Object Source Lighting (OSL) is a technique used in miniature painting to create the illusion of light emanating from a specific object or area. By incorporating OSL into your painting, you can add depth and drama to your miniatures, making them stand out on the tabletop.

In this article, we will explore different techniques for incorporating OSL into your miniature painting projects. We will cover the basic principles of OSL, the materials needed, and step-by-step instructions for creating dramatic lighting effects.

The Basic Principles of OSL

OSL is based on the basic principles of light and shadow. When painting a miniature with OSL, you must first identify the object or area that will be the source of the light. This could be a torch, a magical spell, or even a glowing gemstone.

Next, you need to determine the direction of the light. Where is the light coming from? Is it illuminating the entire miniature, or is it focused on a specific area?

Finally, you need to consider the color of the light. Different light sources emit different colors of light, such as warm yellows, cool blues, or eerie greens.

By considering these factors, you can create a realistic and convincing light effect on your miniature.

Materials Needed for OSL

To create an OSL effect on your miniature, you will need a few essential materials:

  • A miniature to paint
  • Paints in the colors of your choice
  • Brushes in various sizes
  • A palette for mixing paints
  • A light source, such as a lamp or flashlight

Step-by-Step Instructions for Creating OSL

Now that you understand the basic principles of OSL and have gathered the materials you need, let's dive into the step-by-step instructions for creating an OSL effect on your miniature.

Step 1: Prime and Basecoat the Miniature

Start by priming your miniature with a black or dark-colored primer. Next, basecoat the miniature with the colors you want to use for the non-lit areas. This could be armor, clothing, or skin tones.

Step 2: Identify the Light Source

Identify the object or area that will be the source of the light. This could be a torch, a spell effect, or a glowing gemstone. Paint this area white or a very light color, as this will be the brightest part of the miniature.

Step 3: Paint the Shadows

Next, paint the shadows on the miniature. This involves using darker colors in the areas that are furthest from the light source. For example, if the light source is a torch in the character's hand, the area behind the character's body would be darker.

Step 4: Paint the Light

Now it's time to paint the light itself. Use a glaze or transparent paint in the color of your choice to create a gradient of color from the light source to the surrounding areas. Build up the intensity of the color gradually, making the area closest to the light source the brightest.

Step 5: Fine-Tune the Effect

Once you have painted the light, you can fine-tune the effect by adding highlights and reflections. Use a very light color to add highlights to the brightest areas of the light source. You can also add reflections of the light onto nearby surfaces, such as the character's armor or clothing.

Step 6: Final Touches

Finally, add any final touches to the miniature, such as details on the light source itself or highlighting other areas of the model. Stand back and admire your work!

Tips and Tricks for Creating OSL

  • Experiment with different colors and light sources to create unique and interesting effects.
  • Practice on a separate object or model before attempting OSL on your main miniature.
  • Use thin layers of paint to build up the effect gradually, rather than trying to achieve it in one coat.
  • Keep in mind the color temperature of the light source. Warm light sources, such as torches, will cast warmer colors on the surrounding areas, while cool light sources, such as magical spells, will cast cooler colors.
  • Remember to consider the direction of the light source when painting shadows and highlights.

Incorporating Object Source Lighting (OSL) into your miniature painting projects can add depth, drama, and visual interest to your work. By following the basic principles of light and shadow, gathering the necessary materials, and following these step-by-step instructions, you can create stunning lighting effects that will make your miniatures stand out on the tabletop.
