Demo 6 Bare Bulb

In this demonstration we used a single bare bulb (Profoto head pointed up and no reflector). We didn't move the light, subject or the camera. With the use of the white walls, the black curtains, an 8'x8' white reflector, a small gobo (flag), and a shiney silver card we were able to adjust the lighting dramatically. No fancy light modifiers were used either.

Demo 5 Feathering

The idea of feathering is to combat the effects of the inverse square law. A common use of this technique is for a side lit group portrait. By pointing a light source away from the nearest person, the farthest person sees more of the light sources surface that the person closet to it. By angling the light source in the right balance you can achieve a fairly consistent light reading across the group. In this demonstration we used 4 small soft boxes to make up our light source. We then were able to give twice as much power to the two soft boxes furthest away from the background and therefore increasing the amount of light hitting the people on the far side of the photograph.





In the series below, the top two images used feathering up to point more light at Michael and less at Rachel. The face of the Octabank and the Beauty Dish where 4 feet away and the feathering worked. In the bottom two images we moved both lights back to 15 feet which evened out the fall off due to the inverse square law. The quality of the light changed because each light source became effectively smaller.

Demo 4 Various Light Shapers

There were no adjustments to these images except for slight exposure modifications. The contrast differances are due to the light shaper used.
