Lighting setup diagrams

Here you can see two simple diagrams of the lighting set up that I intend to use. After a little research I beleive that these setups will give the desired look that I will be looking to acheive.

Low-Key.
On the left is the set up that I will be using to create a low-key shot. The single light with a difuser over it will cast a subtle ray of light upon ther model stood in the centre. I can also use a reflector to help soften some of the shadows if they apear too dark, but despite this i may like the contrasty look from dark to light.

Low-key lighting is a style of lighting for photography, film or television. It attempts to create a chiaroscuro effect. In traditional photographic lighting, three-point lighting uses a key light, a fill light, and a back light for even illumination. Low-key lighting requires only one key light, optionally controlled with a fill light or a simple reflector.

Low key light accentuates the contours of an object by throwing areas into shade while a fill light or reflector may illuminate the shadow areas to control contrast. The relative strength of key-to-fill, known as the lighting ratio, can be measured using a light meter. Low key lighting has a higher lighting ratio, e.g. 8:1, than high key lighting, which can approach 1:1.

The term "low key" is used in cinematography to refer to any scene with a high lighting ratio, especially if there is a predominance of shadowy areas. It tends to heighten the sense of alienation felt by the viewer, hence is commonly used in film noir and horror genres.

Low-Key(with fill light)Here you can see the other diagram for my lighting setup. This setup is very similar to the low -key set up used earlier. Only with this layout I intend to use a second light as a fill light, this is used to cancel out any of the shadows a single lighting setup would produce. There is also something deifferent with this shot aswell, For this shoot i intend to use coloured gels to cast couloured lights upon the model. I feel when used in conjunction with appropriate props this will help to create the nice looking artistic peice I have been looking for.
