Tips

  • One clear subject or scene per prompt for best coherence.
  • Specify lighting and style to steer the output (e.g. "soft light", "cinematic").
  • Use aspect ratio that matches your deliverable.
  • Upgrade to SD 3.5 when you need the latest Stability quality tier.

1

Tell the model what should dominate the frame first.

2

Use lighting language early; it changes everything downstream.

3

When editing, describe what stays, not just what changes.

4

References help when continuity matters more than novelty.

Use precise visual language to control subject, composition, lighting, and style from the start.

Change only what matters
Edit

Preserve the useful parts of the image while steering the rest with masks, references, or prompt edits.

Hold the identity together
Reference

Bring in reference images or LoRAs when consistency is more important than exploration.

Best use cases
1

SD 3 Medium is strongest when the visual brief is specific about framing, style, and what should read first.

2

Use it for campaign images, product shots, subject consistency, or polished concept work.

3

When editing, say exactly what changes and what must remain untouched.

Pixio workflow
Step 01
Define the frame

Lock the subject, composition, and lighting direction before you chase style nuance.

Step 02
Protect consistency

Use references or edits when the same subject, style, or layout has to survive across versions.

Step 03
Polish to finals

Once the frame works, refine only the weak areas instead of rewriting the whole composition.

Best paired with
Upscale

Finish strong compositions by scaling them without rebuilding the frame from scratch.

Pixio Image Edit

Use editing tools after the initial generation when the composition is right but the details still need polish.
