Film Language- Lighting

So far, i have learned a range of things about the different types of lighting there are. For example, i learned about low key lighting, and high key lighting which will be extremely useful in the production of my thriller film. 

• Low Key Lighting:   This will come in handy when trying to create dramatic effects and emotion in my film, due to the fact that low key lighting creates sharp contrasts and distinct shadows. It is created by using key and back lights.
• High Key Lighting:  This will be useful in my thriller when i want to make it look realistic, due to the fact that high key lighting gives a natural, realistic effect. This is created using filler lights. 
• The Key Light:  The key light is usually the brightest and the most influential.
• The Back Light:  Helps counteract the effect of the key light, which makes the character look 'rounded'.
• The Filler Light: Helps to soften the harsh shadows that key lights and backlights create. There are usually more than one filler lights.

An example if low key lighting. The distinct shadows and darkness create a dramatic effect.

An example of high key lighting. The use of filler lights means that there are no distinct shadows anywhere, and the  woman looks a natural colour. The picture also looks realistic, unlike the photo above.
