The Secret No One Tells You About Lighting Great Night Portraits

Want to photograph portraits that don't look like deer caught in headlights or someone telling campfire ghost stories? While we might obsess over the Milky Way, the stars, or even light painting, most photographers don't figure out how to take fantastic portraits of people in their night or astro-landscape photos—something that looks polished, dramatic, and intentional. Here's how.

A Discussion of Event Photography (Don't Worry, I'll Tie It In With Night Portraits!)

This was one of quite a few photos from a fundraiser at Skirball Cultural Center in Los Angeles for the Exceptional Children's Foundation. I like keeping myself on my toes by doing several genres of photography, so I decided to take the job as event photographer for this occasion. Here, as the sun is setting, I set the camera to expose for the ambient light outside, then adjusted the flash to 1/8 strength for fill light to illuminate the two subjects.

Why am I showing you a day photo using a flash? This is an article about night portraits, after all.

Because I want to emphasize that they use the same principle. In both instances, you do the following:

  • Expose for ambient light

  • Adjust the off-camera flash to fill in the subject

Conceptually, night photography is the same, only the exposure is much longer. There isn't really much difference.

First, you expose for ambient light, then you adjust your light or flash to fill in the subject to taste!

Now, there is more to it than that, of course. But the basics are the same. As the sun sets or you move indoors, keep adjusting the camera's settings to expose properly for the ambient light, then adjust the flash to fill in the subject to taste, usually a little brighter to lift them from the background a bit.

For a broader foundation in shaping and controlling light, see Fundamentals of Lighting.

And this is how it's done for night photography. It's really no different.

The Ability to Move Slowly

I ran quite a bit to light this photo. After popping the flash, I ran over to the left of the rock to illuminate that with an LED flashlight. Then I switched my flashlight to a red light, then ran behind each of the two people, backlighting them. And I did this all in 30 seconds. In portraiture, it's usually not a great idea to make it look like plants are growing out of a subject's shoulder. I tried to get them to switch positions, but the band wanted it to look like this, saying that they wanted the image to look weird. And so it is. The band is Bloomfield Machine, and they contacted me to photograph them near Joshua Tree, California.

An advantage of night photography, I suppose, is that you get to do it in slow motion. The exposure is much longer, after all. This gives you time to move. And that's a great advantage.

When you are using a flash for event photography, you typically don't have much time. You fire the shutter, and the flash fires. That's it.

However, in night photography, where you are taking photos with the Milky Way or doing moonlit landscapes, you might have 20 seconds, 30 seconds, or a minute or more.

Despite the very long exposures, you can take tack-sharp portraits of people without motion blur (unless you want to, of course).

Sounds fun, doesn't it?

How to Pop the Flash

Because you can move slowly, you can also take the flash with you. That's right, you're going to use the flash handheld. It doesn't need to be attached to your hot shoe or triggered. You hold the flash, then simply walk over to where you want to fire it. That's it. You're like a light stand that can walk!

Holding the flash in your hand, simply walk over to the spot where you wish to light your subject. You have plenty of time, after all. Then manually fire the flash. Like light painting, you can control where the flash goes with a light modifier such as a Rogue FlashBender. Or you can simply use your hand to direct the light. This also imparts some warmth (unless your hand is as white as snow).

How Do I Control the Brightness?

You can control the brightness of the flash in two ways:

  • Turn the brightness of the flash down

  • Stand farther away from the subject

Remember that sometimes, if you use a light modifier, that can dim the brightness of the light somewhat.

What Are the Advantages of Using a Flash Instead of a Flashlight?

This is a one-minute exposure. Yet, the parts of the subjects that the flash has illuminated are very sharp. You'll notice that the darker side of their faces is slightly blurry. This is because the flash has not illuminated them directly, so you can see some blur from them standing still for a minute. The band asked me to illuminate them like this because they liked the weirdness of it.

Getting Rid of Blur

You can light paint subjects with a good-quality LED flashlight, of course. Or you can light subjects with a good-quality LED light panel. Night photographers typically use one of these two lighting techniques when they are doing astro-landscapes, moonlit nightscapes, abandoned locations, and more. And these all work great. However, they are not as good at freezing a subject in place.

