Photography and Filmmaking: Why Lighting Matters More Than the Camera
It is very easy to become obsessed with cameras.
Which camera has the largest sensor? Which lens is sharpest? Should I be recording in 4K, 6K or 8K? How many stops of dynamic range does the latest model offer? Do I need another lens?
All of these things have their place, but after many years of taking photographs and making videos, I increasingly come back to a much simpler conclusion:
A good camera cannot rescue bad lighting nearly as effectively as good lighting can improve an ordinary camera.
Get the lighting right and a surprising number of other things begin to fall into place. Faces look better. Colours become richer. Autofocus tends to work more reliably. Noise becomes less noticeable. Backgrounds gain depth. Products acquire shape and texture. Even relatively inexpensive cameras and phones can produce remarkably professional-looking results.
Lighting is therefore not merely something added after choosing the camera.
Lighting is part of the picture itself.
In this article, I want to explore some of the basic lighting principles and practical setups that work particularly well for photography, video production and filmmaking.
Start by Looking at the Light, Not the Camera
One of the most useful habits a photographer or filmmaker can develop is to walk into a room and look at the light before taking the camera out.
Ask:
- Where is the light coming from?
- Is it hard or soft?
- What colour is it?
- How bright is the subject compared with the background?
- Are there unwanted shadows?
- Is the subject separating clearly from the background?
- Could I improve the scene simply by moving the subject?
Sometimes moving somebody by a metre can make more difference than changing a £1,000 lens.
That is the fascinating thing about lighting. Much of the improvement costs nothing at all.
The Four Things I Usually Look at First
Before discussing individual lighting arrangements, it helps to think about four basic properties.
1. Quantity of Light
The obvious question is simply:
Is there enough light?
Modern cameras can operate in remarkably poor conditions, but just because the camera can produce an image does not mean it will produce the best image.
If there is too little light, the camera may need:
- a wider aperture;
- a slower shutter speed;
- a higher ISO;
- or electronic amplification.
Higher ISO can mean additional noise and loss of detail.
Adding more light frequently gives the camera a much easier job.
2. Quality of Light
Light can be hard or soft.
A small light source produces relatively hard shadows.
A large light source produces softer shadows.
This is why a bare LED lamp can produce quite an unflattering face while the same lamp shining through a large softbox can look excellent.
Interestingly, the Sun is physically enormous, but because it is so far away it behaves like a relatively small light source in the sky.
That is why direct sunlight can produce very strong shadows.
An overcast sky effectively becomes one enormous diffuser, producing much softer illumination.
For portraits and interviews, soft light is often extremely useful.
3. Direction of the Light
Direction changes how we perceive shape.
Light coming directly from the camera tends to flatten the subject.
Light arriving from one side creates shadows that reveal form and texture.
Backlighting can separate a person from the background.
Lighting from underneath can make somebody look distinctly sinister—which is one reason it has been used so effectively in films.
Simply changing the direction of a lamp can completely change the emotional character of a scene.
4. Colour of the Light
Not all white light is actually the same colour.
A traditional tungsten lamp appears warmer than daylight. Daylight itself changes throughout the day.
Lighting equipment is commonly described using colour temperature.
Typical values are approximately:
- Candlelight: around 1,800 K
- Traditional tungsten lighting: around 3,200 K
- Daylight: around 5,500-6,500 K
Many modern LED lights can be adjusted across a range of colour temperatures.
The important thing is consistency.
If one side of someone's face is illuminated by daylight through a window while the other is illuminated by a warm household lamp, the camera can struggle to make both look natural.
Sometimes mixed lighting is deliberate.
Frequently it is simply distracting.
Setup One: The Simplest Light of All — A Window
Before buying studio lights, try using a window.
A large window can make an excellent soft light source.
Place a person near the window, but rather than having them stare directly towards it, turn them slightly so that the light comes from approximately 30 to 45 degrees to one side.
Immediately you begin to see modelling across the face.
One side is brighter.
The other has a gentle shadow.
The face suddenly looks three-dimensional.
Move the person closer to the window and the light becomes stronger.
Move them further away and it becomes weaker.
Add a white board, sheet of foamboard or reflector on the opposite side and some of the window light can be bounced back into the shadows.
You have just created a surprisingly sophisticated portrait lighting arrangement without switching on a single studio lamp.
Setup Two: One Light Can Be Enough
If I could encourage somebody beginning video production to learn one lighting arrangement, it would be the single large soft light.
Place a softbox roughly:
- 45 degrees to one side of the camera;
- slightly above eye level;
- angled down towards the subject.
