Rim light – the simple lighting technique behind dramatic photos

Dramatic lighting with rim light

Not all photos have or need rim light, but when it is used, it really brings an image to life. It’s dramatic when used as the only light, but can be a subtle addition to an image when used in conjunction with other lighting.

What is rim lighting?

The first thing to know about rim lighting is that it’s not a specific type of light, as in gear. It’s a way to light your subject from behind and you can use any type of light as a rim light – both natural light and flash.

Because rim lighting is a form of backlighting, it’s any light source that’s used predominantly from behind the subject, but not necessarily directly behind. So, while it is backlighting, it’s more than that, it’s a specific type of backlighting.

You can see rim light in a photo by looking at the edges of the subject, the outline, hence the name rim light. When the edges are clearly lit, rim light has been used.

What is the purpose of rim light?

The main purpose of rim lighting is to separate your subject from the background, particularly when the background is the same color as the subject.

It adds depth and interest to an image.

How to create rim light in portrait photography

As I mentioned earlier, you don’t need any specific type of gear to create rim light. Any light can be used and, in the case of flash, any type of modifier can be used, depending on:

  • Whether you want the rim lighting to be hard or soft light
  • How big you want the rim light to be (to cover just head and shoulders or full body)

With rim light vs without rim light

These two photos show how rim light adds depth and interest to a photo, and also separates the subject from the background. On the left, although she’s in shadow, the last rays of the setting sun are just reaching her. On the right she’s completely in shadow with the sun’s rays blocked by the rock.

Rim light set up

If using off camera flash, move your lighting to where it will create a good rim of light on your subject. If using natural light, you’ll need to move your subject to the ideal position.

Either way the rim light can be positioned:

  • Directly behind your subject
  • Or behind and off to the side

To get a nice rim of light behind and just around the one side of the subject, the light should be:

  • Behind and slightly to the side of the subject
  • Higher than the subject
  • Angled down at 45 degrees

It helps to think of light placement in terms of a clock face. So, for the above scenario, imagine a clock with:

  • Your subject in the middle
  • The background at 12 o’clock
  • You at 6 o’clock
  • The rim light is at 2 o’clock

 

Rim light separates subject from background

What is the minimum number of lights required for a rim lighting setup?

The great news is that you can create a rim lighting set up with just one light for a highly contrasty low key image like the one above. It all depends on:

  • The look you want to go for
  • The amount of available light
  • How you use the light

Using rim light as a hair light

In this two light set up, the sun on her hair is creating both a hair light and rim light, while she is lit from camera left by off camera flash.

Alternatively, you can use two lights. With flash you can set up a key light to light your subject, then add another behind the subject as a rim light to separate them from the background.

But don’t think rim lighting is just for flash photography. You can very easily use just natural light.

Natural light vs OCF light with rim light

I used off camera flash to light the dancer from camera right and used the setting sun for rim light on the first image. For the second image I used natural light only. You’ll notice that she’s largely in shadow, but is subtly rim lit by the setting sun.

And you can take it a step further by adding a fill light as well to fill in the shadows. This is a typical three point lighting set up.

Again, this is possible with just natural light if you use a reflector as a fill to bounce light back into the shadows.

By adding a hair light you could create a four point lighting set up. Or add another rim light to the other side of the subject for a five point lighting set up. The list goes on.

OCF lighting setup using rim light

Lighting can be as complicated or as simple as you want. As I said, it all depends on the light you have to work with and the look you want to create. The most important thing is to start off simply. If possible, rather use 2 lights to create the look you want than 5.

However, to answer the question, to create rim lighting set up, you actually just need one light source.

What to watch out for with rim light

As we’ve seem rim light can really make a photograph stand out, but it’s not just a matter of putting your subject in front of a light. We’ll look at 4 mistakes to avoid when setting up rim lighting:

  • Blown out highlights
  • The wrong background
  • Unwanted flare
  • Rim light spilling onto the subject’s face

1. Blown out highlights

The lighter the subject, or part of the subject that’s rim lit, the easier it is to blow out the highlights.

This is particularly problematic if your rim light is brighter than your key light (the main light on your subject) and occurs more with natural light photography.

It stands to reason that if the light is behind the subject, the side facing you will be in shadow and therefore darker. If you expose for the light behind, the subject will be underexposed and if you expose for the subject, the rim lighting will create blown out highlights on your subject.

There are 2 solutions:

  • Underexpose the image to preserve the highlights and then bring up the shadows in post production
  • Illuminate the subject by bouncing light back into their face with a reflector or with off camera flash

Overexposure and underexposure tips

Getting started with off camera flash

Controlling exposure of rim light

Both these images were lit with natural light only and no reflector, other than the light colored floor. The first image shows blown out highlights on her hair, because the exposure was set for her face which was not lit. For the second image I underexposed and adjusted in Lightroom.

2. The wrong background

The color of the background will affect the visibility of rim light on the subject – dark backgrounds show rim light, but light backgrounds don’t. After all, white on white doesn’t stand out.

Background affects visibility of rim light

3. Unwanted flare

Flare in photography is very popular, so much so that many photographers add flare in post production. That’s great if you want flare, but if you don’t, you need to be aware of where your light is when capturing a scene.

If the light is in shot or only just out of shot, it will be visible in the image as lens flare.

Avoid rim light flare and spill onto subject

This scene was lit by natural light, with off camera flash as rim light. Both images show flare on the right from the rim light. In this instance it was created intentionally for a little atmosphere, but to avoid it I could have shifted my camera angle slightly to the left . For the right image I changed position slightly more to the right to add more flare.

On the other hand, the dancer also changed her head position slightly, turning more to camera and catching the light on her cheek. This small patch of bright light on her face is distracting.

4. Rim light spilling onto the subject’s face

If you’re not careful you can easily end up with too much light spilling onto your subject.

Rim lighting should highlight the edge of the subject and taper off fairly quickly into just a kiss of light on the subject. More than that and it will become distracting, rather than enhancing, as you can see in the image above.

  1. Instead of a comment, I have a question. I’m preparing a photoshoot with my niece and her husband during her 8 month pregnancy. Would you possibly have any suggestions. If I’m not asking for too much. Thank you

  2. Hi Jane,

    Yes for sure: “our portrait photography lighting tips have helped me to understand how to use rim light,”

    Thanks for your site and the way you’ve organized it – you seem to not just do a tutorial but also include us as assistants during shooting while explaining in the image’s captions: very live on the ground.

    *As I’ve been learning camera and gear, you too, seem confirm as other sources: “Angled down at 45 degrees” is the general angle for the softboxes facing subject and same angle on either side of subject…generally. A reflector for under chin, or whole body would be the same angle also? That’s “butterfly” lighting?

    I’ve invested in softboxes, 9ft x14ft. background, triggers etc., and bluetooth for phone to DSLR (canon connect). Anything on full-length portrait lightning (like this post) is so helpful in the “spare room” studio… Thx, Frank

    Thx.

    1. Hi Frank

      Thanks for your comment – so glad you found it helpful.

      The lighting you describe using the reflector under the chin is clamshell lighting – it’s butterfly lighting with an extra light source. Here’s how… Position your key light for a butterfly lighting pattern and then the fill light (either a reflector or second light) below the subject pointed upwards to fill in the shadows. Here’s a tutorial I wrote on butterfly lighting – https://thelenslounge.com/butterfly-lighting-pattern/
