Assignments can keep you shooting...
Here are some we had to do:
1) Day in the life of your town/city (on one roll): dawn to dusk, rush hour, lunch time, garbage trucks, etc. Purpose: pacing, planning, endurance.
2) Cover a public demonstration: act like a reporter, get the 'decisive moments'. Purpose: sizing up an event, anticipation, engagement of bystanders, feeling comfortable snapping strangers.
3) Asking: Go someplace public, 24 frames, ask and get 24 people pictures, complete strangers. No covertness. Hint: tell them you are a photography student. Works best with obvious 'student' camera. May take you all day. Purpose: Grow balls, capture interesting people, engaging them, etc.
4) Seeing Things: Capture light and shadow in interesting ways or from different perspective. Window reflections, sunlight on streetcar tracks, nighttime cityscapes, mirror reflections, ripples, shooting straight up or down, or from ground level, shadows, etc. Purpose: learning to see what light does.
5) Motion and zoom: Freezing motion with fast shutter, blurring with slow shutter, panning with moving cars, people -- blurring background, zoom out on objects moving toward/away. Purpose: basic mechanics to adding drama.
6) Self-Documentary: Photo-document your hobbies and chores. Make a story-board. Purpose: telling a personal story.
We generally struggled, procrastinated, pushed and stretched, and then mostly surprised ourselves.
