Shoot a series of photos with each subject to create shallow and deep
depth of field. [Isolated Focus and Everything in focus]
You should try a variety of subjects in varying light and at different
distances to see what effect changing the aperture does to the image
that changing the focal length (Zooming the lens) will affect the changes
in depth of field.
Try the same subject with both wide angle and telephoto zoom settings.
Subject matter is your choice; Your image should include a subject or
subjects that extends over some distance,
you can't show depth of field with a flat subject therefore- Have
something in the foreground and the background.
a tripod, dont move the camera, don't change focus between images,
just aperture and shutter speed.
As you learned in the motion assignment, you have to have the right
lighting to accomplish this.
MANUAL FOCUS- 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. Shallow depth of
field is impossible to get in very bright sunlight . Changing the ISO
to a higher number canl allow more depth of field- Lower number less-
because you can change the aperture (f/stop).
Find a subject that you can get pretty close to that has something far
away in the background. Direct sunlight is too bright to allow shallow
depth of field. Cloudy or shady outdoor light and bright indoor light
should work best. The light in our classroom is just about right. 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.
If you subject is lighter or darker than "medium gray" make
exposure value adjustments to get the correct exposure. Make sure your
white balance is correct.
2) Set up your
tripod and compose your photograph, framing to concentrate on thesubject
and eliminate distracting elements. You will make multiple exposures
at different aperture openings without moving the camera.
3) Set your
camera to "aperture priority" and check the exposure
4) First Exposure
- 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.
5) Second Exposure
-Change your lens opening to the largest opening (lowest number)
like f/2 or f2.8
In aperture priority your shutter speed will change to get the proper
Your shutter speed should be much faster. Make your second exposure.
If the lighting is not optimal, you might have to change the ISO to
use the largest and smallest lens openings.
7) Third Exposure
- Shoot another exposure with an f/stop that fall between exposures
# 1 and # 2.
Make a series of photographic groups of the same subject showing changes
in depth of field.
These exposure groups should be taken from exactly the same position
- they should look the same except for the change in depth of field.
Be sure to check your light meter to avoid over and under exposure.
Make sure you have the correct white balance. Do this with several subjects.
100 additional images (not in a sequence) that demonstrate the effects
of Deep and Shallow Depth of Field
will make a contact sheet to turn in with the original files in the
