우선, 기본적으로 포토샵 또는 이미지 편집 툴을 사용하실 줄 안다는 걸 깔고 작성하며, 제가 작업하는 방식이 정답이 아니기에 틀린 부분이 있을 수도 있어, 이 점 양해부탁드립니다.
사용 툴 : 오토매틱좌 webUI
사용 모델 :
abyssorangemix v2 hard + basilmix 0.8:0.2 믹스 모델

손 보정 네거티브로 유명한 bad_prompt와 유사하지만, 손을 포함한 전신의 망한 이미지를 훈련시켜 인체 삐꾸가 나는 것도 어느정도 방지해주는 임베딩입니다. 전 웨이트를 1.0으로 줘서 사용하지만, 애니체를 주로 사용하시는 경우 그림체가 달라질 수 있어 실험해보시면서 강조치를 조절하시는 것을 추천드립니다.

뒷 배경을 날려주는 익스텐션입니다. 웹UI의 익스텐션 탭에서 available -> load from 클릭 후 위 익스텐션 이름으로 검색하셔서 설치하시고, 가급적이면 웹UI를 재시작하시는 것을 권장드립니다.

샘플러 및 hires.fix 세팅
고해상도로 뽑을 시 작업시간이 너무 오래걸린다 싶으시면 일단 hires.fix는 체크해제하시고, 저해상도로 txt2txt를 뽑으신 이후 이후 마음에 드는 이미지를 image2image 과정에서 업스케일링하셔도 무방합니다.
위 세팅으로 이미지를 뽑았는데, 머리 위쪽이 잘렸습니다. 버리기 아까운 것 같아, 몇가지 작업을 해봅시다.
아웃페인팅을 이용한 확장
image2image탭에서 동일 프롬 적용 후 위에서 뽑은 이미지를 넣어주고, 사진과 같이 세팅해줍니다. 전 위쪽으로만 확장할거라 direction을 up에만 체크했지만, 원하시는 확장방향을 체크해주시면 됩니다.
Denoising strength의 경우는 정답이 없습니다. 제 경우엔 0.6~0.8사이에서 결과물을 봐가면서 조절하지만, 이번엔 귀찮아서 확장만 돌리고 포토샵으로 수정해버릴 겁니다.
음....삐꾸가 좀 많이 난 것 같지만...포토샵으로 어떻게든 수정해봐야겠네요.
확장된 부분을 잘라내기 해서 크기를 짜맞추고, 뒷 배경은 단색으로 밀어버렸습니다. 어차피 뒷 배경을 다시 날려버릴거라, 괜찮습니다.
하는 김에 다리쪽에 스타킹 색상을 대충 칠해서, image2image에서 스타킹을 신겨볼 수 있도록 하죠 :)
배경 날리기
사진과 같이 배경을 날릴 이미지를 image2image로 불러오시고, 스크립트에서 ABG remover를 선택해줍니다. 이 때, 이미지의 해상도는 원본 이미지와 동일한 해상도를 적용하시고, 전 이 과정에서 i2i를 한번 돌려볼 계획이므로 denoising strength를 0.5로 줘봤습니다. i2i를 돌릴 생각이 없으시다면 0으로 두고 돌리면 됩니다. 샘플링 스텝은 24로 적혀있는데, 실제론 32정도로 적용했습니다.
위 이미지와 같이 3개의 이미지가 만들어졌을겁니다.
하나는 i2i의 결과, 다음은 배경을 날린 이미지, 마지막은 마스킹을 위한 알파채널 이미지입니다. 전 1번과 2번 이미지만 사용할 예정입니다.
배경 합성
사진과 같이 1번 이미지를 포토샵에 불러온 이후, 2번 이미지를 그 위에 올려줍니다.
오피스 레이디인데, 배경이 오피스가 아니라 뭔가 좀 아쉬우니, 오피스 데스크 이미지를 넣어주는게 좋을 것 같네요.
이 부분은 개인의 이미지 편집 역량에 달린 문제라 자세히 적긴 어려울 것 같네요. 제가 한 작업은 아래와 같습니다.
오피스 데스크 관련 이미지를 찾아서 배경에 합성,
캐릭터의 그림자 추가,
의자의 대략적인 형상 대충 마우스로 그리기
이제 다음단계인 i2i로 넘어가봅시다.
2. i2i를 통해 디테일업
image2image
배경에 데스크가 추가되었고, 스타킹도 신었으니 아래와 같이 프롬을 조금 변경해봅니다.
masterpiece, (best quality:1.1), (extremely fine and beautiful:1.1), (best illumination), (semi_realistic), (illustration:1.1), (office desk with monitor and keyboard background:1.5), (1 beautiful lady:1.2), (white see-through blouse ornated with lace embroidery tucked in tight black miniskirt:1.5), (black pentyhose:1.2), view from front, (full body), (sit on office chair:1.5), FEMININE, (beautiful face), adult, (pale