여행 사진 날씨 살리는 AI 프롬프트 가이드

흐린 날 망친 여행 사진, AI로 자연스럽게 맑은 날로 바꾸는 법.
인스타 필터 떡칠 없이, 진짜 원래부터 맑았던 것처럼.

🎯 이 프롬프트가 하는 일

• 흐린 하늘 → 자연스러운 맑은 하늘

• 칙칙한 색감 → 햇빛 든 자연 색감

• 역광/그늘진 얼굴 → 자연스럽게 밝게

• 합성 티 0%, 원본 그대로의 느낌 유지

🛠 준비물

1. Nano Banana Pro (나노바나나 프로) 접속

   • Gemini 앱 또는 Google AI Studio에서 사용 가능

2. 보정하고 싶은 여행 사진 (jpg, png)

3. 아래 프롬프트 (복사해서 쓰면 됨)

📋 프롬프트 (복사해서 쓰기)

사진을 먼저 업로드한 뒤, 아래 프롬프트를 그대로 붙여넣기

Look at this photo carefully. Identify the location, the time of day, the
season, and the direction the camera is facing based on visible cues
(architecture, vegetation, light direction, shadows, sun position if visible).

Now imagine: what would this EXACT same photo look like if it had been taken
on a normal sunny day at the same time, same season, same location, same
camera angle? Not a special golden hour, not a dramatic sunset — just a
regular nice day with good weather.

Render that version.

WHAT MUST STAY IDENTICAL:
- The person: face, expression, pose, exact body position, skin, hair, clothing
- Camera angle, framing, perspective, lens character
- All architecture, terrain, vegetation, roads, fences, every object
- Image orientation (do not rotate)
- The general feeling of the original photo's time of day

WHAT CHANGES (subtly, like real weather changing):
- Overcast grey sky → soft blue sky with some natural white clouds
  (not empty blue, real sky has clouds)
- Flat diffused light → gentle directional sunlight matching plausible sun
  position for this location and likely time of day
- Slight lift in overall brightness, as if the sun came out from behind clouds
- Natural color return: greens look like real healthy greens, stones look
  like sun-warmed stone, skin looks naturally lit
- Soft realistic shadows appear where they would naturally fall

BACKLIGHT / SHADOW ON FACE HANDLING:
If the subject's face is in shadow due to backlight, side light, or harsh
overhead light in the original, render the face as it would appear with
gentle natural fill light — as if soft ambient light from the sky and
surrounding surfaces (ground, walls, water) bounced back onto the face.

- Lift face brightness so features are clearly visible and pleasantly lit
- Eyes should not be lost in shadow; recover natural eye area brightness
- Skin tone stays consistent with the overall scene's white balance —
  do NOT make the face warmer or cooler than the rest of the photo
- Preserve original skin texture, pores, and any natural shine
- Keep a subtle, believable shadow gradient (the face should still feel
  three-dimensional, not flat-lit)
- Hair rim light from behind can remain if it exists — just don't let it
  overwhelm the face
- Think: how a skilled photographer would expose for the face in this
  scene using natural reflectors, NOT how Photoshop "Shadows +80" looks

If the face is already well-lit in the original, leave it as is.

CRITICAL RESTRAINTS — DO NOT DO THESE:
- Do NOT make it golden hour, sunset, or sunrise
- Do NOT add lens flare, bloom, or any "cinematic" effect
- Do NOT oversaturate. Real sunny days are not Instagram filters
- Do NOT add warm orange tint to everything
- Do NOT change the sun direction dramatically — infer from existing shadows
- Do NOT rotate or reframe the image
- Do NOT over-light the subject. If they were in soft light, keep them in
  soft light, just slightly brighter

The result should look like a casual phone photo someone would take on a
nice clear day — boring weather, not magazine weather. Like checking the
weather app and seeing "Sunny, 22°C" and going outside.

🧭 사용 순서 (3단계)

STEP 1. 사진 업로드

• Nano Banana Pro 채팅창에 보정할 사진 끌어다 놓기

• 한 번에 한 장씩 작업 추천 (여러 장 하면 퀄리티 떨어짐)

STEP 2. 프롬프트 붙여넣기

• 위 프롬프트 그대로 복사 → 채팅창에 붙여넣기

• 수정 없이 그대로 사용

• 영어 그대로 사용 (번역하면 결과 안 좋아짐)

STEP 3. 결과 확인

• 보통 10-30초 안에 결과 나옴

• 마음에 안 들면 같은 프롬프트로 한 번 더 (결과 매번 살짝 다름)

💡 결과가 별로일 때 조정 팁

🔴 너무 약하게 보정됐을 때

프롬프트 끝에 추가:

Make the weather change slightly more visible — clearer blue patches
in the sky, slightly more sunlight on surfaces.

🟡 너무 과하게/가짜 같을 때

프롬프트 끝에 추가:

Tone down the effect by 30%. Keep it subtle and believable.

🟠 얼굴이 그늘져서 어두울 때

프롬프트 끝에 추가:

The subject's face is significantly in shadow. Lift it confidently
with natural fill light — the goal is "I can clearly see her face"
not "subtle improvement."

🔵 골든아워처럼 너무 주황빛이 강할 때

프롬프트 끝에 추가:

Remove all warm orange tint. Use neutral midday daylight white balance.

⚫ 사진이 회전됐을 때

프롬프트 끝에 추가:

PRESERVE original image orientation exactly. Do not rotate.

⚠️ 주의사항

• 한 번에 한 장씩: 여러 장 한꺼번에 올리면 결과 흔들림

• 세로/가로 비율 유지됨: 원본 비율 그대로 나옴

• 인물 사진 권장: 풍경만 있는 사진은 다른 프롬프트가 더 좋음

• 저작권: 본인이 찍은 사진으로만 사용