Do not automatically place it directly in front of them.
The slight side angle produces natural shadows and gives the face shape.
The result can be extremely effective for:
- YouTube videos;
- online teaching;
- interviews;
- presentations;
- corporate video;
- portraits.
And there is an important practical lesson here.
Move the light before buying another light.
People often try to solve lighting problems by adding equipment when changing the position of one lamp would work better.
Setup Three: The Classic Three-Point Lighting System
One of the best-known arrangements in filmmaking and video production is three-point lighting.
It consists of:
- the key light;
- the fill light;
- the back light or hair light.
It remains useful because it demonstrates three separate jobs that lights can perform.
The Key Light
The key light is the principal source.
It normally provides most of the illumination on the subject.
A typical starting position is about 45 degrees to the side and slightly above the subject.
However, this is a starting point rather than a rule.
Move it around.
Watch what happens to the shadows.
The Fill Light
The key produces shadows.
Sometimes we want those shadows, but sometimes they are too strong.
The fill light is positioned on the opposite side and is normally less powerful.
Its job is not necessarily to remove the shadows completely.
It simply controls how dark they become.
This is an important distinction.
Completely eliminating every shadow can leave a face looking flat.
A little shadow usually creates shape.
The Back Light
The third light is positioned behind the subject and directed towards them.
It might illuminate:
- the hair;
- shoulders;
- edge of the body.
This produces a subtle rim of light.
Its purpose is separation.
Without it, somebody wearing dark clothes against a dark background can almost merge into the background.
Switch on the back light and suddenly the outline becomes clear.
It is a small change that can make footage look considerably more polished.
You Don't Necessarily Need a Fill Light
There is another useful lesson here.
A lighting setup may be described as three-point lighting, but that does not necessarily mean you need three lamps.
The fill can simply be a reflector.
A piece of white foamboard can bounce some of the key light back towards the subject.
You can also use:
- a photographic reflector;
- a white wall;
- white card;
- a sheet;
- even a large piece of paper for small objects.
Learning to control existing light is every bit as important as learning to add more lights.
Negative Fill: Sometimes We Want More Shadow
Here is an interesting technique that is often overlooked.
Suppose you are photographing someone in a bright white room.
Light is bouncing from every wall and filling all the shadows.
The resulting image may look rather flat.
Instead of adding light, place something black beside the subject.
A black curtain, photographic flag or sheet of black foamboard absorbs some of the reflected light.
The shadow side of the face becomes darker.
This is called negative fill.
It demonstrates an important principle:
Lighting is as much about removing light as adding it.
Setup Four: A Simple Interview
Imagine recording an interview.
Instead of placing your subject against the wall, move them several feet forward.
Already the picture improves because the background can fall slightly out of focus.
Now position:
Key light:
Large softbox approximately 45 degrees from the face.
Fill:
White reflector on the opposite side.
Back light:
Small LED above and behind the subject.
Background light:
If available, place a small additional lamp behind the subject aimed at something interesting in the room.
Perhaps illuminate:
- a bookshelf;
- scientific equipment;
- a musical instrument;
- a plant;
- a piece of machinery.
The background now has several layers.
Suddenly the shot has depth.
That is often one of the differences between footage that looks like "someone sitting in a room" and footage that begins to look deliberately produced.
Lighting a Background Is Often Forgotten
People understandably concentrate on lighting the person.
But filmmaking is about the entire frame.
Consider the background separately.
Is there a dark corner?
Could you illuminate an object?
Could a practical lamp appear naturally in the shot?
Could coloured lighting subtly distinguish the background from the subject?
Even something as simple as putting a table lamp in the background can create a useful pool of warm light.
You are effectively creating layers:
Foreground — subject — background.
That creates visual depth.
Setup Five: Product Photography
Lighting becomes particularly interesting when photographing objects.
Consider something simple such as a camera, piece of scientific apparatus, watch or electronic device.
Put a light directly above the camera and the object may look surprisingly flat.
Move a large softbox to the side and suddenly:
- edges become visible;
- textures appear;
- curves become clearer;
- lettering gains definition;
- the object appears more three-dimensional.
You can then introduce white cards to reflect light onto particular areas.
This is almost like painting with light.
Move a small reflector and watch a highlight move across the product.
It is remarkably instructive.
Shiny Objects Need Special Treatment
Highly reflective objects introduce another problem.
You are not really photographing just the object.
You are also photographing everything reflected in it.
Try photographing:
- polished metal;
- glass;
- glossy plastic;
- chrome;
- jewellery.
