 MOTION
CONTROL
 
Henri Cartier Bresson-"Decisive
Moment" __Paul Pearce "Go Fish"
We first learned
how to control our exposures with the "Black White and Gray" execise.
Keep this in mind when making motion photographs. Adjust your evposure value to
get a properly exposed image. Make
sure you understand how to adjust the shutter speed by changing the aperture (aperture
priority mode). This is how we did the exercise in class.
The goal of this
assignment is to understand and master the use of shutter speed to control how
movement looks within the photograph. You will need a tripod to do
this assignment. You can use se the Equivalent Exposure wheel
to help check your changes in shutter speed and aperture. 
Phase
One ~ Make a series of photos of moving subjects (bracket
your speeds) 1) Find a subject that is moving in moderate light. Direct
sunlight is too bright to allow slow shutter speeds. If the light is too dim,
you wont be able to freeze the motion with a fast shutter speed. Cloudy
or shady outdoor light and bright indoor light should work best. The light in
our classroom is just about right. Your subject should be predictable and consistent.
When starting out you should simplify what you shoot. Pick something that wont
stop or move away as you set up to shoot. The lighting should also be consistent.
2)
Set up your tripod and compose your photograph, framing to concentrate on the
motion and eliminate distracting elements. You will make multiple exposures
at different shutter speeds without moving the camera. 3)
Set your camera to "aperture priority" or change the aperture first
and then check the exposure. If you subject is lighter or darker than "medium
gray" make exposure value adjustments to get the correct exposure.
4) Adjust
your lens opening (f/stop) to the smallest opening (highest number) like f/16.
This will require a long shutter speed to give you the proper exposure. Make
your first exposure. 5)
Change your lens opening to the largest opening (lowest number) like f/2 or f2.8
and change your shutter speed to get the proper exposure. Your shutter speed should
be much faster. Make your second exposure. If the lighting is not optimal,
you might not be able to use the largest and smallest lens openings- changing
the light will help (lighter of darker). 7)
Shoot another exposures that falls between exposures # 1 and # 2. Now
repeat this sequence with 2 more subjects, try for variety. Try to go beyond shootinganything
that moves- (no ceiling fans). You should be creative and selective in your framing
to make an interesting composition. Make
sure that you have some contrast in between your moving subject and the background.
A slow shutter can make your subject transparent and it could disappear.

Phase
Two~ Experiment with different motion control techniques. Remember
the techniques we discussed in class- Panning the camera, extra long exposures
and fast shutter speed to freeze motion.
Shoot a variety
of images to try out the different effects. You can shoot long exposures
in low light and fast exposures in bright light without making a pair
of images. You will submit a strong example of Motion in your
Final Portfolio at the end of the
semester.
Use a tripod, dont move the camera, don't change focus between
images, just aperture and shutter speed.
You have to have the right lighting to accomplish this.
DO
NOT CHANGE THE FOCUS ON YOUR LENS BETWEEN THESE SHOTS!
Do not try this part of the assignment in direct sunlight. With your
tripod it can be done in fairly low light. Slow motion is impossible
to get in bright sunlight with 400 speed film.
Be
sure to check your light meter to avoid over and under exposure.
Two
Prints (5X7):
Make two photographs of the same subject. One will show frozen motion
and the other blurry.
These two exposures should be taken from exactly the same position -
they should look the same except for the change in motion.
You will turn in your film log and contact sheets that show how much
effort you put into this assignment.
Make sure everything that you turn in is labeled. Name - Date - Roll
