Book Review: Blender Cycles: Lighting and Rendering Cookbook by Bernardo Iraci

Reading this book I came to realize how Blender can produce images with photorealism accuracy.  Bernardo Iraci's recipes are float point precision from RGB colors, Index of Refraction to factoring levels in mixing nodes.  Photographic terms: depth of field, bokeh effect and exposure levels are used.  The author begins by discussing GPU vs. CPU and video cards.  He introduces the reader to the three point light system using emitting planes and gives those lighted mesh subtle hues.  I like the way he lights the environment.  An hdr image is loaded in the environment texture which adds reflection. He uses sun position along with an IBL plug in and chooses Latitude, Longitude and Time settings for the outdoor landscape.  Grass is made with the particle system which is ready for animation.  He guides the reader for changing the scenes.  The interior scene with plant, lamp, chair bathed in sunlight becomes night.  IES, a plug in used by professionals, saves on polygon count.  Throughout the book the author maintains focus on the lighting,  IOR, rendering time, nodes while he develops textures for a glass full of water,  a glass of wine, bottle of wine, grapes,  a car with realistic reflections, toys inside a space ship, and a model of a young lady by the sea.


  1. I would love to learn how to use Blender, but I am not good with animation software.

    1. There is much to learn, but Blender software is free and there are many video tutorials on the blender website and youtube. You can do it Aya! Thank you for taking the time to read my book review.
