Readings were taken at the same spot in each image of Hue(H), Saturation(S) and Brightness(B) and Red(R), Green(G) and Blue(B). The readings are provided after each image
The first image was taken at f11
H 228; S 2; B 88. R 223; G 224; B 228.
The second at f14
H 230; S 3; B 75. R184; G 183; B 189.
The third at f16 (this image is taken at the exposure as established using the camera's built in exposure meter.
H 266; S 4; B 67. R 165; G 166; B 171.
The fourth at f20
H 240; S 4; B 58. R 140; G 141; B 146.
The fifth at f22
H 220; S 3; B 38. R 94; G 98; B 99.
From the readings of the RGB scale the colour is largely 'neutral' and remains so throughout the changes in exposure. As one would expect the brightness(B) readings show a smaller number as the exposure decreases.
