Как генерировать фотореалистичные изображения с Krea 2

Фотореалистичный кадр ломается в деталях: plastic skin, мёртвые материалы, missing shadow falloff или shallow focal stack, который не ощущается сфотографированным. Чистая composition alone не спасает. Эта страница — photoreal workflow spoke. Определение продукта и speed tiers — на what Krea 2 is. Порядок wording — в prompt guide. Здесь unique job — subject-class tactics, material review и refinement loop, который выдерживает full-size QA.

Photoreal frame — изображение, которое по-прежнему читается как shot или art-directed при zoom и material logic checks. Material review — pass, который проверяет light, texture, edges и reflections до accept keeper.

Такой one-purpose split следует helpful content guidance Google.

Ключевые выводы

• Выберите один subject class до writing the brief: portrait, product, environment или lifestyle.
• Light и material language бьют длинные «ultra realistic» adjective stacks.
• Review at full size и reduced size; photoreal может fail в любом view.
• Итерируйте one variable at a time, обычно light или angle first.
• Package art всё равно требует poster, cover или quote checks после lock photoreal plate.
• Hub — для tiers; prompt guide — для stack order.

Что «photoreal with Krea 2» значит на практике

Review signal	Pass condition	Common fail
Light logic	Source, direction и falloff согласованы	Flat beauty fill with no motive
Material	Surface roughness и reflection match object	Wax skin, chrome matte plastics
Edge detail	Contours clean under zoom	Soft mush or aliased edges
Depth	Foreground to background separation optical	Everything equally sharp
Crop honesty	Frame still works in real publish ratio	Pretty 16:9 forced into 1:1

Системы «текст в изображение» быстро улучшили surface fidelity, а control и evaluation fine structure остаются hard (Zhang et al., arXiv 2025; Croitoru et al., diffusion survey). Поэтому photoreal work — review process, а не one lucky generation.

Step 1: выберите subject class до любых style words

Разные photoreal jobs нуждаются в разных success tests:

• Portrait / character: skin, eyes, hair edges, catchlights
• Product / still life: material accuracy, reflection control, clean silhouette
• Environment / concept: scale cues, atmospheric layers, light paths
• Editorial / lifestyle: people plus place, readable gesture and context

Сначала pick one class. Смешивать «hero product + cinematic crowd scene + magazine cover» в один промпт обычно даёт average everything.

Step 2: соберите photoreal brief из light и material

Используйте prompt-stack order из prompt guide, затем specialize fields for realism:

1. subject noun
2. material or wardrobe truth
3. place and time of day
4. light source and quality
5. lens and depth cues
6. crop for the first channel

Portrait recipe

Close-up portrait of a woman by a window, soft directional daylight, 85mm lens look, shallow depth of field, natural skin texture, calm expression, 3:4

Product recipe

Studio product shot of a matte ceramic mug on dark stone, single softbox key, controlled reflection on rim only, crisp focus, minimal background, 1:1

Environment recipe

Misty mountain pass at dawn, volumetric light through layered haze, wet rock texture in foreground, wide establishing camera, painterly realism, 16:9

Избегайте padding «8k, ultra detailed, masterpiece». Предпочитайте measurable optical и material cues.

Step 3: generate directions, not infinite noise

Photoreal quality приходит из short branch, не из eternal re-rolling.

Practical batch plan:

1. two light directions
2. two angles
3. one crop family only
4. keep two candidates max before refinement

Supported crops всё ещё важны: 1:1 для product tiles и avatars, 3:4 для portraits, 16:9 для cinematic environments, 9:16 для vertical stories. Ratio families в production и print workflows — в практических references (poster size chart; print aspect ratios guide).

Для explore-stabilize-finalize economics используйте shared map на product hub. Не relearn tier lectures здесь.

