Depth of Field


Aperture adjustment controls the amount of light that enters a camera. One of the side effects is that when a person adjusts the aperture, the depth of field is adjusted. Depth of field is the amount of area in focus.

A small aperture creates a wide (large) depth of field and requires a longer shutter speed. A large aperture creates a shallow (small) depth of field and allows for a faster shutter speed.

The goal of this project is to create four images demonstrating control over depth of field.


1) Content

The content will depend on weather.


Your pictures must represent educational opportunities at Heritage Woods Secondary. There are a number of subjects to choose from; elective areas and regular classrooms, extra-curricular and school events.

Education at Heritage Woods is different from "school life". Do not cover subjects such as lunch, hanging out, cell phones, lockers, etc.

Some possible ideas - studying in the library, working on computers, science equipment, people playing sports, musical instruments, art supplies, a teacher teaching, working on math, reading a book, ...

You must first obtain teacher permission if you want to take pictures in a classroom, or even of a classroom (from the hall). In addition you must also get permission from anyone in the photo. Flex is the perfect time to take pictures for this project, as you won't be disturbing any classes.

Not Rainy

Your pictures must represent changing seasons. Find subjects that represent changing seasons in a powerful way. We will take pictures outside as a class. Make sure to switch to Av mode, zoom in, and get close to your subject. Not working? Get closer. You can take pictures of your classmates, but only if doing so adds to the artistic appeal of the photo.

2) Skills / Technical


  • adjusting the aperture

3) Elements and Principles of Design

There are numerous elements and principles of design. This project we will be focusing in on value, emphasis, perspective, and balance.

Value: This is the difference between light and dark in an image. Draw attention to your subject by controlling how light reveals form. Try to make sure you have some white and some black in each photo.

Emphasis: is creating an area of focus. This principle is sometimes called dominance. Control the movement of your viewers eyes by creating an area of emphasis. You can do this with lines, colour, value, perspective, shapes, and repetition.

Perspective: is your point of view. Looking up, down, or at an angle. Looking up at someone shows reverence or respect. Looking down makes them seem smaller, weaker, or less important.

Balance: is the distribution of the visual weight of objects, colors, texture, and  space. If the design was a scale these would be balanced to make the image feel stable.

In symmetrical balance, the elements used on one  side of the design are similar to those on the other side; in asymmetrical  balance, the sides are different but still look balanced. In radial  balance, the elements are arranged around a central point and may be  similar.  

4) Creativity / Originality 10 marks per photo

Try to look at the camera angles and lighting conditions. The more that you incorporate previous techniques, then the more likely you will be challenging the level of originality.

5) Professionalism

Professionalism is based on the attention paid to the accurate and careful presentation of the final project. Hand-in your photos to the DOF handin folder.

Photos should be 9.5 inches on the longest side and 180 resolution.

Name your photos as follows:

    1. username_dof1
    2. username_dof2
    3. username_dof3
    4. username_dof4
  • you must NOT over manipulate the images.
  • images must be 180 dpi
  • images must be jpg format
  • Images must have a frame.
  • Add a title outside the frame: lower center
  • Add a date outside the frame: lower left
  • Add a your name outside the frame: lower right
  • Typed evaluations of photographs, written in Google Docs journal (see below)

6) Journal Entry

This journal entry requires you to record important details about each picture that you took. Answer the following in your journal for each picture:


File Name:

Note: For white iMacs - use Command (or Apple key) and the letter i (Command-i) in iPhoto to get this info. For MacBooks and silver iMacs - Option-Command-i


Shutter Speed:


E and P of Design: Which Elements and Principles of Design are present in your image?

Creativity / Originality: What are some of the creative aspects of this photo? Two sentences.

Self-Evaluation: What mark do you deserve out of 10 and why?
