Stop Fluorescent Light Flicker with Your Camera's E-Shutter

The Problem: Color Bands in Office Light

You’re in a conference room, your client looks great, and you fire off a dozen shots. On the back of your camera, you see it: weird green or magenta stripes cutting across their face and suit. It looks like a bad filter. That’s fluorescent or LED flicker. These lights don’t shine steadily; they pulse 120 times per second in the US, 100 times in Europe. Your mechanical shutter’s moving slit captures those pulses at different stages, creating colored bands. It ruins shots. I once lost ten minutes of a 15-minute session fixing this, watching the client’s confidence fade with each messed-up preview.

Find Your Camera's Electronic Shutter Setting

Your fix is probably buried in your menu. Don’t panic. Grab your camera right now. Look for a menu tab called “Shutter Type” or “Drive Mode.” Inside, you’ll see options. “Mechanical” is your standard shutter. “Electronic” or “Silent” is what you want. On a Sony, it’s often under “Shutter/Silent.” On a Canon, check the “AF” tab for “Silent Shooting.” On a Nikon, look in the Photo Shooting Menu. If you’re using a Fujifilm, it might be a physical switch on the body labeled “MS/ES.” Write this down: your mission is to switch from Mechanical to Electronic. It takes ten seconds once you know where it is.

Set It, Shoot, and Check for Clean Results

Switch to the electronic shutter. Now, take a test shot under those awful office lights. Zoom in on the LCD screen—really zoom, to 100%—on a neutral area like a gray wall or your subject’s cheek. Before, you saw bands. Now, you should see clean, consistent color. The electronic shutter reads the entire sensor all at once, instead of a scanning slit, so it captures the light in a single instant of its cycle. No bands. Do a quick three-shot test: one at 1/125th, one at 1/60th, one at 1/200th. All three should be clean. If they are, you’ve solved it.

The Common Mistake: Using a High Shutter Speed

Here’s where people trip up. The electronic shutter fixes the color banding, but it introduces a new rule: watch your shutter speed. If you shoot faster than 1/125th of a second under artificial light, you might get a different, subtler banding or weird artifacts. Why? You’re capturing such a thin slice of time that you can catch the light in its “off” phase between pulses. Stick to 1/100th or 1/125th for safety. This is non-negotiable. I learned this shooting a CEO in a bright lab; at 1/500th, his striped tie developed strange moiré patterns that weren’t there in real life. Slowing down fixed it completely.

Your Payoff: Reliable Headshots Anywhere

The payoff is freedom. You can walk into a client’s headquarters, a hospital corridor, or a dimly-lit startup and know you’ll get a clean file. No more frantic searches for a window. No more explaining strange artifacts. Your lighting kit becomes a tool for shaping light, not your only source of it. One photographer I coach now books “office round” sessions, shooting five executives in their actual environments in an hour—impossible with flicker. Her clients love the authentic backdrop. Your technical consistency builds trust before you’ve even delivered a single edited photo.

So, find that menu setting today, shoot a test under your kitchen’s LEDs, and lock in that 1/125th shutter speed. Tuck this fix into your muscle memory. Your next client, waiting under the fluorescent glow of their boardroom, will never know there was ever a problem.
