Photography 101 - Assignment 2

Next we learn about the impact of varying shutter speed and aperture on images we create.  Your mission, should you choose to accept it:

1. Choose a subject of interest, with buildings, trees, or other objects showing behind your subject. Place your subject four feet from the camera lens. Using the light meter on your camera, make three exposures. Select and adjust the lens to be wide open for the first exposure (e.g., f/3.5). Use the f/5.6 setting for the second exposure, and f/16 (the smallest opening) for the last.

2. Choose any moving subject (except the usual moving car). Review “Camera Care & Handling” at the Kodak Web site referred to in module 1 and the examples of using various shutter speeds in the text. Direct and photograph your subject to show (a) stopped action and (b) blurred action.

3. Download your pictures or process your film using any film processing service that offers digitization of 35mm negative film so that the images can be displayed on the Web.

4. Review the pictures, and select four (4) images that you feel best demonstrate your abilities associated with this assignment.

5. Post a brief self-critique of your photographic exercise (about 1–3 paragraphs). Describe the photos, how you carried out the exercise, what worked and what didn't, what you like about the photos you selected and what you would like to do differently.

Let’s tackle the moving subject first.  I am fond of flowing water photos, so I set up a stationary sprinkler on the lawn and took two photos.  In the first I used a high shutter speed (1/1000) and you can see the individual droplets of water.

For the second image I wanted as slow of a shutter speed as I could get and properly expose the photo.  By adding a three stop neutral density filter to the front of my lens I was able to get an exposure at 0.6 seconds.  For both shots I used a tripod so the images would have identical composition, but I would have needed one anyway to keep camera shake from ruining the exposure.

I chose a flower pot as the subject for the next set of images and in the background are the railings and random objects on my deck.  Again, I used the tripod for consistency in composition and took image at each whole f-stop on my lens (Canon EF 35mm F2.0 IS USM).  Starting at f2.0 the image shows some blurring of the background which gets clearer up to about f11 and after that the images are very similar.

I really enjoyed the exercise.  My favorite photo is the long exposure of the sprinkler.  There is an ethereal quality to the water trails that I find appealing.