A tiny lamp may create an ugly bright spot.
A large diffused panel, however, produces a broad attractive reflection.
This is why professional product photography can involve enormous diffusers surrounding surprisingly small objects.
The object is effectively reflecting the shape of the light source.
Setup Six: Macro Photography
Macro photography creates its own lighting problems.
Move extremely close to an insect, electronic component or small experiment and the camera itself can block the available light.
Depth of field also becomes extremely small.
You may therefore want to use a smaller aperture, which in turn requires more light.
Possible solutions include:
- LED panels;
- diffused flash;
- ring lights;
- small reflectors;
- flexible LED lights;
- translucent diffusers.
But again, diffusion matters.
A powerful flash very close to an insect can produce harsh reflections.
A diffuser spreads the apparent source and creates much gentler illumination.
For photographing insects, flowers and small scientific specimens, this can make an enormous difference.
Setup Seven: Dramatic Lighting
Not every scene should be evenly illuminated.
Sometimes shadow is part of the story.
Move a key light strongly to one side and leave the other side relatively dark.
Immediately the scene becomes more dramatic.
This can work for:
- documentary sequences;
- film scenes;
- promotional photography;
- musicians;
- workshop footage;
- engineering projects.
Place the light almost directly to the side and you create a striking split across the face.
Move it slightly further around and the result becomes even darker.
Lighting therefore becomes storytelling.
Lighting Can Change the Meaning of a Scene
Imagine photographing exactly the same person in exactly the same room.
Version A uses:
- bright soft frontal lighting;
- bright background;
- very little shadow.
The result may look friendly, open and instructional.
Version B uses:
- a strong side light;
- dark background;
- little fill;
- perhaps a rim light.
The same person may now appear mysterious or dramatic.
Nothing about the camera has changed.
Nothing about the subject has changed.
Only the lighting has changed.
Yet the emotional message is different.
That is why cinematographers devote so much attention to light.
Outdoor Photography: You Still Control the Light
Outdoors, we cannot move the Sun.
But we can move ourselves.
One of the worst times for portraits can be around midday on a bright sunny day.
The Sun is high and creates deep shadows beneath:
- eyes;
- noses;
- chins.
Move the subject into open shade and the result may immediately improve.
Alternatively, use a reflector to bounce sunlight back onto the face.
Or use flash to provide a little fill.
Photographers sometimes describe this as "fighting the Sun", but frequently the easier approach is to work with it.
Golden Hour
The period shortly after sunrise and shortly before sunset is popular with photographers for good reason.
The Sun is low.
Light travels through more atmosphere.
Shadows become longer.
The direction of the light becomes more obvious.
The landscape gains shape and texture.
Photograph exactly the same scene at midday and again near sunset and it can look like two completely different places.
Again, the camera did not change.
The light did.
Backlighting Outdoors
One of my favourite techniques is to place the Sun behind the subject.
At first that sounds wrong.
Surely the light should be shining onto them?
Not necessarily.
Backlighting can produce a beautiful rim around:
- hair;
- leaves;
- insects;
- flowers;
- sails;
- translucent materials.
The front of the subject may then need a reflector or some fill flash.
For plants and nature photography, backlighting can be particularly effective because light passes through leaves and petals.
Filming Science Experiments
Lighting science experiments presents some interesting challenges.
The lighting should not merely make the apparatus look attractive.
It must make the result visible.
For example, when filming:
A chemical reaction
We may need strong side lighting so that colour changes are obvious.
Smoke or vapour
A dark background with strong backlighting can make tiny particles dramatically more visible.
Water
Reflections can obscure what is happening, so changing the light angle may be essential.
Microscopy or small equipment
Close-up lighting needs to reveal details without producing overwhelming reflections.
Demonstrations involving screens
We need to balance the brightness of the screen against the person presenting it.
The scientific objective should therefore influence the lighting arrangement.
Don't Forget Eye Reflections
Look at a good portrait carefully and you may see a small white reflection in the eyes.
These are called catchlights.
They may seem insignificant, but they give the eyes brightness and life.
Move your softbox slightly and watch what happens to them.
The eyes tell you quite a lot about the lighting arrangement.
In some photographs you can virtually reconstruct the studio by looking at the reflections in somebody's eyes.
The Problem of Glasses
Anyone making educational or corporate video will eventually encounter another challenge:
glasses reflecting the lights.
There are several possible solutions.
Move the light higher.
Move it further sideways.
Angle the person's face slightly.
Move the camera position.
Often only a few degrees are required.
This is where experimentation beats theory.
