# 📷 Analog Style — SDXL LoRA | Zavychroma XL

A style LoRA trained on 465 real analog film photographs scraped from

the film photography community, covering a wide range of cameras, film stocks,

subjects, and lighting conditions. It pushes Zavychroma XL toward authentic

analog aesthetics: organic grain, warm or faded tones, soft contrast, scanner

artifacts, and the beautiful imperfections of real film.

## ✅ Recommended Settings

- Sampler: DPM++ 2M Karras or Euler a

- Steps: 25–35

## 💡 Prompting Tips

- The trigger analogstyle alone already shifts the aesthetic — dial the LoRA

weight up/down to control intensity

- Name a film stock to push toward that specific look:

Kodak Portra 400, CineStill 800T, Fuji Velvia 100, Ilford HP5

- Describe light explicitly: golden hour, window light,

overcast soft light, neon street light

- For portraits add: `shallow depth of field, slight lens aberration,

film grain, scanned negative`

- For black and white: black and white, Ilford HP5, high grain, deep blacks

## 📌 Technical Notes

- UNet-only — text encoder untouched, so prompts fully control

subject and composition

- Attention-only (Q/K/V/Out) — clean style transfer without distorting

spatial layout

- Full depth coverage of down_blocks_2, mid_block, and up_blocks_0

= strong style influence even at moderate weights
