Light is light, is light...
Taken with a Nikon D50 and AF Zoom-Nikkor 70-300mm f/4-5.6G lens
My opinion:
Light is light, is light... its diffused, its direct, its reflected, its coloured... yes. But its also different in each context because it changes the mood of a photograph. A park at noon is quite likely to be much more drab than a park in the morning. Both in direct sunlight, but the morning's sun a bit more yellow/golden, and streaming through the branches at an angle...
Light is all around you, but actually looking for interesting light will help you understand it better. I'd also add that looking at just the light is not enough, look at the textures, effects, patterns and paths that it creates, look for colour casts, reflections, flare, and sparkles as it reflects off various surfaces...
If you're a photographer who wants to work in a studio at some point of time, looking for, and remembering lighting moods and feels is invaluable when you're trying to recreate emotions in a studio environment.
