Ryan,
Where do you get your supplies like foamcore, gaffer tape etc? Charles |

you can get white and black foam-core at any wallymart.... and guerilla duck tape is the most hard core black duct tape I've ever used.... spensive, but strong.
I've been a still photog professionally for over 20 years... and foamcore/gator board is a must have in my studio and on location. I've built entire sets with 4'X8' foam-core.... and even a temp darkroom with black gatorboard. ( gatorboard is like foam-core, but with a firmer foam inner.... you can get it as thick as 2" ) |

Diffusion for very hot lights
Find the closest hot air balloon manufacturer and get a few yards of their flame proof fabric. it's a little thicker than regular scrimming fabric, but lots of peace of mind; I have several yards of the stuff, ordered it over the phone from someone in Ft. Worth as I recall; I use it often with my 6" fresnels when I need more soft light, and those babies are lamped at 650 to 1000 watts. I just pull the lenses and slide the lamps to the front (flood) position.
And I'm with the "diffusion's too close in these solutions" camp... even a 3' softbox is just a fairly hard light once it gets a few feet away... nice for closeups, but for broad, soft light, I'm still a believer in hanging big sheets of white fabric from c-stands and using 4x8 black foam to control it. essentially you end up with 4' x 8' softboxes this way, with a big enough sweet spot that talent can really move around, all for a couple bucks. |

The 'source' for your soft light, is the last surface it departs from. That's why the larger the 'face' of the softbox, the broader and softer the light. Hence the need for the actual element to be further away from it. You don't want a concentrated hot spot to show up on the white surface. If you bounce the small soft element onto a 4x8 softcard like foamcore, than you'll wind up with a much softer 4x8 'light' to work with. That's great. Of course the trip TO the surface of the bounce element and then FROM the surface of the bounce element diminishes the intensity of the light. Remember, light falls off at the inverse square of the distance. So it happens exponentially.

How soft is the light from the sand-blasted worklight?
Can you show us pictures taken with this reportedly nice light? Thanks! |

Hey Ryan
Are you saying that the work light/ezfoil/diffuser improv was shone onto reflectors? Did you use foamcore or regular reflectors? Just wondering. Charles |

I guess we'll ever know exactly how soft the sandblasted worklight is.
Is there a reversible way to soften a halogen worklight? I'm thinking of spreading something like face powder over it. Something removable. |

I just wanted to take a second to thank Ryan for his excellent tutorial on making a soft box, I've been using these workshop lights for a few months now but the extent of my diffusing was simply bouncing the light off nearby walls, I'm sure your softbox idea will be much more practical in the future, heh.
