Aperture

f2.8 moving from Jakob Morrison on Vimeo.

This was shot with an aperture of f2.8, the foreground is in focus but the background is completely out of focus, as the subject moves towards the camera he gradually comes into focus, I felt like this shot displayed just how shallow the depth of field is when using an aperture of f2.8

This was shot with an aperture of f2.8, as you can see the foreground is in focus but the background is completely out of focus. The shot using an aperture of f8 looks almost completely in focus when compared to this shot.

f22 from Jakob Morrison on Vimeo.

This was shot with an aperture of f22, as you can see both the foreground and background are in focus. Comparing this shot to that using an aperture of f8 really allows you to see just how deep the depth of field is when using an aperture of f22.

f8 Standard Lens from Jakob Morrison on Vimeo.

This was shot with an aperture of f8 using a standard lens, as you can see the foreground is in focus but the background is slightly more blurred and out of focus. The difference between the foreground and background is nothing in comparison to that caused by an aperture of f2.8

Process

The numerous shots produced are effective in showing the difference between differing aperture settings. I struggled with this at first and wasn't entirely sure how to change the aperture and wasn't entirely sure I had done it right.

Problem Solving

I found that some of my shots were under exposed as the aperture had been increased meaning less light was reaching the lens, to combat this I increased the ISO, which increased the camera's sensitivity to light and as such meant the final shots produced were exposed correctly.

Justification of Decisions

Recommendations

If I was to reshoot, I would definitely use rack focus within my video to change the focus from the foreground to the background as I feel this would have demonstrated the effect on using different apertures more effectively.
