The bowl is cherry. The apple is soft maple with a walnut stalk, which I also turned. The best way to learn to make either is to take a class and then search for turning videos on youtube. The cuts for making a bowl are quite hard to understand without being shown hands-on.
Both pieces were polished up to 600 grit and then finished with butchers block finish (some mix of mineral oil, beeswax and carnauba wax).
To photograph them, I used available light from a window, black IKEA table and a Nikon D3100 set on manual mode with 35mm lens. The black background and light wood meant that normal metering didn't work well.
