[QUOTE="Robert Mitchell, post: 112086, member: 11282"] Think of lighting as a contrast control. If you're working with one light, you position that light and create highlights and shadows. You can move the light up, down, left, right to control the contrast and transitions from specular to highlight, highlight to diffuse, diffuse to shadow and shadow to black. If you place your key light and add a fill light (true fill at camera position), you're lifting shadows and decreasing contrast. If you have a strong shadow under the chin you can add a light source or reflector to further lift those shadows, thus decreasing contrast. If you have a small white room and you have a main light at camera left but find that you're getting some return from the right side wall, that is decreasing contrast. You can then subtract light with a cutter or gobo and this increases contrast. Regardless of quantity of light or contrast, you adjust exposure accordingly based on where you want your highlights to fall. This only applies to digital. With film you had so much latitude that you didn't have to be concerned with a blown highlight and it was much more important to expose for the diffuse value.
