It took me a while to find the right blue and in the end I used a sellotape holder that I have had for so long it even has my name written on it by my mum from when I was a child! That shade of blue is hard to find in nature. I would have used a flower for the red, but I used it for the previous exercise so I varied it with a red bowling pin. The orange is a traffic cone, the yellow some beautiful petals in a bush, the green a clump of leaves and the violet is a coat of mine. For all of these shots I used the auto mode on my camera to take the first one. I then used the manual setting for the second two of each colour and replicated the shutter speed and ISO, just changing the aperture half a stop down and then up each time.
