Project: What makes colour

Part 3:Colour

Exercise

Control the Strength of a Colour

For this exercise I had to find the average exposure setting of the object below and then take a sequence of photos adjusting the cameras aperture while the exposure stayed the same.The difference in the colour from the first shot taken at an aperture of F4 to the last shot taken at F7.1 are quite striking. The colour has changed from a light pink to more of a dark crimson by just adjusting the aperture.

What is also apparant is the change in colour of the background from an slightly off white colour  to an almost beige colour.

Exp time = 1/80

F/Stop = F4

Focal length = 70mm

ISO =500

Exp time = 1/80

F/Stop = F4.5

Focal length = 70mm

ISO =500

Exp time = 1/80

F/Stop = F5.6

Focal length = 70mm

ISO =500

Exp time = 1/80

F/Stop = F6.3

Focal length = 70mm

ISO =500

Exp time = 1/80

F/Stop = F7.1

Focal length = 70mm

ISO =500
