A face can look flat and boring in the same room, and then suddenly look three-dimensional and exciting with different lighting. The difference almost always lies in the light. In this workshop you will learn not simply to accept light, but to control it deliberately. You will find out how shadows shape your images, what role light modifiers play, and how to use the on-camera flash as a creative tool instead of only using it for fill light. The examples mostly come from portrait photography, but can also be applied to landscapes.

Key Takeaways
- You control light through four adjustable factors: direction, distance, hardness, and color.
- The direction of the light is crucial. Light from above, slightly from the side, usually looks the most natural. Light from below looks unnatural.
- Shadows are often more important than the lit areas, because they determine structure and depth.
- The larger the light source is in relation to the subject, the softer the light becomes. Light modifiers help with this.
- With natural light, reflectors, your position relative to the sun, and the time of day are the most important tools.
- With an on-camera flash, it is best to work in manual mode. That way you keep control over power and exposure.
Step-by-Step Guide
Step 1: Understanding the Four Adjustable Factors of Light
Before you set a light, you should know what you can change. You essentially have four options: the direction of the light, the distance to the subject, the hardness of the light, and the color of the light. If you don't like an image, ask yourself which of these factors you need to change to achieve your goal. Sometimes a single change is enough, sometimes several have to work together. Get into the habit of asking exactly this question after every photo.
Step 2: Choosing the Direction of Light Deliberately
Light coming from below looks like something out of a horror scene. Light falling very steeply from above creates dark eye sockets and unattractive shadows under the nose and chin. A good starting point is a classic position: about 30 degrees to the side and 30 degrees above the subject. This creates a face with depth, without one side disappearing completely into darkness. The light must not be placed too far to the side, otherwise one half of the face becomes almost black. In each case, consider whether you want to balance both halves of the face or deliberately allow a dark shadow.
Step 3: Using Catchlights as Clues
The reflections in the eyes reveal a lot about the light used. A small bright dot indicates a light source whose position you can read. A round reflection points to a round light source, such as a beauty dish. This helps you analyze other people's images and recreate lighting setups. So take a close look at portraits in magazines or on platforms if you want to learn how other photographers work.
Step 4: Using the Distance to the Subject Deliberately
Light intensity decreases with distance. A light source close to the subject illuminates it strongly, while the background is lit much more weakly. This light falloff can be used excellently to separate the foreground from the background. A classic example is the portrait by the window: the person stands close to the window, while the background in the room quickly becomes dark. However, make sure that no additional light comes in from behind, otherwise the separation loses its effect.
Step 5: Distinguishing Between Hard and Soft Light
The hardness of the light depends on the size of the light source and its distance from the subject. A small source, or one close to the subject, produces hard, sharply defined shadow edges. A large or distant source delivers soft light with gentle transitions. The sun is very large, but extremely far away, which is why sunlight is nevertheless hard. Soft light is very forgiving and is suitable for getting started. Hard light is more demanding, but in return brings an enormous amount of structure and contrast to the image. So begin with soft light and slowly work your way up to hard light.
Step 6: Using Light Modifiers Correctly
A bare flash or a bare light source is small and produces hard shadows. Light modifiers make the light softer and more targeted. A softbox enlarges the apparent light source and diffuses the light. A beauty dish delivers a medium-hard light quality with a nice falloff toward the edges, which gives the image a vignette. When choosing, pay attention to the shape: round light modifiers produce round catchlights and usually look more natural than angular ones. A honeycomb grid in front of the light modifier additionally focuses the light and creates higher-contrast, directional effects. Never touch the flash tube of a studio flash, as this damages the lamp more quickly.
Step 7: Use Natural Light to Your Advantage
With sunlight, the main rule is: don't immediately put your subject in full sun. It is better to have the sun behind you or to hide it behind trees, people, or other objects. This way the sun remains visible as a fine rim of hair light without overexposing the entire image. The best conditions are offered by the hours shortly before sunset until shortly before the blue hour. Apps like Golden Hour or Fotopilz show you exactly when these time windows occur. A reflector is an inexpensive helper for bouncing light back from the side and brightening shadows on the face. The different surfaces deliver different results: white looks neutral, silver reflects more strongly, gold creates a warm tone, and black serves as a flag to block light. A translucent side diffuses sunlight when you are standing directly in the sun.
Step 8: Control the Color of the Light
The color of the light strongly influences your images. Common flashes and video lights are set to neutral light, which reproduces colors naturally. Ceiling lights or street lamps, on the other hand, often deviate significantly and look unattractive. The time of day also changes the color: the golden hour is warm, the blue hour is cool. If you are shooting in mixed light, orient yourself to the light that illuminates your main subject and set the white balance accordingly. A gray card helps with this, but is cumbersome. In RAW format, the white balance can be corrected well afterward.
Step 9: Set the Speedlight Manually
The speedlight is a flexible tool, especially when you detach it from the camera hot shoe. The TTL automatic mode works in many situations, but is not always reliable. That is why manual mode is worthwhile. Start by taking a photo without flash, and set shutter speed, aperture, and ISO so that the ambient light is right. Then you activate the flash and first reduce its power until the subject is correctly exposed. The power is specified in fractions, where a larger number in the denominator means less power. As long as you keep the distance to the subject constant, the exposure remains stable. Also note the flash sync speed of your camera. If the shutter speed is chosen too short, the flash can only illuminate part of the image.
Step 10: Bounce, Diffuse, and Trigger the Flash
A flash pointed directly at the subject quickly looks flat. Therefore, turn the flash head toward a wall or ceiling. The light becomes significantly softer as a result, because the reflecting surface becomes the new light source. Make sure that there is actually a surface behind you that reflects the light back. A diffuser, such as a small cover over the flash head, diffuses the light further. With a radio trigger, you can position the flash independently of the camera, for example to the side or slightly elevated. If your flash has a photocell, you can trigger additional flashes by light pulse. For live situations, however, plan time for troubleshooting, because technology doesn't always work on the first try.
Step 11: Build a Studio Lighting Setup
In the studio you have more power and variability, but preparation is more important. First set the effect lights, for example rim lights that create a fine edge of light along the contours. Set the camera so that the background stays dark, and adjust the effect lights until you see their effect. Then switch on the main light and increase it until the subject is correctly lit. This order prevents your main light from overpowering the effects. A ring light produces even light without shadows, but quickly looks boring. A setup of a round main light and two rim lights, on the other hand, is a rewarding starting point for high-contrast, three-dimensional portraits.
Summary ??? Lighting and Flash: Controlling Shadows Deliberately for Portraits
Light is not a coincidence, but a design tool that you control with direction, distance, hardness, and color. Start with soft light and a classic position to the side and slightly above the subject. Use natural light deliberately with backlighting, reflectors, and the right time window. When using an on-camera flash, work manually, bounce the light, and use light modifiers to shape it. Once you master these basics, every photo will have more depth and expression.
FAQ
How can I tell whether an image was created with artificial light?The catchlights in the eyes show the shape and position of the light source, and the direction of the shadows also reveals a lot.
Why should I avoid my camera's built-in flash?The built-in flash points straight ahead and often fires unintentionally at landscapes or subjects, which creates flat, unflattering light.
What size should a softbox for an on-camera flash be?Smaller softboxes are usually more sensible, since large shapes swallow a lot of light. A size of around 40 cm is enough for portraits if you work close to the subject.
How do I prevent sun flares?Avoid letting the sun shine directly into the lens. A lens hood also helps, and higher-quality lenses show fewer flares.
Do I absolutely need a gray card when working with mixed light?No. In RAW format, you can correct the white balance afterward. Above all, make sure that the light illuminating your subject has a neutral color.
