Lighting research

There are six different types of lightinbg in the creation of a production- 

Key light- This type of light is one of the most significant lights out of those used by a cameraman. The main function of this light it to highlight the main object on set. This light is usually accompanied by another two lights which creates a 3-point setup. The other two lights which are part of this set up are, the back light and another light which is also used to focus on the main subject of the scene. 

Fill light- The fill light (which is also part of the 3-point setup), has the purpose of lessesning/eliminating both the contrast and the shadows which are being created around the main subject. This is achieved through the sensible placement of the back light. It is usually placed at a different angle to the key light which means it is able to do what it's there to do. Another way in which the fill light is different to the key light is the softness of the fill light. This is because it is softer than the key light which is another aspect which enables the fill light to fulfill its duty. 

Back light- The back light is the light which is placed behind the main subject of the scene. This is so that the subject is illuminated, consequently there is a sillhouette figure which is created. It can also be used to create seperation of both the subject and the background which means you (as a member of the audience) are able to make out the difference between the background and those objects in the foreground can be identified as a result of the use of this light. It also has the capability of creating depth between characters and objects and scenery, this is also as a result of the placement of this light. 

High key light- The high key light is the one which is used to reduce the amount of contrast. This is due to the fact that the lighting is so strong, therefore if the scene is of a happy nature, the background and foreground are not both going to be dark, as dark colours connote the opposite of positivity (negativity). But using these strong lights means that a happy and joyful impression is created in the picture/film. As a result of this they have used this one single light in order to emphasise their intentions of making the scene/image a positive connotation nand not a negative one. 

Chiaroscuro light- This is what describes a high contrast between the use of light and dark in a single picture/scene. The main reson that this is used is to create both depth and volume, this is because it gives the image an effect which almost makes it look embossed. 

Rim light- This light is one which is similar to a bacvk light, this is because it comes from behind the subject. The only real difference is that the light is placed right behind the subject (so that the very edge of the border of the subject can be lit up and made out. The other difference between a back light and a rim light is that the rim light is a strong light which produces a sllhouette with a highlighted edge.
