Using artificial light to your advantageStudio and Location Lighting
“Light can be hard, soft, wrapping, harsh, slashing, sumptuous, glowing, etherial, muddy, muted, brash, poppy, brassy, contrasty, clean, open. It’s a little nuts.” - Joe McNally
Text
Quality light is seldom available - fact.
Studio and location lighting allow photographers to add quality light where there may not be good light.
Flashes
We’ll discuss two types:
1. On-camera flash
- Built-in flash and external flashes
2. Off-camera flash
- Studio flashes or strobes
Beginners light kit
• Hot-shoe mount for external flash
• Cable attaches camera to flash
• Built into most professional cameras
Sync Terminal Adapter (Hot Shoe to PC)
Studio Accessories
• Sync Cable and Hot Shoe - connects strobe to camera
Advanced light kit
• Pocket Wizard allows for remote firing of flash (no cables needed!)
Pocket Wizard Plus III

High 45 degree lighting - Rembrandt lighting, more texture and depth
Direction of Light
Side lighting - Harsh 90 degree angle, dramatic and high contrast
Top lighting - Directly overhead, long shadows, not flattering but interesting
Direction of Light
Back lighting - Also edge or rim light, shows smoke well
Bottom lighting - Light from below looks unnatural, works for some products
The Point and Shoot effect

D.I.Y. Flash Diffusers
• Use index cards, printer paper, or old film canisters to help soften and diffuse direct flash
Two important concepts for flash:
1. Inverse Square Law
2. Sync Speed
1. Inverse Square Law
• Light spreads and diminishes as it travels from flash to subjectAccording to the law, the power of the light will be inversely proportional to the square of the distance. So if we take a distance of 2 and square it, we get 4, the inverse of which would be 1/4 or rather, a quarter of the original power – not half.
Remember that each one is simply the distance squared, over 1.

2. Sync Speed
• 1/250 is the max shutter speed most cameras can use with flash
• Any faster and the shutter curtain will be visible in your frame
- Flash helps freeze action
Underexposing with Flash
• Use ambient light to your advantage
• Underexpose then add flash for a dramatic look
Underexposing with Flash

Ambient light is always taken into consideration when using flash
