Induction task 1 – Considering the relationship between Aperture, I.S.O and Shutter
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. You
must consider the relationship between the 3 settings and work out whilst shooting how the key settings need to
interact to ensure correct technical images.
Whilst shooting always consider;
1.Composition 2. The location you use (background) 3. The aims of the portrait genre 4. What equipment you will
need 5. White balance 6. Directing your subjects, remember they cannot see themselves. 7. Where is your light
source? Can you use it to your advantage, shade, highlights etc.
Stage 2 – Write up and presenting in sketchbooks
1. Define aperture, shutter speed and I.S.O in your sketchbooks 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.Ensure the pages in your sketchbook are correctly titled
3. Only stick in technically perfect images in as your final piece
4. 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.
5. Discuss your strengths and weaknesses surrounding framing, composition, positioning of subject in relation to
ambient light and portrait genre objectives.
