Background Light Question

I'm not really happy with the effect the snoot on my background light gives me for groups of three or more. I am thinking about trying a grid for that purpose. Would a 40 degree grid be a good place to start or are there other options I should consider?

    It really just depends on how much area on the background you want to be lit.
    I would say a 30 degree would be a good starting point.

    Hope that helps :)

    It's both the area of the background and the distance from the flash/grid/snoot to the background that need to be considered. A single snoot or grid is rarely sufficient to cover all your needs.

    If you know the area to be covered and you know the distance you should be able to calculate the required spread angle. It's the spread angle of the light that is your concern and what dictates a particular modifier.

    If you don't know the required spread angle, we can't recommend any particular device. It would be best to go with a number of devices. If you want to try grids then a set of stacking grids is the safest bet.
