In this article, I am sharing with you another light source referred to as Continuous Light. With this light source, it is fairly easy to work on different angles and positions as you immediately see where shadows drop while moving around your subject (you can also move the light source or the subject, for that matter). In this case, as what the name suggests, you have continuous light. Unlike the use of a Mono Light or Strobe light that comes by a flash, you will have to do a few test shots to identify where your subject is lit as desired and where shadows fall.
A number of professional-level continuous lighting solutions are available in the market including special single and multi-socket CFL light banks, high-output LED panels, and various halogen and tungsten lighting fixtures. All these have their pros and cons.
For instance, large CFL (Compact Fluorescent Light) fixtures use several lights and take up a lot of room when compared to other types of lighting. Outfitting such a fixture with several CFLs will also not be cheap. Finally, CFL lights are not generally suitable for use with dimmers, so adjusting a light’s intensity has to be accomplished by adding or removing individual CFLs, with modifiers, or by changing the distance (which also changes the quality of light) from the subject.
