This exercise demonstrates how the strength of a colour is affected by changing exposure. These photographs were taken using a shutter speed of 1/125 and the following apertures:-f 3.60,4.00,5.00,6.3,7.10. The hue in the pictures remains the same but the brightness of the colour in the photographs has varied significantly with the changing exposures. As expected the more over exposed the shot is the lighter the colours appears and conversely the more under exposed the shot is the darker the colour appears. This was a useful reminder about how changing the exposure of a photograph can change the brightness of a colour.
