Line #2

This photo satisfies requirement 1. I took this photo because I wanted to contrast the curvy corner of the table and the hard edges and corners of the piano keyboard. I tried to use relatively little light possible to give it a somewhat gloomy and mysterious atmosphere.

 

I used a low aperture to get little light, lowering my iso as well as increasing my shutter speed. This allowed me to let in as little light as possible, which lead to the mysterious surroundings of the keyboard piano.
