Question

What refresh rate stops banding on camera?

Ask for a high refresh rate rather than a high frame rate: banding on camera is a refresh problem, and it shows on broadcast long before the eye sees it.

Why banding appears

A camera shutter samples the wall at a different rhythm from the panel refresh. Where the two disagree, horizontal bands appear in the recording and in photographs.

What to specify

For broadcast, film and photo work the wall is specified with a high refresh rate and checked with a camera on site, not only on a data sheet.

Angle and shutter

Viewing angle and shutter speed affect the result too. A wall filmed at an angle needs the same check, and the test is repeated at the worst seat.
