In our second tutorial on direction of light we are looking at how to use side light. Specifically, where to find it or how to create side lighting, as well as when and how to use it.
But first… What is side lighting?
Side lighting is quite literally what it says on the tin. It’s lighting a subject from the side of the subject. Obviously, this is quite a broad area, but we’ll get into the angles of side light later.
To work through how to use side light, I’ve divided my tips into three parts:
1. Why use side lighting?
- Defining shape and dimensions
- Creating mood
- Exaggerating depth
2. Tips on making the most of side light
- Controlling the background
- Adding drama to an image
- Instilling serenity in an image
3. Actually using side lighting
- Using the angles of side light to define subjects
- Side lighting in portraiture
Shot with natural light on an overcast day, after the sun had slipped below the horizon. Therefore there are no shadows.
1. Why use side lighting?
Before we get into how to use side light, let’s start with why you would want to use it in the first place.
Defining shape and dimensions
We are used to defining the shape of an object by its tonal range of light to dark. This is how our brain deciphers what we see around us.
When lighting an object from the side, there will be a light side and a dark side to the object. These shadows define its three dimensional structure, which then persuades our brain to see the flat image as three dimensional, because we can see its shape.
So, REASON NO. 1: use side light to show objects in an image as three dimensional.
Shot just before the sun set. The low angled sun shining from the side creates shadow on her cheek closest to camera and a shadow from her nose to her cheek. This adds three dimensional form to the image. It defines the shape of her face.
Creating mood with side light
Mood is affected by the type of light in an image and, as side light adds texture to a subject (more on this in a moment), we need to consider what feeling we want to convey with the type of light that’s visible in the shot.
When we have a a clear blue sky and bright sunshine, shadows are crisp and clearly defined. This is referred to as hard light. The harder the light, the greater the contrast between light and shadow.
On an overcast day, shadows are faint and fuzzy and this we refer to as soft light. If you live in the UK, you’ll also be used to non-existent shadows! It doesn’t get any softer than that.
To manipulate the tonal range (range of light and dark) in the same way as clouds vs clear sky affects shadows, we have a few options.
If we don’t want dark shadows, we can use a reflector on the shadow side of an object to bounce light back in and so lighten the shadows. Alternatively, we could use a diffuser between the light and the subject to partially block hard light hitting the subject.
REASON NO. 2: light is everything to photography, the type of light and how you use it dictates the mood of the image.
Speaking of texture
Side lighting is a favourite of landscape photographers and wildlife photographers, as the direction of the light brings out textures in the subject. Texture is an essential consideration of well thought out composition. Light skimming across the surface of a rock face will cast all the nooks and crannies into shadow.
Equally, side light on a fluffed up bird having a bath will highlight the ruffled feathers and accentuate any flying water droplets.
In portraiture, side lighting adds mood to an image. It also defines the subject’s face and adds depth.
Using side lighting in the golden hour makes the most of the low angled sun for texture and mood. This is the best time to use side lighting when photographing with natural light outdoors.
Because side light exaggerates textures by creating shadows it’s very effective in black and white photography.
REASON NO. 3: texture makes an image palpable and interesting. The viewer feels that they are there, seeing the subject with their own eyes.
The side lighting in this shot emphasises the texture of the model’s top, as well as the blurred reeds behind her. The color of her eyes comes alive, because of the light coming from the side.
In photography, most of the time we’re working to separate our subject from the background, to make it stand out and draw the viewer’s eye.
Side light on the subject exaggerates the depth in an image by separating the subject from the background. It does this by defining the contours of your subject.
The subtle glow around the subject is similar to, but not as defined as when lit from behind. Side light is enough, however to create a sharp outline of the subject. This defines its shape and gives a three dimensional feel to the photograph.
The separation is increased if the light hits your subject only and not the background. If the background is in shadow and the subject is in the light, because the eye is always drawn to the lightest part of an image, the viewer will automatically be drawn to the subject.
REASON NO. 4: side light separates your subject from the background and draws the viewer’s eye.
The woodland behind the boys is in shadow and, although busy, is blurred, so is not distracting. The boys are lit by a break in the tree canopy allowing light in. This isolates them from the background, so our eyes are drawn straight to them.
2. Tips when using side lighting
Speaking of backgrounds, that leads us on to how to make the most of side lighting.
To add to the separation and keep attention on your subject, you need to ensure that the background is as uncluttered as possible. Physically uncluttered, especially by light coloured objects. As mentioned above, our eyes are drawn to the lightest part of an image first and then any other light patches.
If there’s a lot going on in the background, using a low aperture is one of the most popular methods for blurring it. A blurred background is less distracting and again helps to isolate the subject.

Add drama to a photo
For a more dramatic image, expose for the lit side of your subject, even if you’re photographing from the shadow side.
If the light is too intense it will make the highlights too obvious, which will draw too much attention away from the subject. By exposing for the lit side, the shadows will automatically be darker and it’s this contrast that adds drama to the image. As mentioned before you can lighten the shadows by bouncing light back in with a reflector, or with artificial light.
The closer the light is to the axis of the lens, the flatter the light will be – go wide for texture, drama and definition. In other words, the more to the side the light is, instead of being near you, the more dramatic it will be.
Imagine your subject is standing in the middle of a clock, facing you standing at 6. If the light is at 6 as well, it will hit your subject flat on, front lighting it, and there will be no shadow. No shadow equals no definition and a potentially dull image.
Add serenity to a photo
Do the exact opposite for light, airy, peace and serenity. Expose for the shadows.
This will blow out the highlights and create a high key image. If the shadows are soft (as we mentioned at the beginning), the image will be peaceful.

3. Using side lighting angles to define subjects
Now we’re ready to get into the techniques of using side light. This is about defining our subjects with side lighting, regardless of whether it’s natural light or artificial light.
Wether you’re photographing landscapes, wildlife, portraiture or street photography, the angle of the light is key.
Defining subjects using artificial light as a side light
If you’re using artificial light, move the light around to either 4 or 8 (on the clock) and you’ll see the shadows forming on your subject.
If the light is at either 3 or 9, you’ll be at the extreme end of side lighting. Every little bump or dent on your subject will be accentuated by the light skimming across it.
Defining immovable objects using the sun as a side light
The same thing applies if you’re using the sun to light your subject.
Obviously, you can’t move the sun, but you can either wait for the sun to move through its natural arc if you can’t move your subject (mountains, buildings etc).
Defining moveable objects using the sun as a side light
If your subject can move, position it according to the placement of the sun.
Of course, you’ll need to bear in mind the background, so it might not always be possible. In which case, come back at a different time of day when the sun is in a position to shoot a better background.
Side lighting angles for portraiture
When lighting people from the side, at about 45 degrees (i.e. half way between 3 and 6, or between 9 and 6 on the clock), it’s worth knowing that photographing them from the shadow side (short lighting) or from the lit side (broad lighting) will change their look.
This is why lighting is so exciting and so important in photography! Without light there is no photography. Mastering light leads to excellence in photography.
