The Brief for this exercise was to take an images where the exposure was varied from -1 stop to + 1 stop in half stop increments with a predominant colour filling the frame.
The object of the exercise is to demonstrate the strength of the colour and how it can be varied by changes in exposure.
My first problem was the camera, it is set to change in third stops so after messing around in the depths of the setup I found the option to force the camera to change in half stop increments, I prefer the third stop setting for normal use as it gives a finer control however the exercise calls for the half stop setting so I duly changed it and headed out looking for a subject.
Red is a strong colour and demonstrates this principle well as the changes are quite noticeable, I tried a blue subject which did not work anywhere near as well as this post box so I settled on these images for the exercise.
You can clearly see the image getting brighter as it is stopped up and the strength of the red changing as it gets brighter, stopped all the way down it tends to black stopped up it tends to white, so clearly there are some implications for exposure and creativity attached to the exact exposure used and its connection to the colour in the frame.
