이렇게 쓰면 돼요
제미나이(Gemini)는 구글이 만든 AI예요. 이미지 생성 기능이 있는데, 제대로 된 프롬프트를 쓰면 증명사진 수준의 결과물이 나와요. 나노바나나 프롬프트는 그 중에서도 실제로 써보고 검증된 조합이에요.
STEP 01
gemini.google.com 접속
구글 계정으로 로그인. 무료 플랜으로도 이미지 생성 가능해요.
STEP 02
내 사진 1장 첨부
가능하면 밝은 조명, 정면, 단정한 머리일 때 가장 이미지가 잘 나와요.
STEP 03
아래 프롬프트 복사해서 붙여넣기
남자/여자 버전 따로 있어요. 배경색은 옵션으로 추가 가능해요.
STEP 04
생성 후 마음에 드는 컷 저장
1장만 생성돼요. 사진이 계속 이상하게 나온다면 새로운 채팅창을 열어서 새로 시도해보세요.
쓰기 전에 꼭 확인하세요
⚠️ 주의사항
AI 생성 이미지라 실제 서류 제출용으로는 사용 불가해요. 취업 원서, 비자, 여권 등 공식 용도는 스튜디오 이용 필수.
SNS 프로필, 포트폴리오, 개인 용도로만 사용하는 걸 추천해요.
얼굴이 너무 측면이거나 어두운 사진은 결과물 품질이 떨어져요.
생성마다 결과물이 달라요. 완벽한 컷이 한 번에 안 나올 수 있어요.
무료 플랜은 하루 생성 횟수 제한이 있어요.
사진이 이상하게 나온다면 새로운 채팅창을 열어서 새로 시도해보세요.
