Using light and dark to create contrast

Painting light shining on a painting involves understanding how light interacts with objects and how to apply lighting effectively. Here are some tips for using light and dark to create contrast in your paintings:

Firstly, it's essential to grasp the fundamental concept that light illuminates the surfaces of objects facing the light source, while areas turned away from the light remain in shadow. This understanding forms the basis of creating contrast in your paintings.

When painting with light and dark to create contrast, it's crucial to select your colours carefully. For dramatic effects, consider using the chiaroscuro technique, popularized by masters like Caravaggio. This method involves using a dark base colour, such as raw umber mixed with ultramarine blue and a touch of phthalo blue, to form the foundation of your shadows. To add a touch of warmth to your shadows, incorporate a small amount of alizarin crimson.

When applying paint to create shadows, start with the darkest tones in the areas of deepest shadow. Use a filbert brush and work in broad strokes that follow the contours of your subject. Gradually build up the intensity of the shadow by adding layers of paint, allowing each layer to dry before adding the next. This technique will help you achieve seamless transitions between light and dark areas, a characteristic feature of chiaroscuro.

To enhance the contrast further, add highlights to your painting. Highlights represent the areas where light hits the object the strongest. Use a fine brush and a light colour, such as titanium white mixed with a touch of your base colour, to apply highlights sparingly for maximum contrast. Softening the edges of your highlights by using a dry brush to gently feather the paint outward will create a natural transition between light and dark areas.

Additionally, don't be afraid to experiment with different lighting setups. While having a single harsh light source can help create clearly defined shadows, using multiple light sources from different directions can make your lighting more compelling. Play with the direction and intensity of your light sources to find interesting effects. Remember, you can always dial it back if it feels too much.

Lastly, pay close attention to the values around the light. Ensure you have a full range of values, especially darks, so that the light in your painting truly shines. Consider using pastels, as they allow you to scumble light on top of dark without waiting for the paint to dry, creating beautiful luminous effects.

Understanding how light interacts with objects

Light behaves predictably by travelling in a straight line. However, when painting an indoor scene with multiple light sources, such as windows and lamps, achieving a realistic three-dimensional effect becomes challenging. The easiest way to learn to paint form and shadow is to have a single harsh light source illuminating the objects. This creates clearly defined shadows, making it easier to translate into your painting.

To capture the effect of light in your painting, remember that light is not just white; it can be composed of various colours. For example, sunlight can contain hues of yellow, pink, orange, and blue. By incorporating these colours into your highlights, you can create more vibrant and realistic lighting effects.

When painting shadows, avoid using pure black. Instead, opt for dark greens, purples, or blues, or a mixed chromatic black, to add depth and realism to your painting. The complementary colour to the object will usually create the most realistic shadow.

To lighten or darken colours, you can use the colour wheel to identify chromatically close colours. For instance, adding a small amount of yellow, a brighter colour, can lighten orange without dulling it. Similarly, you can glaze acrylics with water or a specific medium to lighten the shade.

Before beginning to paint, it is essential to sketch the composition to understand the lighting angles and define the focus of the painting. This initial sketch serves as a guideline and can be adjusted slightly when starting the underpainting.

By understanding how light interacts with objects and employing these techniques, you can create vibrant and realistic lighting effects in your paintings.

Choosing the right colours for highlights and shadows

Firstly, understand that light itself is colourful. It is not just white but consists of various colours like yellow, pink, orange, and blue. Thus, incorporating these colours into your highlights can make them more vibrant and realistic.

When painting shadows, avoid using pure black. Instead, opt for a mixed chromatic black, which will provide more depth and realism to your painting. Consider using dark greens, purples, or blues—whichever complementary colour works best with the subject you are painting. For instance, if you're painting a scene with green trees, a shadow on the ground would be more realistic in a dark green shade rather than pure black.

To lighten or darken a colour, you can add small quantities of white or black paint, respectively. However, be cautious when lightening a colour; only use a chromatically adjacent colour. For example, if you want to lighten orange, add a small amount of yellow since they are neighbouring colours on the colour wheel. This technique will brighten the orange without dulling it or creating a stark contrast.

