Backlight
Category: Lighting, Photography Technique
Definition: A light source positioned behind the subject, pointing toward the camera, that creates edge highlights, separation from background, and adds depth. Creates a rim of light around the subject defining shape and adding dimension.
Why It Matters: Separates subject from background; adds professional quality and depth; creates visual interest; defines shape and form; particularly effective for hair, fabric edges, and creating premium feel.
Use Cases: Creating separation in on-model photography, highlighting hair and fabric edges, premium product photography, adding depth to flat images, creating dramatic lookbook lighting.
Example of Real Use Case: A high-end activewear brand adds backlighting to their lookbook photography, creating glowing edge highlights on models and fabric that emphasize movement and quality. The dramatic effect increases social media engagement by 58%.
Software/Service: Strobes with grids or snoots, LED strip lights, Profoto systems, barn doors for light control
Common Issues: Backlight too bright creating flare or washing out subject, lens flare from light hitting camera, overexposed edges, inconsistent backlight across series, difficulty balancing with key and fill.

✓ Do balance intensity with other lights
