Notes on Flash Lighting Photo Shoot from ALZO digital



FLASH LIGHTING PHOTO SHOOT
Recommended for large object imaging


Flash lighting requires a trigger connection between the camera and the light(s). This connection could be a "sync" cord connected to the camera and to the "key" flash light or a wireless trigger is a more modern and friendly method of flash triggering. If your digital camera does not have a flash trigger output or "hot shoe" you can use the "built-in" camera flash to trigger a "slave flash". The results of this method are inconsistent and often problematic with reflections and hot spots.		If this is your only option, use some black tape to partially cover the on camera flash so that it is greatly reduced in power. Following these set-up procedures will shorten the time to perfect flash usage. Always use "exposure bracketing" for each shot.
		FLASH KIT with 2 LIGHTS Shadow reduction: Good The "key" light with umbrella is placed to the right of the camera facing the subject about 10' away. The "fill" light is positioned to the left side of the subject and is higher and pointing down on the subject, also about 10' away. The camera "sync" output is connected to the key light sync input via a sync cable. The flash on the camera is disabled. The flash of the key light will trigger the fill light. Leaving the key light in place move the fill light to alter the shadow and highlighting effects.

		FLASH KIT with 3 LIGHTS Shadow reduction: Better Adding a "back light" positioned high and aimed down on the background will further reduce shadows. Back lights typically do not use an umbrella, they use barndoors to control where the light falls. Barndoors on the back light typically will be used to mask the light from falling on the subject and they allow the light to fall only on the background.

		Exposure Bracketing Bracketing is a technique used to take a series of images of the same subject at a variety of different exposures that "bracket" the "auto" or metered exposure setting. These exposures are typically over and under the auto exposure setting of the camera. Some digital cameras provide an "Auto bracketing" feature and will automatically take multiple exposures as a burst of 2, 3 or 5 frames with exposure settings of anything between 0.3 and 2.0 +/- EV difference. We strongly recommend using this feature in flash digital photography.
