Three Point Lighting - Blender 2.8 fundamental ภาษาไทย

Introduction

This tutorial will guide you through the process of setting up a Three Point Lighting system in Blender 2.8. This lighting technique is essential for creating visually appealing and professional-looking renders, especially for portraits and product displays. By the end of this tutorial, you will understand how to effectively position and utilize three types of lights to enhance your 3D objects.

Step 1: Understanding the Three Types of Lights

The Three Point Lighting setup consists of three distinct lights, each serving a unique purpose:

• Key Light: This is the primary light source that illuminates the subject. It's usually the strongest and most directional light in the setup.
• Fill Light: This light softens and fills shadows created by the key light. It is typically less intense and positioned opposite the key light.
• Rim Light (or Back Light): This light is placed behind the subject and creates a highlight around the edges, helping to separate the subject from the background.

Step 2: Setting Up the Key Light

1. Add a Light Source:

   • Open Blender and switch to the "Layout" workspace.
   • Press Shift + A to open the Add menu and select Light -> Point Light (or another type of light that suits your needs).

2. Position the Key Light:

   • Move the key light in front of your object, at a 45-degree angle above it.
   • Adjust the intensity of the light using the properties panel. Start with a strength of around 1000 watts.

3. Adjust the Color:

   • Change the light color to fit the mood you want to create. Warmer colors (yellows and oranges) are often used for a soft look, while cooler colors (blues) can create a more dramatic effect.

Step 3: Adding the Fill Light

1. Insert a Fill Light:

   • Again, press Shift + A and add another Point Light.

2. Position the Fill Light:

   • Place this light opposite the key light, at a lower intensity (about 300-500 watts).
   • Position it at a 45-degree angle to the side and slightly below the object to soften the shadows.

3. Modify the Light Settings:

   • You can also adjust the color of the fill light to match or complement the key light.

Step 4: Incorporating the Rim Light

1. Create a Rim Light:

   • Add another light source by pressing Shift + A and choosing Spot Light or Point Light.

2. Position the Rim Light:

   • Place the rim light behind the object, angled towards the back of the subject to create a rim effect.

3. Set Intensity and Color:

   • Set the strength to around 500 watts and choose a color that contrasts with the key light to help the subject stand out.

Step 5: Fine-Tuning the Setup

1. Adjust the Lights:

   • Go through each light and tweak their positions and intensities as needed to achieve the desired look.
   • Use the viewport shading options to preview how the lighting affects your render.

2. Check Shadows:

   • Ensure that shadows are soft and natural. You may need to adjust the strength of the fill light or reposition it for better results.

3. Render Preview:

   • Use the render preview mode to see how the final output looks and make any last-minute adjustments.

Conclusion

By following these steps, you can create a professional Three Point Lighting setup in Blender 2.8. This technique is crucial for showcasing 3D models effectively, whether for portraits or product displays. Don’t hesitate to experiment with light positions and settings to find the best combination for your specific project. Happy rendering!
