Set up a frame system with great care. Always have an eye for safety.

FABRICS AND ROADRAGS

There are many different types of diffusion fabrics available. Some are white and some are black, and they have different transmission values. Some come color-coded. Since we use fabrics from all three major sources, we’ve included the following handy chart we use to sort out which does what.

The fabrics have various names. Some are called “cloth”; others are referred to as “scrim.” Many (but not all) of the scrims are black. Scrims are popular for broadcast location shoots. When the depth of field must be shallow enough to focus on a reporter, you can reduce the background light intensity by setting up a frame covered with black scrim material directly behind him. If he is standing under white diffusion material, the light will be reduced by a half stop; black scrim behind him will render the background with the same exposure value as for a correspondent doing a “stand-up” report, such as a correspondent filing a report from the White House lawn. These exposure values are easy to calculate based on the chart’s transmission value. Matthews has a kit called RoadRags. Much like a light bank, these are quite compact but, after the limp structural “bones” are pulled out of the kit, with a little encouragement they snap into their functional form and become larger as fabrics are slipped over them. Some users like to apply the fabric before popping the frame open.

Matthews also has a light control kit of pre-assembled “flags”—not to be confused with the materials used for flagging light. These diffusion tools are solid on three sides, with the fourth side open. The kit creates a soft edge that in many cases is tough to detect. Westcott also sells Fast Flags, which are similar to the ones Matthews offers, and like Matthews RoadRags, they can be collapsed. While the frame of a Fast Flag is open, different fabrics can be quickly slipped on and off of it.
