A cyclorama (or “cyclo/cyc”) wall is a seamless studio background with a smooth curved transition between the wall and floor, so there’s no visible corner line. This creates the “infinity” look where the background seems to continue without an edge.

In practice, the term can overlap with “seamless background,” because both serve the same visual purpose. The main difference is usually scale and permanence:

• Seamless paper/background: temporary or portable setup.
• Cyclo wall: built-in studio installation, often larger and painted, commonly white.

Cyclo walls are common in professional studios, especially larger spaces, because they let subjects appear to float in space and make it easy to light the background evenly or create gradients. They’re also useful when a clean cutout/keyed look is needed.

So: a cyclo wall is essentially a permanent, architectural version of a seamless background.
