Goal: To practice using Depth of Field and Rack Focus, with variations.
Objective 1: Use a zoomed lens and low shutter speed to create a short depth of field. Focus on something in the middle distance so that you have something in the background (behind the subject) that is visible but out of focus. (5-8 seconds)
Objective 2: Use a zoomed lens and low shutter speed to create a short depth of field. Focus on something in the distance so that you have something in the foreground (in front of the subject) that is visible but out of focus. (5-10 seconds)
Objective 3: Set up as in #2, and shoot 5 seconds like that (again), but then adjust the focus so that the foreground fades into focus while the background object fades out of focus. Avoid shaking the camera. (10-15 seconds)
Objective 4: Set up as #1, and then shoot 5 seconds like that; then adjust the focus so that the subject in fades out of focus while the background comes into focus. Bonus: put an actor in the background who comes into focus as you switch from closer to farther focus (rather than just have trees or buildings in the background come into focus. (10-20 seconds)
Extra Credit: Make them all interesting: add a mini-story...add dialogue...add other elements (but do not change the requirements), etc.
TIPS: This takes practice! If you have trouble, try varying some factors (e.g., distance of the subjects from the camera, distance of the subjects from each other, amount you are zoomed, etc.)
