The relationship between Aperture, Shutter
Speed and I.S.O.
Quiz and induction project.
What type of focus
depth will occur
with this aperture?
What type of
shutter speed will
be needed if you
were capturing an

This is the Canon in built digital light meter. It
currently says +3, what does this mean?
What would you change the aperture to, get the
light meter to 0.

life images of out of
What type of shutter speed do
these images contain?
Write down an aperture F stop which would create this type of visual effect.
Write down the F stop, shutter speed and I.S.O for this Christian Aslund image
which cleverly plays with perspective.
Write down the F stop, shutter speed and I.S.O for this Derek Henderson
image from his body of work which captures abandoned landscapes.
Induction task 1 – Considering the relationship
between Aperture, I.S.O and Shutter Speed.
Objective – To understand and demonstrate how aperture, shutter speed and
I.S.O only work in conjunction with one another, hence, the exposure triangle.
Stage 1 – Practical
Capture three portraits which use the aperture F/22, F/8 and F/4.5, which are
correctly exposed and focused.
Basically, you must prove you can correctly adjust shutter speed and I.S.O to
correctly expose an image when you want to shoot on a certain aperture.
Once you have your 3 images you will present them in
your sketchbook in the following way;
Title – The relationship between Aperture, shutter speed and I.S.O
•1. Include a paragraph which defines aperture, shutter speed and
I.S.O in and discuss how they can change the visual characteristics of
an image. Also discuss they all work in conjunction with each other. If
you change one you usually have consider what you need to do to the
other to ensure correctly exposed images.
•2 Stick in each well printed, correctly exposed stunning portrait
•3. Discuss how you had to adjust the shutter speed and I.S.O
accordingly to correctly expose the image in relation to the aperture
setting. Also comment on the light source.
Leave enough room by each image to….
Reflect on your strengths and weaknesses
1.Composition, rule of thirds, equally balanced etc
2. The location you used (background, distraction or complementary?)
3. The aims of the portrait genre and if you have met them?
4. What equipment you used and could of possibly added?
5. White balance, auto or manual?
6. Directing your subjects, remember they cannot see themselves. Be
honest, did you direct them, was it awkward, did you take your time or
rush, could you have improved the image if you had took longer with the
7. Where is your light source? Can/did you use it to your advantage,
shade, highlights, contrast?
