    I have a video production truck
    and require 2 filling lights casting
    40 degrees each.

    How affective are barn doors on
    softboxes ? Should i be using a grid
    to direct my desired area ?

    Since i shoot outside primarily
    i seem to be leaning towards
    softlite metal boxed light system
    vs a soft box because of durability
    issues.

    Oh i fig'd out that its not really
    2006 its 2005 my other posting
    is still listed as the newest.

  2. Grids will give you the best chance of actually focusing a softbox. Start
    with a 40 degree grid.

    This may sound like a dumb question but does using grids like egg crates
    just control the area of light projection or does it do that and increase
    the
    intensity of the light projected since its in a smaller area. ?

  4. Using the word "focus" could have been a bad choice on my part. I see where
    it can be interpreted several different ways.
    A cloth grid or egg crate on the front of a light box just gives a bit
    better control on where the light will land when panning and tilting the
    fixture. It does NOT increase foot-candles.
    Cloth grids or cloth egg crates are very lightweight and efficient tools
    that are commonly used to decrease unwanted light spill.
    There can be little bit of light loss and a minor increase in harshness
    depending on the depth and size of the grids. Sometimes, barndoors are a
    better tool. It all depends on the shooting environment, the agreed upon
    look of the shot and the tastes of the DP and Gaffer.

    There are many books and online articles available.
    Take the time to do a google search and read up on lighting and lighting
    tools for film and video.
    Specific questions will never take the place of acquired general knowledge.
    Taking a few hours to read to learn some of the terminology, and the
    performance envelopes of the lighting tools used in the stage/film/video
    production will ultimately save you from many hours and dollars wasted down
    the road.

    i think because of the nature of the softlight, barn doors would not be as
    effective as separate flags or "cutters" on stands. I agree egg crate will help
    make the light more directional. It will reduce your light a bit.