It turns out that a flash is fantastic for just such an application. And most of us already have a flash. If we don't, we can certainly purchase a decent one for very little money. Your camera manufacturer probably makes some high-quality flashes. If not, you can purchase decent flashes from Yongnuo, Godox, Neewer, Profoto, and others.

Again, the parts where they are illuminated by the flash are nice and sharp, while their darker sides are slightly blurry due to movement from the 30-second exposure.

A Flash Is Easy to Use

Almost everyone knows how to use a flash. Many cameras have pop-up flashes. Many mobile phones use flashes. Press a button, and pop! The light goes off.

I'm going to share several examples of how I quickly showed people how to take a photo of me while in the field. I'll tell the stories behind them as well, which will illustrate how easy this was to do.

Behind the Scenes for Star Trek 60: DarkSky International's Capture the Dark 2026 Photo Contest

DarkSky International's Star Trek 60 photo contest was a special pop-up mission within the larger Capture the Dark global photography contest. The contest tasked participants with heading outside under a star-filled sky and capturing a photo of themselves or their "crew" performing the iconic Vulcan salute that Spock made famous.

I found out about this contest shortly before the deadline. I rushed out with my wife to take photos for this. I imparted to her what I was going for and approximately where to stand. I also mentioned how to hold the Rogue FlashBender and position her hand so that there would not be too much light spill on the ground.

By the way, I won third prize in the contest for this category. Being an enormous "Star Trek" fan, I cannot tell you how much this makes me smile.

You could say that what I wrote is more of a demand and less of a request. But sometimes, there is only so much room to write when you are sitting down and writing all your letters backward with a large flashlight. Since I only had one chance to nail the letters correctly, I spent part of my time in the shower practicing how to write backward, also practicing clicking the flashlight on and off for each letter while pretending to hold the flashlight in my hand. 

I'll share a personal photo that I created with Lisa helping out on New Year's Eve at our house in Los Angeles.

I asked her if she could pop a flash by bouncing it off the area where the wall and ceiling come together. She assumed I was going to create a photo to post for New Year's Eve.

First, I set the camera on a tripod and began the exposure. I used a handheld LED flashlight to "light write" this message while the camera's shutter was open for this 60-second-long exposure. I had to write it backward with the flashlight so it would appear correctly to the camera. I did this only once.

Then Lisa popped an off-camera flash to light me and the room, not realizing what I had written.

I then called her over to have a look at the camera, saying, "Let's see how this came out!" She saw my "LISA MARRY ME" message and was quite surprised! She said yes. I joked and said she had to "light write" her answer. But no, not really.

I never showed her how to pop the flash or even adjust the brightness. It was easy enough that just saying, "Aim it at the corner where the ceiling and the wall come together," was enough to create a pleasing image.

What I Use for a Flash

 

My go-to flash is an old, discontinued Nikon SB-600 AF Speedlight, which I've had for at least twenty years. It's a relatively bright flash. And it's also durable. I've dropped it from about four feet onto a concrete floor. And no, I wasn't testing its durability for Fstoppers. Sometimes, I just drop things. And sometimes, as in the case of my flash, I do it several times. No cracks, no nothing. It just keeps working.

They sell used for under $50.

Want to Add Color?

If you want to add color, you can easily place gels in front of the flash. You may add creative colors if you want. Or if, for some reason, you are shooting with a very cool white balance, you could use something such as a CTO (Color Temperature Orange) gel to warm the subject. Gels allow photographers to intentionally introduce vivid colors into a photo.

A blue gel (CTB) can add a cool, moody tone to shadows, while vibrant hues like red, purple, or magenta can be used as key lights or to illuminate backgrounds for a striking, futuristic look.

Other Techniques for Night Portraits

There are other techniques for photographing night portraits, such as combining low- and high-ISO photos, standing very still, and more. I teach many of these in my night photography workshops. But I thought I'd start with using flashes because they are easy to use and get great results without much fuss.

Ken is a night photographer with four books of night photography of abandoned locales. His images have been in National Geographic Books, Omni, LA Times, Westways, & elsewhere. Ken had exhibits at La Quinta Museum & Hi-Desert Nature Museum in CA. He loves teaching creative weirdos about night photography in his workshops (see website).
