Unit 18: Cinematography

Three point lighting system consists three elements. These are back, key, fill light. Back lighting is where you place the main source of lighting behind the subject to show their features and make them stand out from the background. Key lighting is the main light source in a video and this is placed opposite to the fill light. The fill light is there to fill any unwanted shadows on your main subject in shot.  Light emitting Diodes (LED) are used in filming as that are easily battery powered meaning they are easily portable and can be versatile where you put them. Also they will allow your camera to capture all the colours of scene easily. These are used on cameras as it can help photographers have lights ready wherever they need the camera. Hydragyrum medium arc-iodide lighting (HMI) is used mostly on set when filming with sunlight. This makes filming in daylight easier as the lights that they are used can compete with the brightness of the sun. as they emit ultra violet light. To...

A tripod is used so you can record footage without having to physically hold the camera. To set up the tripod, you need to extend the 3 legs equally to whatever height you want to camera to be at and use a tripod mount to attach the camera to the tripod.  Drones are used to take Ariel shots as they can fly in the air. Drones have a camera already attached so you need to turn on the device and use a controller to manipulate movements. 

Fisheye  lenses  give a very wide angle view out of the  camera  to show full landscapes.    This gives a sense of proportion as it can capture something in a 180-degree field of view A telephoto lens allows people to take pictures of a zoomed in    without any blur or grains . This lens is the best lens to use for landscapes photos at 18mm while at 35mm it is good for street view photos and at the short telephoto length of 55mm makes it good for portraits. ​ ​ A macro lens is a special type of  camera  lens that can work with very short focusing distances, taking sharp images of very small subjects.   ​ Portrait  lens has the focal length and aperture to take good looking portrait photos. Although this the best lens to work you can also use several other  lenses .  ​  

A boom pole is used so that the camera crew can use a microphone without actually having it visible in the scene. A microphone is attached to the end of a pole which is placed in a position where the actors audio can be picked up.  A microphone is needed to hear the actors voices clearly which will make for a much better product. Microphones pick up sounds and turn them into electronic signals to send them through a recording so speech is clear to understand. 

You can manually change many settings using the Canon camera to adjust the light exposure such as Aperture, Shutter speed and ISO.  Aperture is the width of the lens and how much light it allows in. It is measured in F/stops numbered from 1.4, 2, 2.8, 4, 5.6, 8, 11 and 16. and the higher the aperture the wider the lens will be so more light can come through.  Shutter speed is speed at which the shutter closes. If the shutter speed is fast, there is less exposure so less light will be in the shot but if it is a slower shutter speed than more light can come in. This may impact the look through the lens as the slower the shutter speed the blurrier is will look when moving the camera. Shutter speed is measured is fractions of second so a fast shutter speed maybe 1/500 of a second but a slower speed maybe 1/2 a second. ISO is the sensitivity of the cameras lens to change how dark or bright the photo. The lower the ISO the darker the image and vice versa.  Frame rates is the am...
