This video isn't a technical dissertation of gridded light. It’s just inspired by my recent use of the grid (a little circular metal light modifier), and it was Zack Arias who turned me on to those. With minimal gear, these little grids offer up a lot of possibilities. Also note that if you have a monobloc strobe (e.g. white lightening/alien bee), that puts out 250W of light, you can grid that and use it as a continuous light source for video. Nicole and I filmed this whole video that way.
