Color gel

What it does

Acetate or polycarbonate filters change flash/strobe spectrum. Stronger gels need less power for same saturation; weak gels need more power or stack.

When to use it

Fashion rims, athlete color splits, background washes, opposing teal/warm lessons.

Placement basics

Set neutral skin key first. Add gelled rims low power; flag gel spill toward face. Background gels separate from face lighting when possible.

Distance & power

Rims 1–2 stops under neutral key common. Saturated look ≠ high power — often opposite.

Practice on set

1. Neutral key hero frame.
2. Add one gelled rim; flag face.
3. Add opposing gel rim; balance powers.

Pairs well with

• 

  Stripbox

  Stripboxes are tall, narrow soft sources — perfect for edge lines on faces, bottles, and packaging.

• 

  Softbox

  A softbox is the default directional soft modifier — rectangular or square diffusion in front of flash with controlled spill compared to umbrellas.

• 

  Flag / cutter

  Flags (cutters, barn doors, black flats) block light — they subtract instead of add.
