Assignment One: pulling focus
Turn your camera to video mode.
Hit the record button to begin filming and to end filming after each clip.
Looking at the LCD screen in Live View, move your focal ring and practice 'pulling' focus. Notice what happens when you move the ring to the right vs. left (this can vary from lens to lens).
Abundant light: Begin in a well-lit space, with still objects.
Start at f/8 and practice slowly pulling focus until the object is crisp on your screen.
Next, try purposely pushing your focal plane beyond your object, and also pull it so the focal plane lands in front of your object just to observe the range of the focal plane.
Then move to f/4 and repeat steps to pull focus again.
Finally, open your aperture up wide and repeat the steps. (You'll also need to adjust ISO most likely by this point)
Move yourself and/or the objects to practice both closer and further away from you. Note how the focal range feels different based on your distance from the object.
Lower light: Repeat the same exercise with the still objects in a darker area, or simply close the blinds/curtains.
Once you are comfortable with this, repeat the process in a well lit area with moving subjects. Perhaps kids playing or a pet moving around. Then try it in a darker space.
This exercise will give you a sense of the latitude you have with each focal plane, in various lighting and shooting conditions.
