Ultrasharp Experiment [Flux]

이것은 더 사실적인 Flux 이미지를 위한 디테일 강화 모델입니다. 이 모델들은 다양한 설정과 최적화 알고리즘을 사용하여 Flux에 더 많은 사진적 디테일을 추가하기 위해 제가 수행한 실험의 일련입니다.

프롬프트 형식은 ultrasharp photograph, [colors], [focus]입니다. 색상으로는 red 또는 blue and red처럼 하나 또는 두 개를 지정할 수 있습니다. 초점은 central focus 또는 spread focus로 지정할 수 있습니다. 프롬프트는 상대적으로 길고 상세해야 하며, 설명에는 Llama/Joy 스타일을 사용하세요.

기능

• 개별 잎이 더 많이 표현됨
• 빛나는 햇빛
• 더 정교한 나무 무늬
• 더 나은 보케 정의
• 더 균일한 반복 패턴
• 더 상세한 구성

버전

v3

초고선명 Flux 실험은 새로운 버전으로 계속됩니다. 이번에는 Ranger21 최적화 알고리즘을 사용하여 이미지를 지나치게 변경하지 않고도 선명하고 사실적인 스타일을 전이합니다.

참고: 매우 어두운 영역과 균일한 색상 영역에서 일부 색상 밴딩이 발생하며, 마치 압축 아티팩트처럼 보입니다. 이는 고해상도(hires) 작업 중 더 자주 발생합니다. hires 단계에서 LoRA를 비활성화하면 이러한 버그의 영향을 줄일 수 있습니다.

이러한 아티팩트는 학습 데이터에 존재하지 않았으므로 정확한 원인은 확실하지 않지만, 보케 및 배경 초점 효과와 관련이 있을 가능성이 있습니다.

v2

이것은 고해상도 사진 시리즈를 기반으로 훈련한 실험용 LoRA입니다. 극도로 선명한 디테일과 무채색의 색조에 초점을 맞췄습니다. 결과에 완전히 만족하지는 못했지만, 충분히 흥미로워 공유할 가치가 있다고 생각합니다.

예시 프롬프트

• ultrasharp photograph, brown and green, central focus. this is a highly detailed, macro photograph of a beetle, specifically a species of the family staphylinidae, resting on a green leaf. the beetle's body is a rich, burnished orange-brown color, with a glossy, almost metallic sheen that catches the light, creating subtle highlights and shadows. its exoskeleton is smooth and slightly textured, with visible segments and a defined, rounded shape. the beetle's head is prominent, featuring large, round, black eyes that are slightly reflective, giving it a somewhat alert expression. the antennae are long, slender, and segmented, extending outward from the head. the leaf it is resting on is a vibrant, fresh green with a fine, fuzzy texture, visible under magnification. the background is a soft, out of focus green, which helps to isolate the beetle and leaf, drawing attention to their intricate details. the photograph's sharp focus on the beetle and leaf contrasts with the out of focus background, enhancing the macro detail. the overall composition and lighting emphasize the beetle's striking appearance and the delicate textures of the leaf. the photograph captures a moment of stillness in nature, highlighting the intricate details of the beetle and the leaf it rests on.

• ultrasharp photograph, gray, spread focus. this is a high-resolution photograph capturing the grand, gothic revival-style corridor of a historic building, likely a university or government building. the corridor features an impressive series of pointed arches, supported by robust, intricately carved stone columns, each adorned with classical motifs. the arches are constructed from polished, light gray stone with subtle variations in texture, suggesting a blend of marble and granite. the ceiling is vaulted, with a series of ribbed, semi-circular arches that converge at the apex, creating a sense of depth and perspective. the floor is made of large, polished stone tiles that run parallel to the corridor, contributing to the sense of grandeur and timelessness. on the right side of the image, there is a large, ornate wooden door with intricate carvings and a metal handle, suggesting it might be an entrance to a chamber or office. the door has a rich, dark brown color with a slightly glossy finish, contrasting beautifully with the stone architecture. on the left side, the corridor widens, revealing a series of tall, narrow windows with stone frames, allowing natural light to filter in, casting soft shadows and enhancing the architectural details. the overall atmosphere is one of historical significance, academic prestige, and timeless elegance.

• ultrasharp photograph, red, central focus. this photograph captures a mesmerizing, high-resolution image of a single water droplet suspended in mid-air above a circular pool of water, creating a perfect, smooth, concentric ripple effect. the droplet is a perfect sphere, reflecting light and showing a slight curvature, with a glossy, almost metallic texture, indicating the water's surface tension. the pool of water beneath it is a deep, rich red, with subtle variations in hue and saturation, giving it a velvety, almost liquid texture. the background is a gradient of deep reds, transitioning from a darker, almost black shade at the top to a lighter, more vibrant red at the bottom, creating a sense of depth and dimension. the overall composition is simple yet striking, with the droplet being the focal point and the red hues providing a cohesive, dramatic color scheme. the lighting is soft yet directional, casting subtle shadows and highlights that enhance the droplet's three-dimensional appearance. the photograph exudes a sense of fluidity and elegance, with a strong emphasis on the droplet's delicate, suspended form.

• ultrasharp photograph, white and green, central focus. this photograph captures a serene, rural landscape dominated by a quaint, white, single-story cottage nestled in a vast, open field. the cottage, centrally positioned, features a steep, dark grey slate roof with several small, square windows and a black door. the structure appears rustic and charming, with a chimney extending from the roof's right side. the field surrounding the cottage is a lush, golden-brown grassland, slightly overgrown and wild, with tall, swaying grasses that seem to gently sway, hinting at a light breeze. the background is dominated by a majestic, rugged mountain range with steep, rocky slopes that transition into a verdant, green plateau at the top. the mountain's texture is rough, with exposed rock and patches of green vegetation, indicating a high altitude and possibly a remote, isolated location. the sky above is a dramatic, moody backdrop, filled with a mix of dark, stormy clouds and lighter, wispy cirrus clouds, suggesting an impending change in weather. the trees, sparse but dense, are a dark, rich green, adding depth to the scene and framing the cottage. the overall mood is tranquil yet slightly foreboding, evoking a sense of isolation and natural beauty. the photograph captures the essence of rural, highland scenery in a raw, untouched state.
