- Be aware of the characteristics of light. Learn to think about how that scene you're observing now would look at a different time of day (or night). The differences can be dramatic.
- There is no "good" or "bad" light. Yes, the golden hour is great for beautiful images. Sometimes, you want to communicate something other than just "beautiful." Sometimes the harsh light of mid-day is exactly right for communicating your story.
- Obsess about observing light. Even when you don't have a camera. Look at contrast, how the shadows are illuminated. I find it useful to think about how many stops difference I think there are between the shadows and highlights, and about how I would expose an image, if I were taking it.
- Give it a try, experiment. To me, this point follows on the one above. Why ever be without a camera? If you see it, shoot it. It's digital, right? You can simply delete it later, with no cost, and with the potential of learning something.
- Don't forget that you can post-process. Learn to shoot challenging scenes with a plan in mind for post-processing. Want to capture that person's face, but also want the sky correctly exposed? See if you can capture the sky and bring the face exposure up a little in post-processing.
