Rembrandt

• Rembrandt lighting is carefully planted background lights. It is good for specific area lighting and can help make shadows look transparent. This way, the background will still be kept dark except for the elements you want to be seen. Using a back light behind the subject is optional. However, placing a key light off to the side front of the subject is mandatory.
  
  

Cameo

• Cameo lighting is directional spots on a subject with a back light and dark background. With cameo lighting, shadows will appear more dense. As with Rembrandt lighting, cameo lighting requires a key light in front of the subject with an optional back light behind the subject. However, to make this different from Rembrandt lighting, you are focusing the light more directly in front of the subjects.
  
  

Flat

• Flat lighting is done by using highly diffused floodlights such as scoops and soft lights. It is non-selective and has omnidirectional illumination, with the light being fairly evenly distributed. Flat lighting often uses reflectors or soft lights for the key and fill light functions. However, the back light is always present behind the subject with the fill and key or reflectors -- and soft lights are in front and off to the side of the subject.
  
  

Silhouette

• If you're trying to create a silhouette, you need to evenly light the background using floodlights with no illumination on foreground subjects. You will not see a shadow, but your subjects will look like a dark cutout. To achieve silhouette lighting, do not use a reflector.
