Whilst using continuous lighting for Portraits may initially look easier than using flash, there are advantages to using Flash over Continuous lighting.

• Flash is less harsh than Continuous lighting, ideal for soft skin tones.
• Tungsten/Halogen Lighting is hot and extended exposure to this will "melt" your subject.  This equates to an unhappy client or a model in constant need of touching up their make up.
• Body Language - When we see a person that we are attracted to, our eye pupils automatically dilate - the opposite is true if you don't like them!!  Bright Lights contract the pupils - the same as not liking somebody.  Look at the two pictures below, the Left one is taken with flash and she looks soft and attractive, the right picture is taken with continuous light, an although an attractive lady, she appears "cold & false".
