Photo Relighting

Hand it a photograph of one thing and it relights the frame — another hour, another direction, another hardness — leaving the object, the surface and the background exactly where they were. Two fields.

Leather boot

We made two examples, from two different photographs: late sun on a cut-glass perfume bottle and cloudy light on a leather boot. One goes harder and warmer, the other softer and cooler, so the pair shows the two directions the light can go rather than one filter applied twice.

The framing, the object and the background stay where they were. What changes is the light and, above all, the shadow. Warm light also warms the background, so check the shadow first to be sure it is not just a colour change. You need a photo with a clear shadow: an evenly lit object comes back almost identical to the original.

Photo Relighting

What this makes

Hand it a photograph of one thing and it relights the frame — another hour, another direction, another hardness — leaving the object, the surface and the background exactly where they were. Two fields.

The whole template, in one piece. The steps below are the entire workflow.

How to use it

  1. Copy the whole template with the button above.
  2. Attach your photograph and paste the template in the same message.
  3. Replace the two FIELDS lines. In the second, give a direction and a height — without them nothing in the frame can move.
  4. Check the shadow first. If it is the same length and pointing the same way, the run graded the picture instead of relighting it, and that is the failure this template exists to catch.
  5. For a morning and an evening version, run the original twice rather than relighting the relit one.

What you swap

Before it runs

  • An actual photograph of the thing, attached to the message. There is nothing here for a description to work on.
  • A shadow already in the picture. Relighting is moving the one that is there; a flat, shadowless shot gives the run nothing to move.
  • One source. Two lights at two hours is not an hour, and the shadows stop agreeing.
  • A direction you can name. 'Nicer light' is a mood; 'low and from the left' is a position, and only a position moves a shadow.

When to reach for it

When the set is right and the light is wrong, or when one product needs a morning version and an evening one. Templates in this genre relight by tinting the whole picture, which moves nothing and convinces nobody, because a real change of hour moves the shadow.

What changes

  • One photograph in, one out — everything in the same position, lit at a different hour.
  • The shadow moves, changes length and changes edge, because the source moved rather than the colour grade.
  • The object keeps its own colour: warm light lands on it, it is not repainted warm.
  • The camera holds, so the two frames stack as a before and after of one thing.
  • Every highlight and shadow in the frame agrees with one named source, including the background's.
