Ultrasharp Experiment [Flux]

これは、より写実的なFlux画像のために設計されたディテール強化モデルです。これらのモデルは、Fluxにより写真的なディテールを追加するために、さまざまな設定とオプティマイザーを使用して私が実施した実験の系列です。

プロンプトの形式は ultrasharp photograph, [色], [焦点] です。red や blue and red のように、1つか2つの色を指定できます。焦点は central focus または spread focus です。プロンプトは比較的長く、詳細で、Llama/Joyスタイルの記述を使用してください。

特徴

• 個々の葉がより多く表現される
• 光る日差し
• 細かい木目
• ボケの定義が向上
• より均一な繰り返しパターン
• より詳細な構図

バージョン

v3

Ultrasharp Flux実験は、新しいバージョンで継続されます。今回はRanger21オプティマイザーを使用し、画像をあまり変更せず、シャープでリアルなスタイルを転送します。

注意：非常に暗い領域や均一な色の領域に、圧縮アーティファクトのように見える色のバンドリングが発生することがあります。これは高解像度処理時により顕著になります。これらのバグの影響を軽減するには、高解像度処理中にLoRAを無効にすることで対応できます。

これらのアーティファクトはトレーニングデータには存在しなかったため、発生の原因は不明ですが、ボケや背景フォーカス効果に関連している可能性があります。

v2

これは、極めてシャープなディテールと控えめな色調に焦点を当てた高解像度写真のシリーズを用いて訓練した実験用LoRAです。結果には完全には満足していませんが、共有するに値するほど興味深いものだと考えています。

例プロンプト

• 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.
