<p>AURORAL Retro is a soft, nostalgic vintage-aesthetic style LoRA for Krea 2. It washes a scene with warm faded colour, gentle contrast, fine film-like grain and a quiet, dreamy mood — while leaving the content of your prompt where you put it.</p>
<p>It is tuned for people and quiet everyday scenes: portraits, old rooms, rainy streets, courtyards, still life. It is a mood layer, not a subject changer.</p>

<h3>Trigger word</h3>
<p>Put <code>AURORAL Retro</code> at the end of the prompt (that is the form it was trained with).</p>

<h3>Recommended strength</h3>
<ul>
<li>1.0 — the designed strength. Balanced and clean.</li>
<li>1.3 – 1.5 — clearly stronger vintage / film feel. On our own test sets this scored best on average (1.5 was the top setting on 6 of 10 library prompts, and on all 3 anime test prompts).</li>
<li>0.8 and below — not recommended: the style fades and the base model's own texture comes through more.</li>
<li>On Turbo / quantized checkpoints (e.g. krea2 Turbo nvfp4) the effect is a little weaker than on the original raw bf16 base.</li>
<li>A ×2 pre-scaled file is included in this version: load it and set 1.0 to get the same result as 2.0 on the main file.</li>
</ul>

<h3>Example prompts</h3>
<pre>a photograph of a young woman sitting beside a large window in the morning, holding a ceramic cup, wearing a cream knit sweater, half body shot. AURORAL Retro</pre>
<pre>a photograph of a young woman turning her head over her shoulder on a wet street at night, wearing a dark coat, city lights behind her. AURORAL Retro</pre>
<pre>a quiet courtyard with a wooden bench and hanging paper lanterns at dusk. AURORAL Retro</pre>
<p>Suggested negative prompt (see the note below): <code>text, watermark, signature, letters, AURORAL, Retro</code></p>

<h3>What it does well</h3>
<ul>
<li>Portraits and half-body shots of a single person; skin, fabric and light get the vintage treatment.</li>
<li>Quiet interiors and street scenes — old cafes, bookshops, corridors, courtyards, wet asphalt.</li>
<li>Works on both photographic and 2D / anime prompts (see the anime samples in the gallery); on anime prompts it acts as a warm, faded colour grade rather than a redraw.</li>
</ul>

<h3>Honest limitations</h3>
<ul>
<li>Prompt style wins over the LoRA. If your prompt already declares a strong art style ("seinen manga illustration", "flat colour comic", "smartphone UI screenshot"), the LoRA only shifts texture and colour; it will not override that declared style.</li>
<li>Best with content-only prompts. Describe subject / scene / framing and let the LoRA supply the look. Writing your own style words dilutes it.</li>
<li>Occasional trigger text. With short prompts the model can sometimes render <code>AURORAL Retro</code> as lettering inside the image (about 20% of generations in our short-prompt tests; 0/30 on long third-party prompts). Adding <code>text, watermark, AURORAL, Retro</code> to the negative prompt removes it in our tests.</li>
<li>Weak on hard-styled or crowded scenes: decorative flat graphics, anime character sheets and busy multi-subject compositions keep their own look.</li>
<li>Extremes of the strength slider degrade: at 1.5+ a soft scene can lose micro-detail; if that happens, drop to 1.0 – 1.2.</li>
