Primary and Secondary Colours

I took a wide variety of images over two days and two locations, and chose the below images that are most like the pure colours in the colour circle. Luckily it is the height of summer, and plenty of flowers are blooming, giving me much better opportunities for finding these colours. I was adamant that I wanted to photograph natural colours, and I thought I'd struggle with certain ones such as violet and orange. In fact the colour I could find the least of was blue! Even more difficult was finding a blue that matched the dark pure blue from the wheel.

Overall, I feel my colour-searching was successful. My camera allows me to 'bracket' a burst of shots, where I can specify in the menu a certain degree of exposure compensation, in this case half a stop. With my finger pressed on the shutter release the camera will quickly take a burst of three shots, one at the correct exposure, one under-exposed by half a stop and one over-exposed by half a stop. Once in Adobe Bridge, I compared my images to the colour wheel, and selected the closest matches. For three out of the six images, under-exposing gave the closest match, over-exposing in two of the images, and one image with the correct exposure was the closest.

The final three images show the same exercise with multiple colours. I saw this display in a shop window, and like the texture of the material and the multitude of colours on show.
