SDXL portrait baseline — change one variable at a time

An official, intentionally plain SDXL starting point for controlled tests. Keep the seed and settings fixed, generate the baseline, then change only subject, light, camera, or style. This is a template, not a claim that one setting wins on every checkpoint.

Workflow stages

  1. Baseline

    Choose a fixed seed and render this prompt without style additions.

    Record checkpoint, seed, sampler, steps, CFG, and size.

  2. Single-variable test

    Change one button group only. Keep every recorded setting fixed.

    Compare at the same output size.

  3. Save the winner

    Keep the version that improves your stated goal, then share the exact recipe.
