The Photo 101 weekend edition asked us to play with light. I read the Fundamentals of Light and bought a couple of the suggested apps for iPhones. SlowShutter gives your iPhone camera some level of digital single-lens reflex camera functionality, including manual settings for aperture, shutter speed and light sensitivity. The photographic term “exposure” is the “amount of light captured in a photograph” and you can control it through aperture (the size of the hole of the lens), shutter speed (how long the lens stays open) and light sensitivity. SlowShutter gives you three “capture” modes – motion blur, light trail and low light.
I experimented last night taking a picture in a completely dark room except for a slit in the blinds that showed one lone street lamp. I used the low light capture mode and experimented with “low,” “medium” and “high” exposure boosts and 4 to 8 second shutter speeds. I could not believe any light was captured at all.
Today, I had an appointment in Dupont Circle and I played with the motion blur and light trail modes.
