What Is a Rim Light?
Beginner Guide to Edge Highlights, Separation & Professional Depth
What Is a Rim Light?
A rim light is placed behind or slightly to the side of a subject to create a bright outline along the edges. This highlight separates the subject from the background and adds depth to the image.
Why Rim Light Matters
- Separation: Prevents the subject from blending into the background.
- Dimension: Adds depth and a 3D feel.
- Professional look: Common in portrait, product, and advertising photography.
Rim Light Placements

Side Rim Light

Dual Rim Lights
Two lights used to highlight both sides for symmetry.
Modifiers for Rim Lighting
- Grids for directional control
- Strip softboxes for narrow contour highlights
- Bare bulbs for strong, sharp edges
