Shutter speed

 Shutter speed, in photography and film, is used to control how movement and motion is perceived by the viewer of said video or photograph. There is, however, a difference between how shutter speed is used and how it effects film and photography. For example in photography, if you were to use a low shutter speed of 1/4  and take a photo of an object moving, the photo will contain a large amount of motion blur and details will be un clear, where as a high shutter speed of 1/500 will take a more clear, concise image that will make the object look like it was still when the image was taken. Whilst in film, the shutter speed does still effect mostly the motion blur, you are more limited on what shutter speed you can use as, to achieve a natural movement look, the shutter speed should always be set to double the frame rate (frames per second) the standard frame rate used in film making is usually around 25 FPS making the shutter speed automatically 1/50. Setting too high of a shutter speed too high in relation to the frame rate will make the footage choppy and can make it look almost like a stop motion. Where as setting the shutter speed too low in relation to the frame rate will create a large amount of motion blur and will do the opposite of recreate how natural movement feels/looks in real life.

Another thing to consider with shutter speed is that it effects the exposure of the footage, the longer the shutter is open the more light is let in, and the less time the shutter is open, less light is allowed in; because of the limited variation of shutter speed you can use in film and still capture an accurate representation of natural movement, means that iso will have to be changed and aperture can be changed to effect the exposure too (however sometimes that is undesirable as it will change the desired effect of shot) and therefore additional lighting or filters will have to be used to achieve correct exposure. 


This image depicts an example of the results a slow, medium and fast shutter speed will have. The image will bee brighter the lower the shutter speed as the shutter is open for longer and therefore lets in more light. ISO, and aperture usually have to be changed according to the shutter speed in order to get correctly exposed shots/footage.

Why would you use a higher or lower shutter speed?:
A lower shutter speed can be used for a variety of creative and meaningful purposes in filmmaking, for example, setting your shutter speed much lower than double the frame rate and therefore having large amounts of motion blur can be an accurate and creative way to convey disorientation or drunkenness, this is because the amount of motion blur created on camera is much more than what we naturally perceive in real life. 
A high shutter speed is mostly used for fast paced, action filled footage. For example, a fast shutter speed would be used in videography for the sports world. This allows as little motion blur as possible and makes the audience feel as though they aren't missing anything.

Carol Vernallis - The kindest cut

 Carol Vernallis' theory revolves around four different concepts, being narrative, diegesis, camera movement and framing and editing. Narrative Vernallis states that a music video is the visual response to a song and its lyrics and therefore the video should support the lyrical meaning along with the music. However, the artist should still remain consistently present. This is to allow the audience to feel closer to the artist, along with identify with the music, this in theory leads to the artist gaining support from new fans. Music videos can, but are not limited to being balanced between narrative and performance, the video can be mostly performance or narrative and still convey a strong meaning whilst appealing to the audience. Vernallis goes on to state that continuity isn't as important in music videos and the narratives may often feel fragmented or unfinished; this is because the focus of the audience should still be on the song and if the narrative followed all basic rul...

Schedule

Image
  Due to me having issues with excel, I have made a listed time schedule rather than a gantt chart, here i have listed all of the tasks I need to. get done, when I should start them and when they should be finished by. Bellow you will find a brief evaluation of how well I followed it. Throughout this project I have completed all of the production tasks on time, however, If I could change anything I would give myself more time to reshoot as I have some footage I wish I could change but could not because of poor weather conditions. I, however didn't complete any of the evaluation by my planned finish date due to organisation problems, next time I would to improve, create a gantt chart so I can more effectively manage my time.

My Film Plan

  Jaques Lacan Key words/Phrases to focus attention on when filming: -Lack of fulfilment -Mirror My main idea My idea is to convey body dysphoria that is experienced by a transgender person. This links to Lacans theory because my characters fantasy of what they wish they could look like feels un-achievable, and due to this they will always feel a lack of fulfilment. I will be conveying this by starting with multiple different shots of the protagonist still looking feminine, wearing makeup and a dress, I will use a variety of shot types to convey their discomfort as the video continues. The protagonist will be shown distressed and taking their make up off, making their hair more "boyish" and changing into less feminine clothes. Even after this character has shown themselves attempting to appear more masculine, they will be shown to feel a lack of fulfilment through showing their maladaptive habits such as smoking and drinking. I will also show the stress of money that sufferin...
