Step 4/5Strobist Lighting 101
A grid changes where the light goes, not what it feels like — the face keeps the same soft quality while the background stops being lit at all.

Final look

Base setup

Softboxes without grids spray light everywhere, which lifts grey backgrounds and kills mood. A grid narrows the beam while the diffusion still softens skin — learners see spill control as a separate skill from hardness.

Key notes

1Compare one frame without the grid at the same power — the background brightness change is the lesson.
2Feather the gridded box so the near cheek is bright and the far cheek falls off naturally.
3Flag the floor if spill still crawls forward; grids do not replace floor control on white epoxy.
4Do not confuse grid with snoot — skin should stay soft, only spill should shrink.
