What Lumen Tool is for

Updated May 22, 2026

What it is

Lumen Tool is a browser-based portrait lighting simulator for photographers and videographers. It helps you test light placement, contrast, color temperature, and portrait lighting structure before setting up real lights.

What it is for

  • Test portrait lighting ideas before a shoot
  • Preview common lighting patterns
  • Compare warm and cool light balance
  • See how skin tone and backdrop affect the result

What it is not

Lumen Tool is a visual planning tool. It helps you understand direction, contrast, and balance faster. It does not replace a real camera test, a real studio setup, or a light meter.
