Low-key photography is widely used and it's not only about pictures of something on a black background. Only quite low-grade low-key photographs are merely showing an object on a black background. Low-key photography was inspired by earlier forms of art. Back a few hundred years ago during the Baroque period, the painters started using different techniques creating high contrast and adding more details to the main subjects of their paintings. The style was called chiaroscuro. I would say the whole way of creating high contrast paintings with lighting only in the foreground was invented by Caravaggio.
This way the contrast lighting affected the composition and all of the shadows were blended together in big dark shapes. Later hundreds of painters were influenced by Caravaggio and they used this technique with the dark shadows and background and most of the details were focused on the foreground. I love low-key photography because it's also a way to focus all your attention on the main subject. You can do low-key photography not only in the studio but anywhere where you can see or create a strong contrast between the focus points of your composition and the surrounding areas. Since low-key photography is about having big dark areas of shadows with the minimum details in it but not only putting a subject in front of a black screen.
This guide will tell you what low-key photography is, and will help you to get some insights into how to use it.
Getting to know low key photography
It's good to learn all of the art techniques to have a greater understanding of how to create a photograph. Here I collected some information on what to pay attention to when doing low key photography
The overview of low-key photography: why it's important to learn it and how it will help to improve your photography skills?
The overview of Low-key photography, and its importance
Low-key photography is basically the way to photograph your subjects highlighting only some parts of an image that are more important. It's a way to add some mystery to your photograph and hide the rest of the details in the darkness. Another type of low-key photography involves using mostly black colours to show mainly the reflections of light on the black. It might look dramatic and mysterious but I think it's too simple to make a portrait in a black outfit on a black background and then call it a day. What seems more interesting is to create photographs where darkness is used as a part of the composition but not only surrounding a subject in the middle.
To do this type of photography you need to learn how to see this contrast and how to show it in your photographs. Try to also remember to keep your highlights not overexposed because they will always look unnatural. And you also need to learn how to use light as your artistic tool.
I do not recommend doing low-key photography for the sake of doing low-key photography itself. Because there should always be an idea beforehand. And then the way to depict it. Otherwise, it's easily seen when the technique is used without a certain purpose.
But I often create something similar to low key because I had such an Idea without any aim to create images in this style.
Low-key photography is really important to learn since it helps to master the design of shapes (the shapes of shadows) and the ways to direct your lighting on the important parts of your image. It helps to stylise your image more and leave it to the viewer to decide what is hidden in the darkness.
How to do low-key photography.
With artificial light
One of the best ways to create a strong low-key image is to highlight only the main subjects of your composition in the foreground with a flash or a lantern. You can easily achieve a detached and isolated look by creating this kind of photography. For that, you need to use strong lights and set your exposure to capture well all the details in this spot of light. In most cases, the rest of the image should appear black. Another way to create mysterious images with still objects is to use light painting. Try to put your camera on long exposure at night and using a lantern highlight the parts of this object that you want to be seen in the photograph. To achieve the desired effect you need to keep your exposure to about -2 - -3. And there should be strong contrast between the area lit with the lantern and the underexposed part without light.
With natural light
To create low-key photographs with natural light you need to search for a strong contrast between the highlights and shadows. It might be very difficult to find when the weather is cloudy. You need to walk a lot around your subject trying to find the best angle. To get more shadows in your frame
Your aim is to hide the details in the shadows. So in post-processing, you can darken them almost to pure black. To achieve that and reduce the number of details in the frame I also often move the point of black on the curves higher. That is also similar to how dark shadows appear on film if you shoot on a bright sunny day.
As well as just darkening the shadows, you can use the adjustment brush tool and blend any unneeded details with the bigger shapes of the shadows. For example, in the photograph below I had some texture on the ground that was taking away my attention. It was not needed there at all. So I decided to make it the same black as the shadow on the wall and it blended perfectly.
My Low-key photographs
Here I've collected some of my low-key photography where most of the scene is absorbed by the darkness.
Low key photography as a way to convey your idea
I want to encourage you to not try to use all of the dynamic range your camera has to offer and to try to shoot things objectively. There's nothing bad in not having all these details in shadows since it's your perception of the world, not a copy of it. By allowing the shadows to get lost in the darkness you give the viewer the freedom to wonder when they're looking at your photos. You're leaving some space for mystery and of course, giving more visual power to the main subject over everything else. Try to let the darkness be a part of your subject and of your composition and it will help you to get a better understanding of light in photography.