Rather than accepting the reflection, move things around while watching the monitor.
The Most Useful Lighting Tool May Be a Monitor
When filming myself or somebody else, I want to see the actual image being recorded.
A monitor allows me to spot:
- blown highlights;
- unwanted reflections;
- dark eyes;
- harsh shadows;
- distracting background lights;
- mixed colour temperatures.
Sometimes the problem is obvious on the monitor but surprisingly difficult to notice while standing beside the camera.
Practicals Can Be Part of the Scene
In filmmaking, a light visible within the shot is often called a practical.
This might be:
- a desk lamp;
- workshop light;
- table lamp;
- computer monitor;
- illuminated sign;
- instrument panel.
These can help make the environment feel believable.
A workshop should look like a workshop.
A laboratory should look like a laboratory.
A music studio should have its own visual identity.
Lighting can help tell the viewer where they are before anybody says a word.
You Don't Need Twenty Lights
It is very easy to watch behind-the-scenes footage from a major film production and conclude that professional lighting requires an enormous truck full of equipment.
For many smaller productions, it doesn't.
A very capable basic kit might consist of:
- one large soft LED key light;
- one smaller LED light;
- one reflector;
- a couple of stands;
- diffusion material;
- black foamboard;
- clamps.
From that, you can create an enormous number of arrangements.
The real skill is understanding what each light is doing.
A Useful Exercise: Switch Everything Off
One exercise I find particularly valuable is to build a lighting setup one light at a time.
Start with darkness.
Turn on the key light.
Look at the image.
Then add the fill.
Look again.
Then add the back light.
Look again.
Then illuminate the background.
Each time ask:
What did that light actually contribute?
If switching a light on does not improve the picture, perhaps it does not need to be there.
More lighting is not automatically better lighting.
Another Exercise: Use Only One Light
Try creating several completely different images using one lamp.
Move it:
- directly in front;
- 45 degrees sideways;
- directly beside the subject;
- behind the subject;
- above;
- below.
Then move it closer and further away.
Add diffusion.
Bounce it from a wall.
Reflect it using white card.
Block part of it using black card.
You will probably learn more about lighting from that exercise than from buying three more lamps.
Camera Technology Helps — But Light Still Comes First
Modern cameras are extraordinary.
We have:
- extremely high ISO performance;
- sophisticated autofocus;
- high dynamic range;
- powerful stabilisation;
- excellent lenses;
- computational photography.
But camera technology does not change the fundamental nature of light.
The camera can only record the light that reaches it.
That is why a carefully lit subject filmed with relatively modest equipment can look excellent, while an expensive cinema camera pointed at a badly lit scene can produce surprisingly ordinary results.
Lighting Is Part Science and Part Art
There is plenty of physics involved.
We can study:
- reflection;
- refraction;
- scattering;
- inverse square behaviour;
- colour temperature;
- spectral output;
- polarisation.
But there is also artistic judgement.
How much shadow feels right?
Should the scene look warm or cold?
Should the background disappear or attract attention?
Should a face look natural, dramatic, mysterious or inviting?
There is rarely a single "correct" answer.
That is what makes lighting so interesting.
My Approach: Build the Picture Before Pressing Record
One of the temptations with digital photography and video is simply to start recording because recording costs almost nothing.
I think it is often worth resisting that temptation.
Spend another few minutes looking at the frame.
Move the light.
Move the subject.
Move the camera.
Remove something distracting from the background.
Add a little reflected light.
Turn one unnecessary lamp off.
Then look again.
A few minutes spent preparing the light can save considerably more time trying to rescue the picture during editing.
And there are some things that editing simply cannot completely repair.
Conclusion: Learn to See Light
Buying better equipment can certainly improve photography and filmmaking.
I enjoy good cameras and lenses as much as anyone.
But one of the most valuable upgrades costs nothing:
learning to notice light.
Look at how light falls across a face.
Look at how it reveals the texture of wood or metal.
Watch what happens to the garden as the Sun moves lower in the sky.
Notice reflections in glass.
Look at the difference between direct sunlight and an overcast afternoon.
Move a lamp six inches and watch a photograph change.
Once you begin thinking this way, lighting stops being something you simply switch on.
It becomes another creative tool.
And whether you are photographing wildlife, recording a science experiment, making a YouTube video, filming an interview or creating a dramatic short film, the same principle keeps returning:
Get the lighting right, and much of everything else becomes easier.
The camera matters.
The lens matters.
The sound certainly matters for video.
But before pressing the shutter button or pressing record, there is one question worth asking:
What is the light doing?
