Project 30: colour control

Task: Find a strong, definite colour – choose a viewpoint so that the colour fills the frame. Find average exposure setting Take sequence, composed exactly the same. Change the setting by half stop. 1/125 at f4, f4.5, f5.6, f6.3, f8.

f/4, ISO 100, 60mm

f/4.5, ISO 100, 60mm

f/5.6, ISO 100, 60mm

f/6.7, ISO 100, 60mm

f/8, ISO 100, 60mm

I chose to take a close-up photo of my red London Marathon sweatshirt. Using the Aperture Priority setting on my camera, my first image was taken with an aperture of f/5.6. My ISO was at it’s lowest (100) and so a 3 second shutter speed was needed to make the exposure. Luckily my camera was on a tripod so camera shake was not an issue. I then used this setting as the average. I changed my camera setting to manual so that I could have total control over the aperture size and shutter speed. I then was able to keep the shutter time at a consistent 3 seconds when adjusting the aperture.

Reflection – As the size of the aperture decreased (increased in f/stops) the red gradually got darker and the amount of shadow increased. At f/4 the red is so bright that it almost appears pink when compared with the colour circle. I have never thought of being able to control the tone of colour in this way before. When shooting hand-held I usually opt for a wide aperture so that the shutter speed is quicker or to create a shallow depth of field. However my photos would sometimes appear pale in colour, and this project explains in some ways why that happens.  Therefore I will try to experiment with bracketing my exposures in order to get a balance between colour, tone and contrast.
