Why does an LED video wall look worse in my dance photos than in my colleague’s?

I photographed a dance production with a large LED video wall as the backdrop. I used a Sony A7 III with a 70-200mm lens at 1/200s to keep the dancers sharp, while my colleague used a Canon 6D Mark II at 1/125s. My images have sharper dancers, but the LED background looks banded/uneven and generally worse. My colleague’s dancers are a bit blurrier, but the background looks better.

Is this mainly caused by shutter speed, electronic vs mechanical shutter, or mirrorless vs DSLR?

To me, the difference is that your colleague's picture is better - or at least differently - composed. You've shot from an angle where the dancers take up half to two thirds the height of the screen, while your colleague has shot from an angle where they're taking up about a third. This leaves a lot more of the screen visible.

There's also what's on the screen at the time - your colleague has a shot where there is interesting detail (the skyscrapers) in the upper half of the screen, while your shot essentially just has sky. That just naturally makes your shot look less interesting.

All this is far more important than camera or shutter speed.

This is mostly not about mirrorless vs DSLR. The main issue is the LED wall and how it refreshes/pulses, combined with your exposure timing.

A fast shutter speed can catch the screen mid-refresh, causing uneven brightness or horizontal banding. If electronic shutter was used, rolling-shutter effects can make this worse. That’s why your 1/200s shot can show a uglier background while your colleague’s 1/125s shot looks smoother.

What to try:

  • use the mechanical shutter instead of electronic/silent shutter
  • try slightly slower shutter speeds to better sync with the screen refresh
  • enable anti-flicker if your camera offers it

There’s also a composition difference: your colleague’s framing shows more of the screen and happens to capture more interesting content on it, which makes that image look better regardless of camera model.

So: sharper dancers came from your faster shutter, but the worse-looking LED wall is mainly a refresh/flicker/rolling-shutter timing issue, not a Sony-vs-Canon issue.
