Day 1 I took Mike Jennings class. I learned so much (too much)
Here's the class description:
Dynamic Digital Collage
You will learn to use Adobe Photoshop to create digital collages with sophisticated layering. Find out how to quickly isolate elements from their backgrounds. You will learn to make layers interact with one another using blending modes and painting with transparency. Add depth and dimension difficult to achieve in the physical domain using layer styles and transformations. Master the Photoshop Text tool. Filter your elements for fabulous effects.
Here's an example of what I did -- the images were Mike's, but I manipulated and layered them!
