Exercise 2a: Aperture

Exercise 2a.1: Aperture does affect exposure

Exercise 2a.2: Aperture controls Depth of Field

Lecturer:

On week3 we have been told how important of aperture. It can affect exposure and controls depth of field. Most of time we need set F in few numbers such as 4, 5.6, 8, 11, 16 and 22. Every number between 3 little turns. If we just change F but do not change time and Iso, then the picture will become duck. If we change time and F at the same time, as the F become bigger than the background of picture will become more clear. When we change F, there is a line under it then we need change time follow the line until the number become to 0 or the point in the middle.

Instructions for exercise 2:

Exercise 2a: Aperture

Exercise 2a.1: Aperture does affect exposure

Exercise 2a.2: Aperture controls Depth of Field

Upon reading, viewing and discussing the material on aperture, we have come to agree that aperture effects exposure (Exercise 2a.1) and controls depth of field (Exercise 2a.2).

Your problem task for the week is to prove the theory as fact that aperture does effect exposure (Exercise 2a.1) and control depth of field (Exercise 2a.2) by devising a plan and acting on it.

When updating your ePortfolio ensure you describe your plan before showcasing the evidence that proves the theory. Number your images and include the ISO/F/Shutter Speed settings under every image.

All images must be in black and white. Choose appropriate subject matters for your images

Reflection:

Information at the top is incomplete.

Experience:

After the exercise I know more about aperture and how aperture affects exposure and controls depth of field.

Observations:

Each buttons have different functions, we can take picture without use it, but the picture will not perfect .The more functions I learn, then the better picture I can take.

Findings:

Before I think every can shoot but after the class i think only i have more knowledge of photography then I can take a nice picture.
