Exercise: Control the strength of colour
Aim: The aim of this exercise is to discover the effect on colour from altering exposure.
Approach and results:
I chose to use an old phone box for this exercise. All these shots were from the same position with similar light. This cannot be guaranteed despite taken the pictures as quickly as I could as the cloud cover was continually changing. All shots were at 1/400th of a second. The apertures were f3.2, f3.5, f4.0, f4.5, f5.6; f4.0 being the original camera meter reading. I spot metered on the red to ensure that this was accurate. The 1/2 stop under exposed shot is not only stronger in colour but, to my mind, a more accurate coluor representation. The more overexposed shots start to become 'red/orange' rather than red.
