Ultrasharp Experiment [Flux]

这是一个用于生成更逼真Flux图像的细节增强器。这些模型是我使用不同设置和优化器进行的一系列实验，旨在为Flux添加更多摄影级细节。

提示格式为：ultrasharp photograph, [colors], [focus]。您可以指定一个或两个颜色，例如 red 或 blue and red。焦点可设为 central focus 或 spread focus。提示应相对冗长且详细，采用 Llama/Joy 风格的描述方式。

特性

• 更多独立的叶片
• 发光的阳光
• 更精细的木纹
• 更好的背景虚化效果
• 更均匀的重复图案
• 更细致的构图

版本

v3

Ultrasharp Flux 实验推出新版本，此次使用 Ranger21 优化器，在不大幅改变原图的前提下，传递出锐利、逼真的风格。

注意：在极暗区域或均匀色块中可能出现色带现象，类似于压缩伪影。这种现象在高分辨率处理时更为明显。您可以通过在高分辨率阶段禁用 LoRA 来减轻此问题。

这些伪影在训练数据中并不存在，因此我不确定其来源，但似乎可能与背景虚化和焦点效果有关。

v2

这是一个我基于一系列高分辨率照片训练的实验性LoRA，重点在于极致锐利的细节与柔和的色彩。我对结果并不完全满意，但认为它们足够有趣，值得分享。

示例提示

• 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.
