When to use relight

  • Standardizing lighting across product photos shot in different conditions
  • Creating multiple mood variations from one image
  • Fixing flat or unflattering lighting on an existing photo

​
Tool chaining tip

Remove the background first, then relight. This gives the AI a cleaner subject to work with and produces sharper edge lighting.
