사진 한 장으로 캐릭터 시트 만들기 — 프롬프트 전문 공개

사진 한 장에서 얼굴 8각도 + 전신 4각도 캐릭터 시트를 뽑아, 그 시트를 이후 모든 컷의 참조로 씁니다. 이렇게 하면 같은 사람이 여러 컷·여러 편에 걸쳐 같은 얼굴로 나옵니다. 사용한 프롬프트 전문을 그대로 공개합니다.

왜 필요했나

원래 사람을 그리지 않던 채널을 「사람이 사는 장면」으로 바꾸면서, 같은 사람을 어떻게 유지할지가 곧바로 문제가 됐습니다. 시트 없이 복붙 블록과 시작 프레임만으로도 첫 편은 8컷 중 7컷이 통과했지만, 여러 편을 가로지르는 고정 인물이 필요해지면서 캐릭터 시트가 필요해졌습니다.

입력물 — 세 가지를 다 시험했다

입력	결과
사진 12장(정면·3/4·측면 좌우·정후면·부감·전신)	가장 안전 — 뒤통수가 실물과 같음
정면 스크린샷 한 장(456×566)	8각도 + 전신 4각도가 다 나옴
스티커풍 일러스트 한 장(1024×1024)	그림 스타일 그대로 12패널

핵심은 두 번째입니다. 처음에는 "참조가 한 각도뿐이면 못 한다"고 생각했지만 틀렸습니다. 뒤통수는 지어낸 것이지만 자연스럽고 쓸 만했습니다.

입력 전에 반드시 하는 것 — EXIF 회전

아이폰 세로 사진은 실제로는 가로로 저장되고 EXIF 플래그로 돌려서 보여줍니다. 그대로 넣으면 모델이 "누운 얼굴"로 읽고, 이건 프롬프트로 고칠 수 없습니다. 전처리 스크립트가 회전을 픽셀에 직접 구워야 합니다. 같은 스크립트가 여러 장을 한 장으로 묶어 "참조 1장"에 여러 각도를 담는 역할도 합니다 — 생성 도구가 참조를 1~3장만 받기 때문입니다.

실패 다섯 — 이게 이 글의 뼈대

① 참조에 없는 것은 지어낸다

가장 크고 가장 안 보이는 함정입니다. 얼굴 시트만 참조로 주고 전신 시트를 뽑았더니, 프롬프트에 "SAME CLOTHING as the reference"라고 썼는데도 바지가 차콜에서 네이비로, 신발이 검정에서 갈색으로 바뀌었습니다. 볼 옷이 없으면 "같은 옷"은 아무 뜻이 없습니다.

처방은 둘입니다. 전신 사진을 합쳐서 주거나, 옷을 글로 못 박는 것입니다.

② "no accessories"가 안경을 지운다

원래 프롬프트에 no accessories가 있었는데, 안경이 이 얼굴의 가장 강한 식별자인데도 지워질 뻔했습니다. Glasses are NOT an accessory here and must be kept if the reference has them.로 못박아야 합니다.

③ "135 degrees"만 쓰면 정후면으로 간다

1판에서는 4·8번 패널이 거의 170도가 되어 뒤통수만 보이고 안경다리만 겨우 보였습니다. MOSTLY the back of the head, with only a small sliver of the cheek … THIS IS NOT A FULL REAR VIEW.라고 말로 못박은 2판에서 살아났습니다.

④ 모델은 사람을 "정리"하려 든다

얼굴을 갸름하게, 젊게, 매끈하게 만드는 경향이 있어 DO NOT IMPROVE THE PERSON 절을 통째로 넣었습니다.

Do not slim or narrow the face. Do not sharpen the jaw. Do not smooth the skin.
Do not remove or thin facial hair. Do not remove grey or white hair.
Do not make the person look younger. Do not remove or change the glasses.
Keep every asymmetry, every line and every irregularity visible in the reference.

그런데 수염은 세 판 모두에서 옅어졌습니다. 시트로는 못 잡는다는 뜻입니다. 결론 — 못 잡는 것은 시트가 아니라 매 컷 프롬프트에서 강조해야 합니다.

⑤ 도구 함정 — --variants가 --out과 같이 안 먹는다

후보 비교 없이 한 장씩 뽑게 됐습니다. 후보 둘을 원하면 두 번 돌려야 합니다.

