Another good example of how something can be exposed well (wood) with some very washed out elements (the slides). Understanding this can help create interesting images by combining the exposure in relation to your overall composition.
What works better. Dark foreground and well lit background or the other way around. Good to play with the exposure levels here.
Another difficult exposure situation. I really like the variety of color on the walls of the slide. I might try to crop out the dark area around the tunnel. You can also do this in Photoshop after the fact.
