<p>中文速览：极光旧梦是一个面向动漫画风的光影增强 + 画质提升 LoRA，底模 Krea 2。它给二次元/动漫画面加一层电影感光照——暖调定向光、金色轮廓光与边缘辉光、柔和泛光、更丰富的中间调过渡，并收尾以更干净的细节与细腻胶片颗粒。无需触发词，它不改变画面里的角色与构图，只改变光怎么打在画面上、以及成图有多完整。权重建议 1.0（设计强度）或 1.3~1.5（光效更浓，画廊样图即用 1.5）。提示词只写「主体 + 构图 + 场景」效果最好，堆叠风格词会稀释它。样图的生成参数全部公开，可直接点开查看。</p>
<hr />
<p>AURORAL Nostalgia is a lighting and quality-enhancement LoRA for anime-style illustrations on Krea 2. It lays a cinematic light pass over 2D / anime artwork — warm directional light, golden rim light and edge glow, soft bloom and halation, richer mid-tone gradients — and finishes the render with cleaner detail and a subtle analogue film grain, while leaving your characters and composition exactly where your prompt puts them.</p>
<p>It does not change who or what is in the frame. It changes how the light falls on it, and how finished the result looks.</p>
<h3>Trigger word</h3>
<p>None. The effect applies automatically — just describe your subject and scene.</p>
<h3>What it does</h3>
<ul>
<li>Lighting: warm directional light, golden rim light and edge glow, soft bloom / halation, stronger separation between lit areas and shadows.</li>
<li>Quality: cleaner rendering with finer line and detail retention, smoother tonal gradients, gentle depth of field and a fine film-grain finish — the "finished illustration" look rather than flat output.</li>
<li>Colour: warm–cool separation and a nostalgic film grade, richer without going oversaturated.</li>
</ul>
<h3>Recommended strength</h3>
<ul>
<li>1.0 — designed strength: a clear lighting and quality upgrade, content intact.</li>
<li>1.3 – 1.5 — noticeably stronger glow, bloom and film character. Our own gallery samples were made at 1.5.</li>
<li>0.8 and below — the effect fades quickly.</li>
<li>On Turbo / quantized Krea 2 checkpoints the effect is a little weaker than on the full-precision base.</li>
</ul>
<h3>Works best with</h3>
<ul>
<li>Anime and semi-realistic anime illustrations — single character, half-body or full-body.</li>
<li>Scenes that profit from atmosphere: dusk, night streets, lantern light, interiors, gardens, window light.</li>
<li>Prompts that already describe the subject well — let this LoRA supply the light and the finish. Your own style words dilute it.</li>
</ul>
<h3>Honest limitations</h3>
<ul>
<li>A declared style in your prompt wins. If you ask for completely flat, unlit cel shading, the LoRA will mostly add colour and grain instead of repainting the light.</li>
<li>Best with content-only prompts (subject / framing / scene) rather than stacked style keywords.</li>
<li>At 1.5+ on very soft or low-detail scenes some micro-detail is traded for mood; drop to 1.0–1.2 when you want the texture back.</li>
</ul>
<h3>Notes</h3>
<p>All gallery samples were generated with this LoRA on Krea 2, 10 steps, CFG 1.0, euler / simple, at 1024 px on the short side. The generation data is public — open any sample image to read its full prompt and settings.</p>

AURORAL Nostalgia · 极光旧梦

<p>v1.1 更新 · 2026-10-25</p>
<p>中文速览：v1.1 是对极光旧梦的一次定向优化：重新调校了复古色彩、光影层次与服装细节的表现，并修复了 v1.0 在特定服装提示词下容易出现的服饰偏移问题。整体风格气质与用法保持不变：无需触发词，推荐权重 1.0（设计强度）或 1.3–1.5（光效更浓，画廊样图用 1.5）。</p>

v1.1 的优化（相对 v1.0）
<ul>
<li>服饰偏移修复：v1.0 在「白衬衫 + 裙子」类提示词下，服装容易被画成日式校服元素（水手领 / 百褶裙 / 过膝袜）。同提示词、同种子三组对照：v1.0 三组全部出现该类元素；v1.1 三组均为普通衬衫领 + 自然垂坠长裙，零校服元素。</li>
<li>摄影光感更强：本次样图（8–10 步、CFG 1.0、短边 1024、权重 1.5）里，窗光、丁达尔光柱、台灯暖光、逆光轮廓的层次与胶片质感比 v1.0 更明确，画面完成度更高。</li>
<li>风格与用法不变：给动漫 / 半写实插画加一层电影感光照 + 复古胶片调，保留人物与构图；提示词只写「主体 + 构图 + 场景」效果最好，堆风格词会稀释它。</li>
</ul>

<p>English: v1.1 is a targeted optimisation of AURORAL Nostalgia — the vintage colour, lighting depth and outfit detail have been retuned, and the outfit drift that v1.0 sometimes showed on certain clothing prompts is fixed. The overall mood and usage are unchanged: no trigger word, recommended strength 1.0 (designed) or 1.3–1.5 (stronger; gallery at 1.5).</p>

What v1.1 improves (vs v1.0)
<ul>
<li>Outfit drift fixed. v1.0 could drift plain "white shirt + skirt" prompts into Japanese school-uniform elements (sailor collar, pleated skirt, thigh-high socks). In a same-seed paired test (3 prompts): v1.0 showed those elements in 3/3; v1.1 in 0/3.</li>
<li>Stronger photographic light. The new samples (8–10 steps, CFG 1.0, 1024 px short side, strength 1.5) show clearer window light, dust beams, practical lamps and rim light, with a more finished, film-like look than v1.0.</li>
<li>Same mood and usage. A cinematic light pass plus a vintage film grade, leaving subject and composition untouched. Content-only prompts work best.</li>
</ul>

Recommended settings
<ul>
<li>Strength: 1.0 — designed strength; 1.3–1.5 — clearly stronger glow and film character (the gallery was made at 1.5).</li>
<li>Sampling: 8–10 steps, CFG 1.0, euler / simple or dpmpp_2m / simple, 1024 px on the short side.</li>
<li>On Turbo / quantized Krea 2 checkpoints the effect is a little weaker than on the raw bf16 base.</li>
</ul>

Honest limitations
<ul>
<li>A declared style in your prompt wins over the LoRA — content-only prompts are the way.</li>
<li>At 1.5+ on very soft or low-detail scenes some micro-detail is traded for mood; drop to 1.0–1.2 when you want the texture back.</li>
<li>On short prompts the trigger words can occasionally appear as lettering — add <code>text, watermark, AURORAL, Retro</code> to the negative prompt.</li>
</ul>

Samples
<p>This version adds 18 new samples (cover first, then portrait 9:16, then landscape 16:9). The generation data is public — open any sample image to read its full prompt and settings.</p>