프롬프트 전문 — 실사판

얼굴 8각도(2행 4열)와 전신 4각도(1행 4열), 두 개가 한 쌍입니다.

A · 얼굴 시트 (8각도)

Create a character reference sheet (model sheet) of the EXACT SAME PERSON as in the attached reference image. Read that person's face, hair, glasses and clothing from the reference and reproduce them; do not invent a different person and do not blend in anyone else.

LAYOUT
One single 16:9 image divided into 2 rows x 4 columns = 8 equal panels, separated by thin white gutters.
Head-and-shoulders framing in every panel: the top of the head and the top of the shoulders are inside every panel.
THE SCALE IS IDENTICAL IN ALL 8 PANELS: the distance from the top of the head to the base of the neck is exactly the same in every panel, and the head is centred left-to-right in every panel.
THE EYE-LINE IS IDENTICAL IN ALL 8 PANELS: imagine one horizontal line across the whole image at the height of the eyes; in every panel where the eyes are visible they sit exactly on that line.

ANGLES — the head rotates, the camera never moves. The camera stays at eye level and never looks down from above or up from below.
Row 1, left to right:
(1) front, 0 degrees — both eyes visible, nose centred.
(2) three-quarter left, 45 degrees — the far eye is still visible, the far cheek is partly hidden.
(3) left profile, 90 degrees — exactly side on, one eye visible, the nose in outline against the background.
(4) rear three-quarter left, 135 degrees — MOSTLY the back of the head, with only a small sliver of the cheek, the eyelash line and the ear still visible. THIS IS NOT A FULL REAR VIEW.
Row 2, left to right:
(5) front, 0 degrees, chin slightly lowered, eyes still looking forward.
(6) three-quarter right, 45 degrees — the mirror of panel (2).
(7) right profile, 90 degrees — the mirror of panel (3).
(8) rear three-quarter right, 135 degrees — the mirror of panel (4). AGAIN, NOT A FULL REAR VIEW.

IDENTITY — READ ALL OF THIS FROM THE REFERENCE AND KEEP IT IDENTICAL IN ALL 8 PANELS
Same face shape and bone structure. Same eye shape and eye spacing. Same nose. Same lips. Same jawline and chin. Same ears.
Same skin tone and the same skin texture, including pores, uneven tone, lines and any blemishes.
Same apparent age.
Same hair: same colour including every grey or white strand, same length, same parting, same fringe, same hairline, same volume. In panels (3), (4), (7) and (8) the back of the head and the hairline at the nape are fully visible and have exactly the same shape in both rear panels.
IF the person in the reference wears glasses, they wear exactly those glasses — same shape, same rim thickness, same colour — in EVERY panel, including the rear panels, where the temple arm is visible passing over the ear.
IF the person in the reference has facial hair or stubble, keep it exactly: same coverage, same length, same density, in every panel.
Same clothing as in the reference, identical in all 8 panels, with the collar sitting the same way.
Neutral expression, mouth closed, no smile, eyes open in every panel except where stated.

DO NOT IMPROVE THE PERSON — this is a documentation sheet, not a portrait session
Do not slim or narrow the face. Do not sharpen the jaw. Do not smooth the skin or remove pores. Do not remove or thin facial hair. Do not remove grey or white hair. Do not make the person look younger or thinner. Do not remove or change the glasses. Do not change the hairstyle. Do not brighten the eyes or whiten the teeth.
Keep every asymmetry, every line and every irregularity that is visible in the reference.

LIGHTING AND SET
Seamless medium grey studio backdrop, uniform neutral grey, no gradient, only a very subtle vignette.
One large softbox key light from the front with symmetrical fill on both sides. Flat, even, low-contrast lighting, minimal shadows, no colour cast.
Exactly the same lighting in every panel.

CAMERA
85mm portrait lens, f/5.6, eye level, sharp focus edge to edge.
Photorealistic documentary portrait. Natural skin texture with visible pores. No beauty retouching, no skin smoothing, no plastic or waxy skin.

DO NOT INCLUDE
No text, no labels, no numbers, no arrows, no captions, no watermark and no logo anywhere in the image.
No hats, no earrings, no necklaces, no props and no background objects. Glasses are NOT an accessory here and must be kept if the reference has them.
No illustration, no 3D render, no anime, no stylisation, no painting.

B · 전신 시트 (4각도)

Create a full-body character reference sheet (model sheet) of the EXACT SAME PERSON as in the attached reference image. Read that person's face, hair, glasses, build and clothing from the reference and reproduce them; do not invent a different person.

