Studio High and Low key Lighting research

We have already learned the difference between high and low key photography at the college.
previously posted some images using both. As a part of my research for both theme's I'm posting some information on High low key.

High key 
Is a style of lighting that aims to reduce the lighting ratio present in the scene.
High key describes an image composed of mainly light tones and one where the shadows are effectively eliminated. Exposure and lighting influence the effect and photographs usually have pure or nearly pure white backgrounds.
Examples were posted in my previous blog posts.


Low Key
Low-key lighting is a style of lighting creating a dark effect/ tones. Low-key lighting often uses only one key light, optionally controlled with a fill light or a simple reflector.

Low-key is usually dramatic and full of mystery, this type of lighting creates striking contrasts through reduced lighting. Shadows are the primary element of the composition.
Examples were posted in my previous blog posts.
