ASSIGNMENT: APERTURE/SHUTTER SPEED ASSIGNMENT  
 

Photos by Andrew Churchhill

 
 OBJECTIVES:     
  To illustrate the effects of different apertures and shutter speeds.  
 PROCEDURES:     
 

You will need to do this with a camera that has manual shutter and aperture.

If the camera you are using has a zoom lens, zoom it to its widest setting (this will make its widest aperture available to you).

Set-up #1- Stationary Subject

Aperture Examples - The camera should be between 5 and 10 feet from your subject. The subject could be a person, pet, object, pretty much anything that doesn't fill the whole frame. Have the subject 40 feet or further from a background. The background needs to have some detail in it. It could be a house, trees, cars, etc. Compose the shot so you see the subject and the background. Set the camera to its widest aperture. This will be the smallest aperture number. The number will be different depending on the lens you have on the camera. Focus your lens on the subject and adjust the shutter spend until the camera meter indicates correct exposure. Take at least three shots using this exposure.

Before anything changes, set the shutter speed to 1/60 (about the slowest you can safely hand hold without any blurriness in the picture), adjust the aperture until the camera meter indicates correct exposure. Take three shots using this aperture.

Set-up #2 - Moving Subject

Shutter Speed Examples - The camera can be any distance from the subject (a moving car). Pre-focus the camera on the spot in the road where the car will be. Set the shutter speed to 1/15 of a second. Adjust the aperture until the camera meter indicates correct exposure. Holding the camera stationary, take three pictures of a moving car.bike, person running, etc..

With the exact same settings ( 1/15 of a second, whatever aperture you metered to) take three panning pictures of a car. A panning shot is one in which you move the camera with the subject "as" you release the shutter.

Do the same thing again, only this time set the shutter speed to 1/250 of a second, adjust the aperture until the camera meter indicates correct exposure. Hold the camera stationary, don't pan.

Set-up #3

Create a really nice image using your new shutter/aperture skills. Subject and technique - your choice.

 
 TURN IN:    
 

1 - Wide aperture/narrow DOF-(small f - stop number) - (write exposure in the file name) - subject sharp/background out of focus
1 - Narrow aperture/wide DOF- (large f - stop number) - (write exposure in the file name) - subject sharp/background in focus
1 - 1/15 of a second holding the camera stationary (write exposure in the file name) - everything blurry
1 - 1/15 of a second panning the camera (write exposure in the file name) - subject pretty sharp/ background motion blur
1 - 1/250 of a second holding the camera stationary (write exposure in the file name) - subject and background sharp
1 - Create a really nice image using your new shutter/aperture skills. Subject and technique - your choice.

You will be turning in a folder named "yourlastnameAS". In the folder will be five files named their exposure setting -example f8-1/125.jpg Put the folder in your Photo folder on your student storage.

 
 EVALUATION:    
 

Your assignment will be graded using these criteria:

From Mr. P's Photo Rubric

Vision:
Is you image original, innovative and daring, or just another example of the same old thing? Does it fulfill the requirements for the assignment (see assignment requirements above) ?

Aesthetics:
Have you used the appropriate elements and principles of design that would enhance your photograph or did you just shoot what was in front of the camera? Have you used good composition or did you just place the center of interest in the center because it was easy?

Mechanics:
Camera Techniques: Is the image sharp/in focus? Is the exposure correct? Was the appropriate aperture/shutter speed used (if applicable for your camera), did you find the best angle?

Computer Techniques: Is the image sharp/in focus? Is it resized correctly? Is it color corrected and sharpened?

Presentation: Is the artwork presented in a professional manner as outlined in the assignment?

Good luck
