This exercise is teaching me about varying the exposure. I am able to go ahead with this exercise as my camera is able to override the automatic exposure and this is what i am to demonstrate in the following task.
The exercise wording advised me to find a strong, definite colour and to find a viewpoint so that the colour fills the frame. (I have chosen to photograph a red front door) It instructs me to take a sequence of photographs with the exposure the same and the stops doubling each time.
I have taken the sequence with the exposure setting at 1/30. I found this to be the most effective. I tried both 1/100 and 1/125, however, both of these proved to be under exposed and i didn’t think they demonstrated the exercise well.
My stop sequence is as follows; 1/30 – f4.0, f4.5, f5.6, f6.3 + f8.0.
See my images below.
As you can see from the above photographs they all vary in exposure. However, the richness of the red tone remains. The brightness however, varies from bright red at the lowest f stop to darker/deeper red at the highest f stop. As i have been studying, the difference here is the brightness and not the saturation. These two can be difficult to distinguish which i feel that i have understood and demonstrated well in the above images.
