Apature

The aperture changes the focus of a shot. The larger the aperture e.g F/2 the more light allowed into the image but the more shallow the focus. Shallow focus or a shallow depth of field is when there isn't a lot in focus, meaning if you have a object in focus the background and surrounding area will be out of focus. When the aperture is small e.g F/22 it has a deep depth of field meaning everything or at least a lot of the image is in focus. When the aperture is low it also lets in less light. For the video i used a tripod as i used a telephoto lens, which is heavier and picks ups shakes more. So in order not to have shakes i used a tripod, however some of the panning was a bit jumpy, so i used a warp stabiliser in editing, so the video looks better and smoother.
The screenshot below is of an aperture of F/5, this is a low aperture that has brought in plenty of light so the image is slightly over-exposed.  You can see the shallow focus, as  there is only one section in focus, the leaf at the front and the bushes towards the back are all out of focus.  A shallow focus is used to draw attention to one particular thing in the shot, when used this would show that the particular thing in focus is important to the narrative.

The screenshot to the left has an aperture of F/8 this is a slightly deeper depth of field you can see compared to the F/5 screenshot there is more in focus however there is still party of the leaves out of focus. This aperture is good for shots where there are a couple of characters in shot and the camera needs to focus not them but instead of all the focus being on the characters , there is a little background to give it context, it could also be used to have someone walking into focus.
The screenshot to the left has an aperture of F/22. This is deep depth of field meaning everything is in focus. This is a good example of deep depth of field because of how much is in focus and the shot is correctly exposed. This aperture is best for establishing shots because all the background and everything is in focus.
The image to the right is of my first try shooting. As you can see the shot is over exposed due to the low aperture opening up the lens and allowing more light into the camera and while filming i didn't use a tripod and so the footage came out very shaky. Although it did show the shallow focus well,as the leaves in front are in focus and the background is completely out of focus.
If i re-shot, i would pan slower on a tripod to stop the shakes. so i don't have to rely on the editing so much. I would also change the shutter speed, in order for the scenes to be correctly exposed so that the shots are more effective and we could focus on the aperture.
