This video course provides over 1.5 hours of instruction on mastering HDR image-based lighting workflows within Blender's Cycles render engine. The curriculum spans five chapters, covering essential concepts like 32-bit textures, high dynamic range, and tone mapping techniques. Lessons focus on practical scene setup, including how to control light direction, avoid blown-out backgrounds, and combine multiple HDRIs for complex lighting results. The tutorial package includes all necessary project `.blend` files, a bonus tutorial segment on evaluating light properties, and four 2k HDR environments.
