Quick answer

## The short version

Use edge light to separate the subject from the background while controlling bright outlines. Separation should help the portrait rather than create a distracting glowing border.

## A capture or editing plan

Take a frame with the main light and background first. Add the edge source and inspect where it reaches hair, ears and shoulders. Change its angle or strength if highlights lose texture or spill into the lens. Compare the edge at the final crop, not just on a large monitor. Keep a version without the rim light when the background already provides adequate separation.

## When to change the approach

An overbright edge cannot be fixed reliably by darkening the whole image. Adjust the source or placement during capture when practical.

## Worked planning example

Planning example: Dark hair separates well with a subtle edge, but the same light produces an almost white ear. Repositioning the source improves separation without requiring a later reconstruction of the ear's texture.

## If the first attempt fails

When the bright edge becomes a white strip, reduce the rim contribution or adjust its angle before increasing overall exposure. Inspect loose hair and the shoulder closest to the source. Check whether light entering the lens creates haze that reduces facial contrast. A visible outline is useful only if the resulting edge and the central face remain readable in the exported portrait.

## Before you finish

1. Inspect hair, ears and shoulders separately.
2. Check for flare and clipped outlines.
3. Compare with a no-rim-light baseline.
