Everyone raves about golden hour (and for good reason!) but the magic doesn’t stop when the sun goes down. As soon as the sun sets, stick around for blue hour. Once golden hour fades away, a soft blue light will fill the sky, creating an atmosphere that’s just as gorgeous as its sunnier counterpart.

Read on for everything you need to know about this magical time, including ideal camera settings and how to nail beautiful blue hour shots every time.

When blue hour happens

Just like golden hour, blue hour happens twice a day – in the morning, before sunrise and in the evening, right after sunset.

Similarly to golden hour, time is not exactly on your side – you may have as little as twenty minutes in some locations!

To make the most of this brief window, you have to plan ahead and know your camera settings so you can take full advantage.

Why blue hour is the best

During blue hour, red light passes through space while blue light is scattered in the atmosphere. This result creates a cool, peaceful photography lighting that’s perfect for portraits, landscapes, you name it. And because there’s still just enough light in the sky, you can still capture the details of your subject, and the moody atmosphere makes for some seriously dreamy portraits.

Blue hour is also the only time of the day where you have the necessary lighting to capture the contrast of the sky with warm artificial lights, creating a gorgeous aesthetic that many photographers unfortunately overlook!

How to make the most of blue hour

Despite its name, blue hour lasts for less than an hour, so it’s crucial to be quick with your camera settings.

Setting your f/stop to 2.0 and work your way up towards f/5.6 (if the light allows) for family or group shots. For a crisp focus on your subject, start your minimum shutter around 1/250.

The light during blue hour changes quickly and tends to be the brightest in the first few minutes, so compensate with a wide ISO range of 500-1500. A white balance between 5000-7000 will also help you capture the soft light.

Just like every other photo session, preparing for blue hour also involves having some go-to poses and prompts. The Unscripted App offers over 1,400 free poses and prompts that you can save for your future photo sessions. And bonus: the app is also constantly updated, so you’ll never run out of ideas and inspiration.

No, blue hour generally lasts 20 to 30 minutes just after sunset and just before sunrise.

What is the difference between blue hour and golden hour?

The golden hour occurs just after sunrise and before sunset, when the sun is low on the horizon, creating that signature warm glow. The blue hour arrives shortly before sunrise and after sunset, when the sun's position just below the horizon produces those cooler tones.

What is the color temperature of blue hour?

The light has a color temperature in the blue hour between 9000 and 12000K.

Do you need flash during blue hour?

Some photographers use off-camera flash to illuminate their subject and create a balance between the subject and the background sky.

What are the ideal camera settings for blue hour?

Generally, you’ll want to set your f- stop to 2.0 and start with a 1/250+ shutter speed. You have some wiggle room with your ISO (between 500-1500) and a white balance between 5000-7000K.
