High Key Photography in Natural light – A Step by Step Guide
In one of my posts, I have explained the technique of low key photography in natural light. In this post I am going to give you a step by step guide for high key photography in natural light. High key photography is basically eliminating shadows by letting more light into the camera. So majority of the tones in the photograph are in the highlight region. This gives the photograph a positive mood and a sense of calmness. You might have noticed high key photography especially in kids’ photographs, model shoots, and product photography. The high key effect highlights the subject well which is why it is widely used in commercial shoots. However, studio lighting setup is usually used for such kind of shots since we can control the artificial light. But that’s not the case with natural light. We cannot control the natural light. High key photography technique in natural light is simple. In this post, I am going to help you to learn this technique.
The ‘High key’ in high key photography
Before going into the technique, let me explain what does high key mean. It will help you to understand this technique better. Usually, the key tones in any image are the midtones. So, high key means we are mapping the key tones or midtones to a higher level. I.e. we are brightening the key tones — as simple as that. So, normally, the highlight tones become whiter and the shadow tones are mapped to brighter tones, too.
This high key photography technique is basically the opposite of the low key photography in natural light. So, all you need to do is to do the opposite of what I mentioned in my post on low key photography. Anyway, below is the step by step guide for high key photography in natural light.
Step 1: Find a non-distracting background. That means the background tones should be continuous. For example, the background should not have deep shadow regions. If you can find a background which has more bright tones, then you can easily make a high key photo. However, sometimes, you may not find a background which has only bright tones. There will be some neutral tones or dark tones in the background since we are dealing with natural light. But, do not worry. You can fix them later during post processing.
Step 2: Overexpose the background. Once you find a suitable background, you need to overexpose it by 1 or 2 stops. But make sure there won’t be any blown out highlights when you over expose the scene.
Steps to over expose the background
Step i: Switch to matrix metering mode and point your camera to the background. You can either use aperture priority or manual mode.
Step ii: If you are using aperture priority mode, after setting the aperture, change the EV value to +1 or +2 (in canon cameras) or -1 or -2 (in Nikon cameras) to overexpose the background.
If you are using manual mode, set your desired aperture; ISO; and shutter speed so that the EV marker blinks at +1 or +2 depending on how much you want to over expose.
NOTE: When you overexpose, if the shutter speed is very slow, you should use a sturdy tripod to prevent blurry shots.
So the idea is to make the bias the exposure to +1EV or higher. There is no standard aperture, shutter speed, or ISO setting in high key photography technique. All you need to do is to evaluate the exposure in such a way that there should be more light letting into the camera.
Step 3: Check the histogram and make sure you got the shot. Don’t let the LCD of your camera fool you. You may not see a proper result when you review the shots in your camera. So, how do you know you got the shot you wanted? Thanks to the histogram. After taking the shot, switch to the histogram view mode to review the shot (Refer your camera’s manual for this). The histogram of a high key photograph shifts to the right. This will help you to take high key photograph in the camera itself.
Things you should keep in mind before taking a high key photograph
- There should not be any blown out highlights or deep shadows. If it is unavoidable, it can’t be made into a high key photograph.
- Not every scene can be turned into a high key photograph. You cannot make any scene into a high key photograph by over exposing it. So, you should choose a scene that can be converted into a high key image. How? High key is basically brightening the midtones and shadows. So you should make sure the midtones and dark tones are not dominating the scene. If it does, then over exposing the scene will not make it a high key image. So, high key photography is not just overexposing the shot; it is about the exposure and the lighting. A low contrast scene can be turned into a high key photograph with this technique.
- Over expose the shot to +1, +2, and +3 EV. In this way, you don’t have to rely on any image editing software to fix it. That is, even if you find that you get a high key image when you over expose it to 1 stop higher than the standard exposure, take shots with +2, +3 EV as well.
- The final image will be flat, and less saturated. High key images are less saturated and are flat or low contrast. So, don’t panic. This is because in high key photograph, most of the tones are brighter than the midtones (higher than128 in histogram).
- If you see that the tones are inconsistent, you can fix them later in post-production.
Some people may not find this a high key photography technique. But this is what you can do in natural light since you can’t control the lighting. This technique is not about just over exposing a scene to make high key photograph. It’s about finding the light and then over exposing it. Otherwise I would have told you to take a shot and I hope by this tutorial you know what a high key image is and how to evaluate the natural light for making high key images.