white skin:1.2), (large breast:1.0), cleavage, (slender), wide hips, (arm + hand + 1thumb + 4finger), (detailed beautiful eyeliner eyeshadow mascara:0.8), (by Joao Ruas), by John William Waterhouse, [by Gil Elvgren], (long black hair:1.3), looking at viewer, smile, (cinematic lightings:1.5), (soft volumetric lighting:1.2), best ratio four finger and one thumb
i2i 세팅은 위와 같이 맞춰보겠습니다.
어차피 얼굴이나 디테일은 나중에 다시 잡을테니, 대충 합성한 배경이 원래 이미지와 잘 녹아들 수 있도록 가볍게 이미지 처리를 돌린다고 생각하시면 될 것 같습니다.
i2i를 약 스무장정도 돌려보고, 그 중 가장 마음에 드는 이미지를 선택했습니다.
업스케일링
extras 탭에서 이미지를 업스케일링해줍니다. 제 경우 반실사체는 SwinIR_4x 업스케일러가 가장 궁합이 잘 맞는 것 같아 해당 업스케일러를 사용하지만, 사용하시는 그림체에 따라서 결과물이 달라지니 성향에 맞는 업스케일러를 선택하셔도 무방합니다.
가로세로 두배로 업스케일링 한 이후, 이제 디테일업 작업에 들어가봅시다.
디테일업
우선 얼굴 부분을 포토샵에서 크롭해줍니다. 얼굴부분만 크롭했음해도 960*1024 해상도로 꽤 크기가 크네요.
이렇게 크롭해주는 이유는, 아무리 vram이 높은 그래픽카드일지라도 1920*3168정도의 고해상도 이미지작업을 하는데는 시간도 오래걸리고 작업자체가 불가능할 경우가 많기때문에, 부분별로 작업을 하기 위함입니다.
크롭한 이미지를 i2i의 inpaint 탭에 넣고, 위 사진과 같이 inpaint할 영역을 지정해줍니다.
여기서 제 경우엔 모델을 abyssorangemix v2 nsfw + basilmix 0.7:0.3 믹스 모델로 교체하고, LORA에서 눈 부분 표현을 개선해주는 LORA를 사용합니다.
https://civitai.com/models/5529/eye-lora
제 경우엔, , loraeyes 이렇게 프롬프트에 추가해줘서 사용하고있습니다만, 사용하지 않으셔도 무방합니다.
모델교체의 이유는 hard모델의 경우 실사체의 느낌이 과하게 강해지는 경향이 있어서입니다. hard->nsfw->sfw로 갈수록 그림체가 좀 더 일러스트에 가까워지므로, 이 부분 참고 부탁드립니다.
종종 nsfw모델조차 실사느낌이 너무 강하다 싶으면 sfw모델과 바질믹스를 병합한 모델로 넘어가곤 합니다.
인페인팅 결과는 위와 같습니다.
위와 같은 방법으로 옷 부분도 인페인팅을 진행하되, 상대적으로 심플한 하의는 그대로 두고 상의부분만 인페인팅을 진행하겠습니다.
인페인팅한 조각그림들을 업스케일링되었던 원본 이미지에 포토샵을 통해 합성해보았습니다.
서랍장의 손잡이가 사라진 것이 아쉬워, 다른 이미지에서 손잡이를 뜯어와서 합성하고, 포토샵의 픽셀유동화등의 기능을 통해 손이나 얼굴 등 어색한 부분을 조금씩 손봐주는 것도 좋습니다.
사실 저도 이정도까지 복잡하게 작업하는 경우는 정말 아쉬운 이미지가 있을 경우에만 그렇고, 보통은 text2text->img2img->디테일업 이렇게 포토샵을 통한 배경작업 없이 바로 웹UI를 통해서만 진행하고 포토샵은 크롭 및 합성에만 사용하는 경우가 대부분입니다.
긴 글 읽어주셔서 감사하며, 제 필력이 모자라 전달력이 떨어지는 점 양해 부탁드립니다 ㅠㅠ
AI관련해서 전혀 몰랐는데 이것도 그리 쉬운 작업이 아니군요.ㄷㄷㄷ
쉽게 가자면 그냥 txt2txt에서 hires.fix만 적용해도 그럴듯한 이미지들이 나옵니다. 거기서 한단계 퀄리티를 올리려면 들어가는 품이 좀 많은 편이죠 ㅠㅠ

비램이 부족해서 그런지 포토샵과 웹ui를 동시에 구동하면 포토샵이 뻗어버리더군요...ㅎㅎ... 부정프롬프트는 다른곳에서 퍼온 부정 프롬프트입니다. 원래는 저 프롬의 반의 반도 안하는 프롬을 썼는데 저 프롬이 제가 원하는 그림체에 딱 맞게 표현해주더군요
오~ 감사합니다. 강좌 더 부탁드립니다~!!
대단합니다!!
강좌 감사합니다. 항상 잘 보고 있습니다.
와...AI로 하는건 맞는데 손이 많이 가네여 ㄷㄷ
선생님 많이 배우게 되어서 쪽지인사 남겼습니다 ㅎㅎ 감사드립니다.
항상 감사합니다!
좋은 글 감 사 합니다
