AI lighting editor for relighting a photo in words

Light decides how a photograph feels more than almost anything else in it. The same kitchen looks clinical under flat overhead light, inviting under low warm lamps, and bright and fresh in a morning beam from the window. Traditional editing can brighten, darken and tint an image, but it cannot move the sun: shadows stay where they fell when the shutter clicked. Relighting means producing a version of the picture in which the light itself is different, so highlights, shadows and reflections all shift to agree with a new source. An AI lighting editor makes that possible from a description. You name the source, its direction, its quality and its color, and the image is remade as if it had been lit that way. In ImageQuarry this is one of the core kinds of change: select a version, describe the light, review the new version.

Use the four words photographers use. Every light has a source (sun, window, lamp, neon sign), a direction (from the left, from behind, from above), a quality (hard and crisp or soft and wrapping) and a color (warm, cool, a specific hue). A request that covers all four leaves little to chance: "soft, cool window light from the left."

Time of day is a shortcut. "Midday", "golden hour", "blue hour" and "overcast afternoon" each imply an angle, a color and a softness that most people recognize. They are often the fastest way to change a whole outdoor scene. For indoor shots, name the fixtures instead: candles, a desk lamp, a skylight.

Watch the shadows, not just the highlights. A believable relight moves shadows to the opposite side of the new source and changes their length and edge. If the light now comes from the right but the shadows still fall to the right, the image looks wrong even if nobody can say why. Ask for the shadows directly when they lag behind.

Protect colors that must stay true. Strong warm or colored light shifts everything it touches. If a product's color or a person's skin tone must stay recognizable, say so in the request and check it in the result. A small shift may be fine for mood; a wrong product color in a shop listing is not.

Change light in steps. Going from harsh noon to candlelit night in one request asks for a lot. Try one move at a time: first the direction, then the time of day, then the extra lamps. Stepping also makes it easy to stop at the version you like best.

Check skin, eyes and reflective surfaces. Faces show relighting problems first: unnatural hotspots, eyes without catchlights, mismatched shadows under the nose and chin. Glass, metal and water should reflect the new light. Look at these areas before you use the picture.
