Direct Flash Night Photo

Hand it an ordinary photograph and it takes the picture again at night on a direct flash — where light falls off with the square of distance, so the near thing is blown out, the far thing is black, and only the background keeps the street's colour. Two fields.

Bowl of noodles

We made two examples, from two different photographs: a woman in a padded coat on a pavement, and a bowl of noodles on a restaurant table. In one the light falls off over a few paces, in the other across a room, and both split into a neutral foreground and a coloured background.

You get the photo as if shot at night on direct flash: the nearest thing close to blown out, a steep falloff and the far things black, with the street's colour only in the distance and a hard shadow just outside the subject. The face stays the same face. Check two things: whatever goes dark can vanish altogether, like the people further down the street, and loose contents such as noodles shift more than solid objects. Compare it with your photo before you use it.

Direct Flash Night Photo

What this makes

Hand it an ordinary photograph and it takes the picture again at night on a direct flash — where light falls off with the square of distance, so the near thing is blown out, the far thing is black, and only the background keeps the street's colour. 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 the photograph and paste the template in the same message.
  3. Replace the two FIELDS lines. Name the nearest and furthest things from the picture itself, so the falloff has two anchors.
  4. Check the near thing first: if it is not close to blown out, the flash was treated as a mood rather than a light source.
  5. Then check the background. If the whole frame is evenly lit, the falloff did not happen and it is worth another run.

Before it runs

  • A photograph, attached to the message. This takes a particular picture again; there is nothing to re-shoot without it.
  • Depth in the picture. A flat wall photographed head-on has no distances for the falloff to act on, and the result will just look bright.
  • A near thing and a far thing you can name. The whole effect is a ratio between two distances, and naming them is what makes it a measurement instead of a mood.
  • Acceptance that things will disappear. Anything far enough back goes to black, and that is the physics rather than a mistake.

When to reach for it

When something needs the look of a picture taken at night on a small camera: a gig, a menu, a zine, a late shot for a feed. Templates in this genre ask for a nostalgic flash photo look and hand back an evenly lit picture with a bright spot in it, because the falloff — the thing that actually makes a flash photograph — is never stated.

What changes

  • One photograph in, one flash photograph out — same subject, taken again in the dark.
  • Brightness falls off with the square of the distance, so what is nearest is nearly white and what is a few paces back is nearly black.
  • The ambient colour of the street survives only where the flash cannot reach, which splits the picture in two.
  • Shadows land hard and close, thrown away from the camera, because the light is at the lens.
  • One image, no grain overlay, no date stamp, no border.