LAYOUT
One single 16:9 image divided into 1 row x 4 equal panels, separated by thin white gutters.
FULL BODY in every panel — the whole figure from the top of the head to the shoes is inside the frame, standing on the ground, with a small even margin above the head and below the feet.
THE SCALE IS IDENTICAL IN ALL 4 PANELS: the figure is exactly the same height in every panel, the top of the head is at the same height in every panel, and all four figures stand on one single shared ground line.

ANGLES — the person rotates, the camera never moves. Camera at chest height, straight on, never looking down or up.
(1) front, 0 degrees.
(2) three-quarter left, 45 degrees.
(3) left profile, 90 degrees — exactly side on.
(4) rear, 180 degrees — seen from directly behind, the full back of the head and the full back of the clothing visible.

IDENTITY — READ ALL OF THIS FROM THE REFERENCE AND KEEP IT IDENTICAL IN ALL 4 PANELS
Same face, same bone structure, same skin tone and texture, same apparent age.
Same hair: same colour including every grey or white strand, same length, same parting, same hairline.
IF the person in the reference wears glasses, they wear exactly those glasses in every panel where they are visible, including panel (4) where the temple arm passes over the ear.
IF the person in the reference has facial hair or stubble, keep it exactly: same coverage, same length, same density.
SAME BUILD as the reference — same shoulder width, same waist, same posture and the same body proportions. Do not slim the body and do not broaden the shoulders.
SAME CLOTHING as the reference, identical in all 4 panels: the same garments, the same colours, the same fit, the same way the collar and cuffs sit, the same shoes. No logo, no print, no pattern and no brand mark anywhere.
POSE: standing straight and relaxed, arms hanging naturally at the sides, hands open and relaxed with all five fingers visible and correctly formed, feet shoulder-width apart. The same pose in all 4 panels. Neutral expression, mouth closed, no smile.

DO NOT IMPROVE THE PERSON — this is a documentation sheet, not a fashion shoot
Do not slim the body or the face. Do not lengthen the legs. Do not straighten the posture beyond the reference. Do not smooth the skin. Do not remove or thin facial hair. Do not remove grey hair. Do not make the person look younger. Do not remove or change the glasses. Do not change or upgrade the clothing.

LIGHTING AND SET
Seamless medium grey studio backdrop, uniform neutral grey, no gradient, only a very subtle vignette. One soft even shadow under the feet in every panel.

CAMERA
50mm lens, f/8, chest height, sharp focus edge to edge.
Photorealistic documentary portrait. Natural fabric texture and natural skin texture. No beauty retouching, no plastic or waxy skin.

DO NOT INCLUDE
No text, no labels, no numbers, no arrows, no captions, no watermark and no logo anywhere in the image.
No hats, no bags, no props, no furniture and no background objects. Glasses are NOT an accessory here and must be kept if the reference has them.

도구 둘

프롬프트로 못 고치는 것은 코드가 처리합니다.

• 전처리 스크립트 — EXIF 회전을 픽셀에 굽고, 여러 장을 참조 1장으로 묶습니다.
• 합본 스크립트 — 얼굴 시트 + 원본 전신 사진을 한 장으로 합쳐, 실패 ①의 처방을 실행합니다.

오래된 원칙이 또 확인됐습니다 — 규칙만으로는 또 샌다, 도구가 스스로 막게 해야 한다는 것입니다.

비용

항목	비용
4K 한 장	119원
실사 채택본	238원
실사 폐기본	357원
한 장 시험	238원
일러스트	238원
계	1,071원

폐기한 357원이 함정 둘(135도 문제·참조에 없는 옷 문제)을 사 온 셈입니다. 그 둘이 규칙이 됐으니 다음에는 같은 비용을 내지 않아도 됩니다.

참고 — 이 글에는 실제 인물 사진을 싣지 않았습니다

원본 사진은 실제 인물의 얼굴이라 초상권 문제가 있어 신지 않았습니다. 위 프롬프트는 특정 인물이 아니라 여러분이 가진 참조 사진에 그대로 적용할 수 있는 템플릿입니다. 대괄호 없이 "IF the person in the reference wears glasses…" 식의 조건문으로 쓴 것도 그래서입니다 — 누구의 사진을 넣어도 같은 문장이 작동합니다.
