# Split Lighting: Decide How Much of the Face to Leave in Shadow

Use side lighting deliberately when a strong division between light and shadow supports the portrait. Check whether the darker side still contains the information the picture needs.

Quick answer

## The short version

Use side lighting deliberately when a strong division between light and shadow supports the portrait. Check whether the darker side still contains the information the picture needs.

## A capture or editing plan

Take a baseline with the light beside the subject and inspect the division across the face. Adjust the person's direction slightly to understand how the boundary moves. Decide whether a reflector or a small amount of ambient fill improves readability without losing the intended contrast. Review the eyes, glasses and jawline in the darker region before making the overall image brighter.

## When to change the approach

Do not brighten the whole frame solely to reveal one shadow area if that destroys highlights. Change the capture relationship or the intended contrast instead.

## Worked planning example

Planning example: A dramatic artist portrait works with a deep shadow, while the same file is too hard to recognize in a small directory. Keep the expressive version and capture a separate, more readable headshot.

## If the first attempt fails

When the shadow side becomes a featureless block, inspect the source file rather than brightening a compressed preview aggressively. Decide whether some darker-eye or cheek detail is needed for the intended portrait. Try restrained fill or a different head turn and compare with the original arrangement. A deliberately dramatic image can still require enough facial information for the subject to recognize and approve it.

## Before you finish

1. Check the darker side for needed detail.
2. Choose contrast for the actual use.
3. Keep highlight protection separate from shadow fill.
