I recently ran a public webinar, Layers and Masks. I covered the whole range of layers available within Photoshop including Smart Object layers and 3D layers.
There is a video available of the whole session from MacBites Learning.
Full details of what was covered are available in this free preview file.
The webinar lasted 1 hour and 13 minutes (plus 17 minutes of Q&As) and covered the following topics:
- Layer Basics
- Layer Types
- Filtering Layers
- Text Layers
- Shape Layers
- Adjustment Layers
- 3D Layers
- Layer Management
