a frequency separation pass above it if you need texture work, and the Portraiture result on top with an opacity slider and a black mask. Paint the effect in only where you want it, like the forehead and cheeks, and leave the nose tip and jawline crisp.

On the macOS side, the plugin leans into a few system-level niceties. Because both builds run native on Apple Silicon, the Neural Engine gets tapped for the AI masking calculations. That means the fans stay quiet on an M-series MacBook Air even when you are processing a high-megapixel file. You can also drag images directly from a Finder window or an Apple Photos export into your host, run the plugin, and save back out—no extra import round-trip. If you use Affinity Photo, the Imagenomic site lists official compatibility, and I have seen it load as a standard Photoshop-format plugin there without much fuss. The key is pointing Affinity’s plugin search path to the same folder where the Photoshop version lives.

Near-instant masking on Apple Silicon

Running build 4501 on an M1 or M2 machine feels quick in a way that earlier versions did not. Opening the plugin on a 24-megapixel RAW file takes about a second, and the mask preview updates in near real time as you drag the sliders. I have pushed it through batches of thirty headshots from a single session without a crash, which says plenty about stability on macOS 13 and above. There is a brief processing pause when you switch to the output tab and ask it to render the full-resolution result, but that is the AI engine working at final quality—it is not a hang.

Memory use sits around 300 to 500 MB while the plugin dialog is open, plus whatever Photoshop already needed. If you are stacking multiple heavy layers, the system can feel the weight, but Portraiture itself is not the culprit. On older Intel Macs, the mask calculation takes a noticeable extra beat; still usable, just not the instant feedback you get on Apple Silicon. I have not seen it trip over macOS Gatekeeper once the initial installation is handled, and it has played nicely with every Photoshop point update I have thrown at it this year.

Workflow: a portrait clean-up from import to export

Say you have a natural-light portrait shot in front of a bright window. The skin looks a little ruddy, there is a stray hair across the cheek, and the under-eye area needs softening without losing the catchlights. Here is a path that works reliably.

Start in Lightroom Classic. Apply a gentle tone curve to lift the midtones, set white balance, and enable lens corrections. Do not touch the skin sliders yet—skip the Texture and Clarity panel entirely, because Portraiture will handle the fine detail in a more targeted way. Export the image as a 16-bit TIFF in ProPhoto RGB and open it in Photoshop.

In Photoshop, duplicate the background layer twice. Name the middle layer Cleanup and the top one Portraiture. On the Cleanup layer, use the Spot Healing Brush to remove the stray hair and any obvious transient blemishes. Keep it light; this is about objects, not texture.

Now select the Portraiture layer and launch the plugin. Toggle the mask view on so you see the black-and-white overlay. Use the skin-picker eyedropper to sample three points on the forehead, cheeks, and chin—that teaches the AI which tones to target. In the advanced panel, set the Fine slider to around +15 to keep pore structure, drop Medium to about −10 so the broader unevenness gets smoothed, and leave Rough near zero. Set overall strength to 55 percent. The mask should hug the skin and avoid the eyes, hair, and clothing; if it picks up the collar, swap to the exclude eyedropper and click the offending area.

Apply the result. Back in Photoshop, drop the Portraiture layer’s opacity to around 70 percent and add a layer mask filled with black. Grab a soft white brush at 30 percent flow and paint the effect onto the cheeks, forehead, and under-eye hollows. Leave the nose bridge, lip line, and eye contours unpainted. That keeps the face dimensional and avoids the plastic flatness that over-application brings.

Finish with a curves adjustment for contrast, sharpen for output, and save. The whole sequence takes under four minutes once you know the rhythm, and the result looks like careful manual retouching, not a one-click filter.

Missing from Filter menu after install

One of the first things people hit is the plugin not showing up in the Photoshop Filter menu after installation. This almost always comes down to the installer placing the file in the wrong plugin folder, especially on Macs where multiple Photoshop versions coexist. Check /Applications/Adobe Photoshop [version]/Plug-ins/ and make sure the ImagenomicPortraiture.plugin file is sitting inside. If you run both Photoshop and Lightroom, remember that Imagenomic provides separate downloads—the Lightroom version will not appear in Photoshop and vice versa. Grab the right one and the menu entry appears straight away.

Another snag is banding in the mask preview, where the black-and-white overlay shows harsh edges instead of a smooth gradient across skin tones. That usually means the image has a heavy JPEG compression or a low bit depth. Switch to a 16-bit working space before launching the plugin, and the mask engine gets more tonal information to work with. The result is a cleaner, more gradual transition.

Some people notice that the plugin’s dialog window opens at a tiny size on high-resolution displays. That is a scaling quirk in certain macOS versions. You can resize it by dragging the corner, and the new dimensions stick for the next session. If the sliders feel sluggish, check that Photoshop is not running under Rosetta—Portraiture runs natively on ARM, and forcing the whole host into emulation mode drags everything down.

Occasionally, the AI smoothing engine applies a slight color shift, warming the skin a touch as it evens out textures. When that happens, I drop a Hue/Saturation adjustment layer above the Portraiture layer and clip it so it only affects the plugin result. A tiny nudge to the reds or yellows brings the color back in line without undoing the smoothing work.

Build 4501 brings a next-generation version of the AI smoothing engine.
