Paintstorm Studio — Intermediate: Blending & Smudge

Blend to serve form

Edges tell the viewer where to look. Use soft edges inside forms and hard edges at silhouettes or cast shadows. Smudge should pull light into shadow or shadow into light along the surface direction — like stroking fur.

Decision flow: soften inside forms, keep structure at silhouettes and cast shadows.

Edge type	Where	How
Soft	Interior transitions	Low flow brush, light smudge
Firm	Terminator (light→shadow)	Medium flow, minimal smudge
Hard	Silhouette & cast shadow	Crisp brush, no smudge

Hands-on practice

Soft sphere drill

Paint a sphere with five value steps. Smudge only the middle two transitions — leave the core shadow edge firmer.

<!-- Settings (escaped) -->
Brush: Soft round
Flow: 15–25%
Smudge: 5–12% strength
Direction: along curvature

Ribbon fold drill

Paint a folded ribbon; keep the fold’s peak sharp, blend the planes on either side. Like ironing fabric: edges crisp, surfaces smooth.

<!-- Tips -->
Smudge small, directional strokes
Avoid circular scrubbing (mud risk)
Re-introduce texture after blending

Blend without mud

Alternate: lay fresh paint, smudge lightly, then repaint accents. Think “push-pull” — not “smear.”

<!-- Mud-proof routine -->
1) Lay a deliberate stroke
2) Smudge in its direction 1–3 passes
3) Repaint accents with harder edge
4) Repeat as needed

Demos & visual aids

Soft edges blend, hard edges separate. Use both with intent.

Interactive — paint & smudge canvas

Toggle between Paint and Smudge. Paint lays color; Smudge drags color along your stroke for a soft transition.
