Assignment 5 – EXPLORING DEPTH OF FIELD
1. Review your camera/lens manual to learn about:
a. Aperture priority mode
b. Minimum/maximum aperture available in camera/lens
2. Adjust your camera to following settings:
Camera Mode Aperture Priority
Focus Point
Set as appropriate for subject and composition.
White Balance Set to Auto White Balance (AWB).
ISO ISO setting to auto, if available. This will allow the camera more
freedom in finding a good exposure. If you need to set the ISO,
choose 400 as a general-purpose setting. (If you find you are
getting blurry images in the exercise in lower-light situations,
increase the ISO setting.)
Exposure Compensation Set as needed for your camera/lens.
Histogram “On” for review.
3. Set up a scene in bright, indirect light which includes a subject you can move relative to the background. Your subject could be something like an object placed in a window sill (not in direct sunlight), or a person in front of a building.
a. Exercise 1 – Investigate the effects of aperture on depth of field.
i. Set your camera to the longest focal length available (maximum zoom). Ensure your
composition includes both subject and background in the frame (you may have to step
back).
ii. Start by setting your camera to the widest aperture (lowest f-stop) and take a photo.
iii. Increase the aperture by one or two f-stop settings and take the same photo again.
iv. Repeat the process, working through the range of apertures available. NOTE: If you
cannot set your aperture with your camera, change between the Normal, Portrait and
Landscape modes.
b. Exercise 2 – Investigate the effects of focal length on depth of field at a set aperture.
i. Set your camera to the widest aperture (lowest f-stop), or on Portrait mode if aperture
cannot be set.
ii. Start by setting your camera on the shortest focal length (lowest zoom) and take a
photo.
iii. Zoom in to the longest focal length and take the same photo.
c. Exercise 3 – Investigate the effects of subject-to-background distance on depth of field.
i. Set your camera to the widest aperture (lowest f-stop), or on Portrait mode if aperture
cannot be set.
ii. Start with a long subject-to-background distance and take a photo.
iii. Reduce the subject-to-background distance and take another photo, trying to keep the
same composition for the subject.
iv. Repeat the process until the
subject is right in front of the
background.
4. Download and review the images on the
computer. Notice the differences in the photos as
you varied the depth of field. Observe the depth
of field in the photos you find most interesting.
Look in the properties of the file to find the
aperture settings for each image.
5. Pick two or three of your best shots. Open these
photos in your photo editing software, and make
adjustments as learned in previous chapters –
color, exposure, composition. How do these
adjustments enhance the photo? Which image do
you like better – before or after the change?
Make a few notes on what you like about each,
what caught your eye. If you would change anything next time,
make note of that too.
