The Photoshop Training Channel tutorials are really, really good. They have all the necessary details and are explained very well. Jesús Ramirez gives general tips here and there also. He just doesn't say "to this, then do this". He explains why and this makes these tutorials so educational.
This is the introduction to the video tutorial, which outlines what the tutorial covers:
In today’s tutorial I’m going to show you how you can use Photoshop CC’s 3D features to create a realistic composite between a 3D model and a Photograph.
You’ll learn how to place the 3D model in the right perspective and how to apply materials to the various pieces of geometry. Then you’ll learn to use IBLs (Image Based Lights) to help illuminate the scene and create reflections.
We’ll finish off the tutorial by using adjustment layers to adjust the brightness and color of the 3D model, and to create lights to further enhance this image.
After watching this tutorial, you will be well equipped with the knowledge to import 3D models into Photoshop and composite them in into your own Photographs.