Additionally, consider the background colours when choosing your highlights and shadows. For instance, if the background is lighter on the right and darker on the left, your highlights will stand out more on the left side. You can also use the background colours to create transparency in certain objects, such as a glass jug, adding a sense of luminosity.

Lastly, remember that light and shadow are interconnected. To showcase light effectively, you need to incorporate shadows into your painting. Start by sketching the light and shadow patterns to define the lighting angles and composition. This will help you choose the right colours for your highlights and shadows, ensuring they complement each other and create a realistic sense of depth and luminosity in your artwork.

Painting with different media to achieve the same effects

Painting with different media requires different techniques to achieve the same effects. Here are some tips for painting with watercolour, oil paint, acrylic paint, and pastel to create the effect of light shining on a scene:

Watercolour

Watercolour artists often aim to capture the essence of a scene, and light is an essential element in achieving this. To paint warm glowing light in watercolour, the key is to focus on contrast. This can be achieved by combining warm and cool colours, paying attention to the values and reserving the detail for the light areas of the painting.

Start by painting the lightest values of the scene, using your warmest colours. Then, paint a large middle-value shape, and finish with the darks and details. By simplifying the shadow areas and keeping the focus on the light areas, you can guide the viewer's eye to where you want it.

Oil Paint

When using oil paints to capture light, it's important to remember that light is more about tones than colours. The relationship between the different tones in your painting will make the light effect credible. Start on a toned canvas that can serve as your mid-tone, so both light and dark brushstrokes will be visible.

Use thicker paint for the light areas and gradually build layers of lighter colours, finishing with thick impasto marks for the brightest highlights. This will create a strong focal point as the eye is naturally drawn to the lightest colour. Focus on painting the light falling onto planes, and remember that light only exists in contrast to dark, so include plenty of dark areas to make your light stand out.

Acrylic Paint

When lightening a colour with acrylic paint, you can add white to the colour, but this may dull the result and reduce its chromatic intensity. Another option is to use the glazing technique by adding water or a specific medium to create transparency and lighten the shade. However, be careful not to add too much water, as it can reduce opacity and intensity.

Pastel

One technique to paint light with pastels is the notan technique, which is based on a Japanese design principle. This involves converting the pattern of light and dark into simple shapes, helping to identify the pattern and feel of the light through value. Start by creating a monochromatic underpainting, then move on to your pastel paper, sketching the gesture of the objects in the scene, varying their thickness and height.

Use the side of the pastel to lightly mass in the movement of the shapes in the foreground, applying more pressure for the shapes in the foreground and less for the background. Then, take a very dark colour and lightly glaze it over the darkest shapes. Finally, use a large bristle brush dipped in a painting medium to push the pastel around, using your whole arm to make the strokes.

Using light to create focus

Light is a crucial element in painting as it adds life and a touch of reality to the artwork. It is essential to understand how light interacts with the subject of your painting to effectively depict it. Here are some tips for using light to create focus in your paintings:

Firstly, it is important to remember that light and dark play off each other. You can't have light without dark, so make sure to include a full range of values, especially darks, to ensure that the light stands out. This involves creating a sketch to map out the composition, lighting angles, and values. The sketch serves as a guideline, allowing you to make slight adjustments when you begin painting.

When painting, remember that light behaves predictably, always travelling in a straight line. If you're working with a single light source, it becomes easier to define shadows and create a realistic, three-dimensional image. In such cases, the shadows will have sharp or blurred edges, which can be translated into your painting.

To create a sense of luminosity, you can add tiny dashes of extreme light where needed. You can also mix colours to achieve the desired effect. For instance, adding a hint of Raw Sienna to the light can keep the glow warm. Additionally, you can use different media to achieve various lighting effects. Pastel, for instance, allows you to scumble light on top of dark without waiting for the paint to dry, and you can create multicoloured light by scumbling different colours.

Finally, when painting with light, you can do so from a distance, illuminating the subject without the light appearing in the shot. Alternatively, you can shine light directly in front of the camera, creating a more obvious and eye-catching effect.
