                                              LIGHTING ASSIGNMENT NO.3

Using the 250 watt halogen bulb in the equipment closet, make a portrait by selecting a quality and direction of light to communicate an emotion that you feel about a person.  Make an additional portrait that reflects the opposite feeling you have about the person.  Explain in writing the laws of light that were at work in each portrait.

In this light setting, I put the only light source over model's head as the main light, and then ask model to hold the silver reflector under her chin to play as the fill light. For the background, black one has been taken over the whole process, because I need it to absorb whole light bouncing from backward.

in this portrait, (actually there is no production photograph) I use the watt halogen over model's head at left with angle 45 dgree and defuser as the main light, and there is a white board on the right next to the model playing as the fill light source. Also, black background was taken in this portrait.
