Experiments with exposure.
1. Row of Capital Bikeshare bikes on the street at night — A very dark photo. I chose a higher ISO, even though higher ISOs introduce more noise, to increase light sensitivity. A very low shutter speed created the motion effect of the cars, and also allowed for more light.
2. Balcony at sunrise. — A brighter color in dark surroundings. I particularly liked the contrast with the silhouettes of the chair and doorframe. I chose an extremely low shutter speed of 30, set the camera on a table, and used a two-second delay so the camera had time to steady after I pushed the button.
3. Subway train pulling into the station. — A dim environment lit up by the harsh lights of the train and highlighted by the muted red track lights. A lower shutter speed helped capture the sensation of the train hurtling forward.
4. Wall light from below. — Small depth of field in a very bright environment. I used the highest shutter speed on my camera and the lowest ISO and f-stop settings.
