Painting light sources can be a tricky but fun endeavour. The two most common types of lighting are hard lighting and ambient lighting. Hard lighting is direct and intense, with distinct shadows, while ambient lighting refers to natural light sources like the sun, resulting in softer shadows. When painting a light source in front of a subject, it's crucial to understand the basics of how light behaves and its interaction with shadows. This involves considering the position of the light source, the angles, and the resulting brightness and darkness of different areas. Techniques such as light painting can be employed, where a light source is introduced in front of the camera to illuminate the subject and create eye-catching effects. Additionally, understanding the rules of object-source lighting (OSL) is essential, ensuring that lit areas appear brighter than unlit surrounding areas and maintaining consistency with the light source's colour and intensity.

Hard lighting vs. ambient lighting
Painting a light source in front of the subject is a complex task that requires an understanding of lighting types and their effects. The two most common types of lighting are hard lighting and ambient lighting.
Hard lighting involves a direct and intense light source that creates strong and distinct shadows with prominent lights and darks. To control hard lighting, one must manage the lighting ratio, or the relative levels of brightness, between the lights and shadows. Hard lighting can produce edgy effects and interesting shadows when used creatively, such as by placing the light source away from the camera.
On the other hand, ambient lighting refers to natural light sources like the sun, as well as artificial sources like floor lights and windows. It produces softer lights and shadows with less contrast, helping to set the tone and mood of a space. When painting with ambient lighting, it is recommended to prepare a grayscale with a maximum of six shades to guide the lighting process.
Before painting, it is essential to experiment with different light source placements to achieve various lighting effects. This can be facilitated by using tools that allow for easy adjustments of the light source position, such as 3D drawing figures. Additionally, understanding the principles of old master paintings, where the light source is typically placed in front of, above, and to the right of the subject, can be beneficial.
When painting with hard lighting, it is crucial to pay attention to the depth of shadows to avoid an unnatural appearance. Balancing hard lighting with ambient light in the environment can help create more successful images. Ambient lighting, with its softer and more subtle effects, often serves as a base for other lighting techniques.
In conclusion, both hard and ambient lighting have distinct characteristics and applications in painting. Hard lighting creates intense and distinct shadows, while ambient lighting produces softer and more natural illumination. By understanding and combining these lighting types, artists can effectively depict light sources in front of their subjects, creating believable and visually appealing compositions.

Using light to create shadows
Painting light and shadow is a complex subject, with artists dedicated exclusively to lighting. There are two common types of lighting: hard lighting and ambient lighting. Hard lighting is direct and intense, with light coming from a specific point, resulting in strong and distinct shadows. Ambient lighting, on the other hand, refers to natural light sources like the sun, creating softer shadows with less contrast.
When painting with a light source in front of the subject, understanding the behaviour of light and shadow is crucial. Here are some instructive guidelines for using light to create shadows:
- Positioning the Light Source: The placement of the light source relative to the subject determines the direction and intensity of shadows. A common suggestion is to position the light source in front, above, and to the right of the subject, which can create interesting lighting effects.
- Understanding Core Shadows: Start by identifying the core shadows and highlights to establish the direction of the light. Core shadows are the areas that receive the least amount of light, and they help define the form and depth of the subject.
- Creating a Grayscale Palette: Prepare a grayscale palette with different shades, ranging from light to dark. This will help you gradually build up the lighting effects, adding depth and dimension to your painting.
- Lighting Techniques: Hard lighting produces crisp and clearly visible shadows, while ambient lighting results in softer, less distinct shadows. You can experiment with different lighting techniques to achieve the desired effect, keeping in mind that hard lighting is generally easier to work with initially.
- Observing Shadow Shapes: Pay attention to the shapes of the shadows cast by objects. The shape of a shadow is influenced by the object casting it and the surface onto which it falls. Observing these shapes accurately will help you ground your subject and create convincing shadows.
- Edge Quality of Shadows: Notice the edge quality of the shadows. Direct sunlight will produce hard edges, while a cloudy sky or diffused light source will result in softer, blurry edges.
- Colour Temperature: Understand the colour temperature of your light source and its impact on shadows. Generally, warm light creates cool shadows, and cool light creates warm shadows. This is because of the complementary colours involved in creating shadow colours. For example, to create a neutral shadow in warm light, you would mix blue (a cool colour) with orange (a warm colour).
- Reflected Light: Consider the impact of reflected light on shadows. Surfaces like walls or tables can reflect light into the shadows, affecting their colour and temperature. This is especially noticeable with white objects, which reflect more light into their shadows.
- Experiment with Different Light Sources: Don't be afraid to experiment with different light sources and positions. Practice placing the light source in various locations to achieve different lighting effects and shadow patterns. This will help you understand how light and shadow interact.
- Understanding OSL (Object Source Lighting): In miniature painting, OSL involves creating the illusion of a light source that may not be present in the scene. To achieve this convincingly, follow the physical laws that govern how light behaves, such as the Cardinal Rule of OSL: lit areas always appear brighter than surrounding unlit areas.
Remember, lighting and shadows are essential elements in creating convincing and realistic paintings. By understanding and manipulating light sources, you can master the art of using light to create captivating shadows that bring your paintings to life.

