Type "a beautiful portrait" into any of these tools and you'll get something generic. Type the right prompt into the right tool and you'll get a magazine cover. Most guides stop at the prompt. The part nobody tells you is that the same prompt gives you three different results in Midjourney, Flux, and Nano Banana — and picking the wrong tool for the shot wastes more time than a weak prompt does.

So this is the head-to-head. What each model is genuinely best at, how to write for it, and the prompts to copy. No hype, just where each one wins.

Which AI tool makes the best portraits?

There's no single winner — it depends on the shot. Midjourney wins on pure aesthetic and mood; it makes the most beautiful, stylised, editorial images with the least effort. Flux wins on realism and people; it renders believable skin, hands, and natural light, and it follows detailed instructions closely. Nano Banana (Google's Gemini image model) wins on control and consistency; it's the one for editing an existing photo, keeping the same face across shots, and getting text or specific layouts right. Choose by the job: beauty and style, pick Midjourney; photoreal humans, pick Flux; edits and consistency, pick Nano Banana.

That paragraph is the whole answer. The rest is how to actually get it out of each one.

What every great portrait prompt contains

Before the tool differences, the fundamentals — because a great prompt in the wrong tool still beats a lazy prompt in the right one. The good prompts specify these, woven into natural language rather than listed:

Subject plus one human detail — not "a woman," but who, doing what, with one specific, human detail (a slight smile, wind in the hair, mid-laugh).

Lighting — the single biggest lever in the whole prompt. "Soft directional window light" and "hard studio rim light" produce completely different photos of the same person.

Lens and framing — "85mm, shallow depth of field" reads like a portrait; "24mm wide" reads like a snapshot. Naming a lens does real work.

Styling and wardrobe — outfit, fabric, era, mood. "Deep-emerald silk saree" carries more than "traditional clothing."

Colour and grade — a palette or a film-stock reference (Portra 400, teal-and-orange, muted editorial).

Atmosphere — haze, particles, grain, texture in the air. This is what makes it feel shot, not rendered.

And skip the empty buzzwords — "masterpiece, 4k, ultra-realistic, trending on artstation" do almost nothing. Specifics do everything.

The same idea, levelled up

Generic: portrait of a woman in traditional clothing

Dialled in: A cinematic portrait of a woman in a deep-emerald silk saree, seated by a tall window in soft directional morning light, 85mm lens with shallow depth of field, warm editorial colour grade, fine film grain, a quiet and regal mood.

Same subject. Completely different result. Now here's how that prompt behaves across the three tools.

The head-to-head

Midjourney — the aesthete

Midjourney makes the prettiest image with the least work. Its default taste is strong, so even a short prompt looks styled and cinematic. The trade-off: it interprets rather than obeys. Ask for ten specific things and it'll give you a gorgeous image that honoured six of them. It's also the least literal with faces if you need a specific person.

Prompt it like this — lead with mood and let it run:

Cinematic editorial portrait of a woman in a deep-emerald silk saree, seated by a tall window, soft morning light, 85mm, shallow depth of field, warm film grade, quiet regal mood, fine grain --ar 4:5 --style raw

The --style raw pulls it toward photography over illustration; --ar 4:5 is the Instagram portrait crop. Best for: editorial, fashion, moody and stylised looks where beauty matters more than exact accuracy.

Flux — the realist

Flux is the one that makes people look like people. Skin texture, hands, teeth, natural light — the things other models botch, Flux handles. It also follows a detailed prompt more faithfully, so all those specifics you wrote actually land. The trade-off: its default aesthetic is plainer, so you have to direct the beauty rather than getting it for free.

Prompt it like this — be explicit and literal, it rewards detail:

Photorealistic portrait of a woman, mid-20s, wearing a deep-emerald silk saree with visible fabric texture, natural skin with subtle pores, seated beside a large window with soft directional morning light from camera-left, shot on 85mm f/1.8, shallow depth of field, muted editorial colour grade, subtle film grain

Notice the physical detail — "visible fabric texture," "subtle pores," light direction. Flux uses all of it. Best for: realistic humans, headshots, product-on-model, anything that has to pass as a real photo.

Nano Banana — the controller

Nano Banana (Gemini's image model) is the one for control. It's built for editing — hand it a real photo and say "change the background to a studio, keep her face and outfit exactly," and it holds consistency the others can't. It keeps the same character across multiple images, handles text in-image, and respects layout instructions. The trade-off: for a from-scratch beauty shot, Midjourney usually looks better.

Prompt it like this — describe the edit or the consistency you need:

Using this photo, place the subject beside a tall window with soft morning light, keep her face and the emerald silk saree exactly as they are, add a warm editorial colour grade and shallow depth of field, photoreal

The power move is "keep X exactly" — that's the whole reason to use it. Best for: editing existing photos, consistent characters across a set, on-brand shoots where the face or product must stay identical.

Quick verdict

Tool Best at Weak spot Reach for it when Matching prompts
Midjourney Aesthetic, mood, editorial style Ignores some specifics; literal faces You want the most beautiful image, fast Cinematic Portrait prompts
Flux Photoreal skin, hands, prompt accuracy Plainer default look It has to pass as a real photo Studio & Professional Portraits
Nano Banana Editing, consistency, text/layout Weaker at from-scratch beauty shots You're editing or keeping a face/product identical Product Photography prompts

How to choose in one line

If you're starting from nothing and want it to look stunning, Midjourney. If it has to look like a real human photograph, Flux. If you're editing a real image or need the same face across a whole set, Nano Banana. Most serious creators use all three — Midjourney or Flux to generate, Nano Banana to fix and keep consistent.

Where to get prompts that already work

You don't have to write every prompt from scratch. PromptThisOne is a hand-curated library of AI image prompts tested to produce real results, with the example output shown so you see what you're getting before you copy — and each is tagged with the models it works best on.

The most-used sets: Cinematic Portraits for editorial and moody looks, Bridal & Wedding Portraits — the ones the community reaches for most, Saree & Ethnic Portraits for traditional and editorial looks, and the full AI image prompt library.

Find the look you want, copy the prompt, run it in the tool that matches the job above, swap in your details. The recipe's already written.
