The shutter speed on a camera is the length of time the shutter is open whilst shooting. The longer the shutter is open the more light the camera lets in (Moura). If you use a shutter speed lower than 1/60 it is best to use a tripod or some sort of stabiliser as when the shutter is open for a longer period of time more motion blur is capture in the shot. In film the shutter speed should be set at double the frame rate. The frame rate is the number of frames taken in each second. Usually in film the frame rate is set at around 25 frames per second therefore the shutter speed should be set at 1/50 of a second (35mmc). The shutter speed is set at double the frame rate as it helps capture natural movement better. If the shutter speed is too low you will get blurred movement, if you was to record with a high shutter speed everyone within your scene will look like robots, the motion will be very choppy therefore making it look like a stop motion (Devo).
As you can see in these images I have shot an example of a slow shutter speed, a medium shutter speed and a fast shutter speed in order to show the motion blur captured. In the first image I shot with a shutter speed below 1/60 therefore, you can see a lot of motion blur, you may also notice that the shot is brighter as the shutter has been left open for longer. In the second image I have shot with a medium shutter speed of 1/125, there is less motion blur however you still cannot make out the moving object well. The image is slightly darker as the shutter has been letting light in for a shorter period of time. In the last shot I have used a shutter speed above 1/300 therefore the bottles seem still in the image. The photo is darker, when shooting I had to adjust my aperture and ISO accordingly to correctly expose the image.
My Examples of Shutter Speed
I have chosen to shoot footage of cars driving in front of the college, I chose to use cars as they move fairly quickly therefore, it is easy to capture motion blur in the shots. As you ca see, when the aperture is at 1/30, the cars look blurred when they pass compared to the use of a shutter speed of 1/320 where the movement is very steady, when the cars move past we can see them perfectly.

What is 8mm Montage and Why is it Use? The use of montage in film has been used for decades, it creates many creative outcomes which all have a different effect on the audience. The use of 8mm film or a 8mm film look using post production can create a nostalgic home movie aesthetic which connects with the audience and allows them to engage more with the content being shown to them. If creating the home family movie look using post production the use of layers of film damage to give the footage a more vintage, nostalgic look, this is an experimental approach which could produce some creative content. The use of 8mm film footage could be a good way to suggest to an audience the narrative is non-linear and they are telling a narrative happening in the past. The approach gives a very creative narrative which keeps the audience engaged without being too confusing to follow. The use of a montage sequence allows use to reveal a large amount of information in a short amount of time allowi...
Idea No.1 Scene starts with an old warn 24mm film image of a man on the beach kissing his baby's head, photo bridges to the man's son who is all grow up sitting on the same beach with his baby capturing the same photo, as they sit on beach chairs watching sunset, the man uses the app to post the old photo, he writes the caption which appears in a large post bubble above him in the sky, "Dad always said he wanted to make his final steps along this beach, that may not have happened but baby Hayden just took his first steps here today", then underneath he attaches the photo of him and his son next to the photo of him and his dad years earlier and post the memory, the text box in the sky then disappears. A notification box appears showing other people adding posts to the page about the mans father. A high angle close up shows the man feeling proud/emotional after seeing all the lovely posts, he looks up towards the sky The shot zooms out to an establishing shot from an a...
