📌 Caption + SDXL aDetailer + Upscale — Workflow Overview

This workflow is designed as an end-to-end enhancement pipeline for improving existing images using three major stages:

1. Automatic Captioning (JoyCaption)

2. Multi-stage SDXL aDetailer refinement

3. High-quality 2×/4× upscaling

It is especially useful for batch-processing portrait images, NSFW or SFW, while keeping full control over detail restoration (faces, hands, skin, body parts), composition integrity, and final resolution.

🔹 1. Automatic Captioning (JoyCaption)

The pipeline begins with JoyCaption:

• Loads images from a directory via ImageBatchPath

• Applies the user-defined Extra Options block (lighting, camera info, text removal, etc.)

• Produces a clean SDXL-style prompt

• The prompt is shown via ShowText and sent directly into the conditioning stack

This step is ideal for:

• Captioning large datasets

• Creating prompts from real photos

• Generating consistent SDXL prompts for further enhancement or LoRA training

🔹 2. Multi-Stage SDXL aDetailer Refinement

The core of the workflow is a chain of aDetailer passes, each dedicated to a specific target area:

• Face

• Hands

• Teeth

• Armpits

• Breasts

• Vagina

• General body segmentation

Each pass includes:

• YOLOv8 detectors from the Impact Pack

• SAM for accurate mask generation

• SDXL inpaint refinement with positive/negative conditioning

• Full previews for each refinement stage

This allows extremely fine-grained control and produces:

• Cleaner face geometry

• Corrected hands

• Better skin continuity

• Consistent anatomy in NSFW work

• Reduced artifacts from low-quality images

The workflow is modular: users can disable or remove specific detailers as needed.

🔹 3. High-Resolution Upscaling (2× or 4×)

Upscaling is handled through:

• UpscaleModelLoader (4x_NMKD-Siax_200k)

• ImageUpscaleWithModel for AI-based enhancement

• ImageScaleBy for additional clean integer scaling

• Two final outputs:

  • 2× upscaled

  • 4× upscaled

This results in:

• Clean, crisp edges

• Preservation of style

• Better texture definition

• High-resolution images suitable for posting or further processing

The Set/Get image node pair provides a lightweight way to reuse the intermediate image cleanly across the upscale branch.