Step 4: full-size material review

Используйте этот метод тестирования, прежде чем назвать кадр photoreal:

1. Откройте at 100% и inspect skin или surface microstructure.
2. Проверьте, существует ли light source, implied by highlights, в scene.
3. Проследите reflection behavior на metal, ceramic, glass или wet stone.
4. Confirm hair, fabric или object edges не smear into halos.
5. Reduce to thumbnail size и verify silhouette и focal subject still hold.
6. Compare against job class: portrait eyes, product logo plane, environment scale cue.

Если image выглядит real только как small card — это social thumbnail, не photoreal master.

Step 5: refine winner one variable

Отправьте best candidate назад как reference. Меняйте only one of these at a time:

• light quality or direction
• camera height or lens feel
• material roughness
• palette temperature
• background calm vs activity

Common repairs:

Symptom	Likely cause	One-variable repair
Plastic face	Beauty light and over-smooth skin	Softer contrast + pore texture language
Dead product	No key motivation	Add single softbox or window key
Fake environment	Missing atmosphere layers	Add volumetric depth and scale cue
Correct mood, wrong crop	Style locked first	Rebuild in the real publish ratio

Artifact patterns — over-smooth skin, broken reflections, smeared microdetail — всё ещё появляются; practical artifact writeups вроде ZSky artifacts guide помогают назвать, что вы видите в review.

Subject-class playbooks

Portrait playbook

• prioritize catchlights и eyelid structure over background drama
• prefer 85mm или three-quarter feel for faces
• keep wardrobe materials concrete: linen, leather, wool
• reject wax skin даже когда pose perfect

Product playbook

• decide matte vs gloss before style words
• control reflections; do not ask for "shiny" without direction
• keep background quieter than the hero silhouette
• check logo plane или label plane, если branding will sit there later

Environment / concept playbook

• include one scale cue: figure, vehicle, doorway, rock ledge
• define weather and light path through volume
• hold a simple palette so atmosphere stays readable
• review mid-ground separation, not only the hero prop

Lifestyle / editorial playbook

• show gesture and context, not a floating mannequin
• choose time-of-day light that matches the story
• keep one focal action; secondary props should not compete

Campaign hierarchy thinking помогает после lock photoreal plate: dominant motif, readable contrast, intentional empty areas (movie poster anatomy overview). Если plate станет packaging или social type — hand off к poster, cover или quote guides.

Production checklist и rights note

Перед publish или client handoff:

• subject class matches the job brief
• light logic passes at 100% zoom
• materials pass roughness and reflection checks
• crop matches the first channel
• winner refined with one-variable references
• commercial use reviewed against plan terms on pricing
• remaining rights or account questions can go through contact

Считайте AI photoreal output сильным production plate. Final retouch, legal review и brand marks всё ещё живут в design toolchain.

Common failure modes и fixes

Failure	Cause	Fix
"Looks AI" at full size	Texture and light never specified	Rewrite material and light fields
Great small, fake large	No full-size review	Always inspect at 100%
Endless re-rolls	Changing everything each pass	Reference lock; change one field
Pretty plate fails package	Photoreal only, no type mass	Apply packaging spoke rules next
Wrong tool expectations	Need novelty spam, not realism	Use the comparison guide

FAQ

Достаточно ли слова «photorealistic» как prompt word?

Нет. Модели нужны subject, material, light и lens cues. Само слово — preference, не setup.

Начинать с portraits или products?

Начинайте с subject, который нужно ship first. Portrait work stresses skin and eyes. Product work stresses reflection and silhouette. Они учат разным reviews.

Сколько variations генерировать?

Достаточно, чтобы cover two light и two angle options внутри one crop family. Больше обычно burns budget без better decisions.

Чем это отличается от prompt guide?

Эта страница владеет photoreal subject workflows и material review. Prompt guide владеет wording order и general control language.

Где fit speed tiers?

В explore-stabilize-finalize path на product hub. Эта страница остаётся на photoreal QA и refinement.

Bottom line

Генерация фотореалистичных изображений с Krea 2 — directed production loop:

2. write light-and-material briefs
3. generate a short branch of directions
4. review materials at full size
5. refine one variable at a time
6. hand off package art to the matching use-case guide
