Yes—there are a few simple, common presentation techniques that work well on dark backgrounds.

The cleanest option is usually a very thin light frame: add a 1–2 px white or light gray border around each image. This separates the photo from the background without drawing too much attention away from the image itself.

Another approach is to place the image inside a wider white or gray mat/passepartout, similar to a framed print on a wall. This can look more deliberate and elegant than a heavy border.

If you want a more stylized look, a subtle light glow can work better than a dark shadow on a black background. Reflections are another possible effect, but they’re more decorative and can distract if overused.

For a more consistent gallery look, keeping images the same size or aspect ratio can also help them feel more intentional on the page.
