Throughout the class I experimented with the Layer Modes mostly, to take a look at what worked best.
In the situation that I will use this image, I want to have a dark image (sun blocking). Although I really like the modes like screen and hardlight, the problem with them is they look too fantasy scenary like, not what I'm looking for. Modes like the Multiply and Darken work better.
This is the Bump I created from the image, using high pass. I really like the tone difference throughout the image.