Painting with light in photography
Light painting is a photographic technique that involves capturing moving light sources or moving the camera during long exposures. This technique, also known as light art, LAPP, or light graffiti, has been used for both artistic and commercial purposes since the 1880s.
To create light paintings, photographers use various light sources, such as flashlights, sparklers, phone lights, or even lightsabers, to illuminate the subject or space. The camera's shutter speed is extended to allow for long exposures, capturing the movement of light over time. One can also move the camera itself during the exposure to create light trails and unique effects.
When using light painting techniques, it is essential to dress in dark clothing to avoid being visible in the photograph. Additionally, photographers should be prepared to experiment and play with different light sources and camera settings to find their unique style. Practicing autofocus techniques and adjusting exposure settings are also crucial steps in achieving the desired results.
Notable photographers who have experimented with light painting include Man Ray, Barbara Morgan, Peter Keetman, Eric Staller, Dean Chamberlain, Jacques Pugin, Steve Mann, Vicki DaSilva, and Tokihiro Satō. These artists have contributed significantly to the development of light painting as an art form, incorporating choreography, performance, and innovative technologies into their practices.

Creating the illusion of a light source
There are two common types of lighting: hard lighting and ambient lighting. Hard lighting is direct and intense, with distinct shadows, while ambient lighting is softer and comes from natural light sources like the sun. When painting a light source in front of a subject, you will likely be using hard lighting, as it is more obvious and easier to understand.
To create the illusion of a light source, you must follow the rules that govern how light behaves. For example, the cardinal rule of Object Source Lighting (OSL) states that lit areas always appear brighter than the surrounding unlit areas. This is important to remember when painting coloured light sources, as the light source should be lighter than the areas it illuminates. Another rule to keep in mind is that lit areas appear no brighter than the light source they are lit by, which can be challenging when painting saturated colours like red or purple.
When painting a light source in front of a subject, it is essential to consider the light angle and the position of the light source. You can experiment with different positions and lighting effects to achieve various effects. It is also crucial to be aware of cast shadows and ensure they logically fit with the subject and lighting. The longer the cast shadow, the softer its edge becomes, and it behaves predictably on a flat surface. However, when there are different levels or surfaces in the shadow's path, the shape can be altered.
Additionally, when working with a single light source, be mindful of reflected light. For example, if you're painting a face, the cheek on the dark shadow side may have reflected light. By understanding these principles and experimenting with different techniques, you can create a convincing illusion of a light source in front of your subject.

Lighting effects and OSL
Painting light sources and their effects is a complex topic, and there are artists who dedicate themselves exclusively to lighting. The two main types of lighting are hard lighting and ambient lighting. Hard lighting is direct and intense, with distinct shadows, while ambient lighting refers to natural light sources like the sun, which cast softer shadows.
Object-source lighting (OSL) is a technique used in miniature painting to create a dramatic lighting effect. OSL involves depicting an object as the light source, such as a torch, lamp, or glowing sword. The light source can also be part of the environment, like molten lava or toxic sludge. The key to achieving believable OSL effects is to follow the physical laws that govern how light behaves. One of the fundamental rules of OSL is that lit areas always appear brighter than the surrounding unlit areas. This rule is often violated when portraying coloured light sources, especially with darker colours like green, red, or purple. To avoid this, it's important to highlight the areas where the light will fall before applying any glazing or colouring.
When planning your OSL project, it's crucial to understand your light source and how it will impact the objects around it. Reference photos can be extremely helpful, especially those with low lighting conditions. Once you know the direction of the light, you can start blending your light colour with the other colours on your model. An airbrush is a useful tool for achieving smooth fades and gradients, but you can also use other techniques like dry brushing or speed painting.
To create the illusion of a light source that is not actually present in the scene, artists can use lighting effects. This technique is more general and suggests a light source that is "off-camera" or not directly depicted in the composition. By understanding the rules of light behaviour and how it interacts with objects, artists can create convincing lighting effects that enhance the overall impact of their artwork.
