Aperture

 What is aperture?

Aperture is the setting that controls the depth of field as well as the amount of light that enters your cameras lens. There are three factors to take into account that affect your aperture; focal length, focal distance and f-stop. When using a higher aperture such as f/16, the lens will be more narrow and therefore allow less light in. The higher the aperture is, the deeper the depth of field will be, which means more of the shot will be in focus. Where as when using a lower aperture such as f/2.8, the lens will open more and therefore allow more light in. The lower the aperture is, the shallower the depth of field will be, meaning the foreground of the shot will be in focus but the background will be blurred.

Lower apertures such as f/2.8 are used for mainly close ups where the focus of the viewer needs to on something specific. Medium apertures such as f/8 are used for mid shots and wide shots so as the subject and their actions may be in focus, but the viewer wont lose the main subject in the shot. Higher apertures such as f/16 are used for establishing shots so as the foreground and the background is all fully in focus and visible to the viewer.

F-stop

F-stop is the setting on the camera that allows you to alter the depth of field. Using f-stops of f/16 and higher, the lens becomes more narrow which lowers the amount of light that hits the sensor, whilst this effects the exposure, it also makes the depth of field deeper. Where as using low f-stops such as f/2.8 allows the lens to become wider, letting more light hit the sensor and therefore making the depth of field shallower.

Focal distance

Focal distance is the physical distance between the main subject and the camera. The closer the subject gets to the camera, the shallower the depth of field will be, where as when the subject allows more distance between their-self and the camera, the depth of field will be deeper.

Focal length 

The focal length of a lens measures in millimetres, the distance between the optical centre and the camera sensor. Zoom lenses allow you to change focal length; if you increase your focal length, you will have a shallower depth of field. A longer focal length, such as 135mm, will result in a narrow angle of view and will make the subject seem bigger. Whereas a shorter focal length, such as 24mm, results in a wider angle of view and therefore makes the subject look smaller. Angle of view is how much of the scene the lens will capture.

Client communication

  Initial Client briefing In this meeting we went over the brief with the client, being informed on what the task was, who we were making it for, reputation, messages conveyed and demographics/psychographics we were to appeal to with our video promotion. A video of the meeting is attached bellow to show evidence: Idea pitch In this meeting we, as a focus group, each individually presented our ideas with a basic budget to the client, receiving feedback from client and the rest of the group.  The feedback I received was to follow up with my second idea but to incorporate more family past as well as reconnecting with current family. The client along with the group liked the dialogue "I didn't know you had so much family".  I followed up with this advice, further enhancing my first idea by incorporating contact with family ancestors and connections being made through that. I kept the line of dialogue that was well received. I have. attached a video of the meeting to provide e

British New wave research

What is British New wave British New Wave, otherwise specified as kitchen sink dramas, weren't like the previous typical advertisements for the British way of life, they were unpolished and soon developed into gritty features called "angry young man films". These were typically set in Northern England during the late 1950s and early 1960s. The narratives of these films usually dealt with the problems of the working class, such as: Unhappy marriages alcoholism secret affairs unplanned pregnancies barroom brawls generation gaps Influences/ intent A large amount of British New Wave was inspired by 1940s work of american auteur and 1940s Italian realism. Many British New Wave filmmakers took influence from french new wave filmmakers who used specific techniques to convey realism, such as: Location shots to add documentary feel Real people (not actors) as extras Hand held cameras Black and white footage Reference to the camera men as well as photographers Long tracking shots u

Analysis of 3 promotional videos

Nintendo Switch: Two brothers AD  The purpose of this advertisement is to promote the Nintendo Switch gaming console. It does this by suggesting the idea that nintendo brings people together, even two brothers who never get along and using nostalgia to appeal to older generations. It does this through use of sound, camera and lighting, shot types, editing and misce-en-scene. Genre tropes: how are they/aren't followed Within this advertisement, nintendo, along with many other console brands, use subtle references to games and owned and created by them,so as to show their products. Nintendo puts heavy emphasis on nostalgia and how their past products effected their target audience reminding them that their products have been accepted well from their beginning. An example of this is the scene where it shows the two brothers throughout theirs lives using past products and this being the only time they get along. Where as companies such as Xbox put more emphasis on the mystery behind th
