APERTURE

The aperture of the first clip was F4, which means a moderate amount of light is being let into the lens. Because the day was fairly sunny, and I was filming in a shady spot, the image did not need too much or too little light let into the lens. The effect of having it set at a wider aperture such as F4 gave the image a shallow depth of field, putting subjects directly in front of the camera in focus, and everything behind it, out of focus. This technique is used to draw attention to a subject in film.

The second clip is is F8, a smaller aperture opening, allowing less light. I chose a location that had high contrasts of light to illustrate the difference. The light behind the leaves compared to the shadows on the tree trunk indicate that less light is being let into the lens. Another effect of this is a wider depth of field than the F4. This is shown as I switch focus between the leaves(closer to lens) and the trunk(background). The switch in focus is not as bold as the F4, and at times both subjects are mostly in focus.

The final clip shows an aperture of F22 which was the smallest aperture on the camera. This extremely small aperture lets in the least amount of light and so to compensate I chose a very bright shot and switched focus between the water and the wood around it to illustrate the extremely wide depth of field. This however did not work because the subjects were so close to each other so did not accurately illustrate the wide depth of field.

If I were to do this again, I would have chosen a better subject for the final aperture, as it did not accurately show the effect of the final aperture.
