Hello,

I am shooting a Ryerson University thesis film in January. They've got a little more money than the average student film, and the director has very specific tastes about how it should look.

I am having trouble figuring out how to achieve a certain effect that the director is looking for, and I'm not sure where to start. He basically wants to re-create the pattern of light you get when light shines through a chandelier or crystal; varying spots and lines of hard intense light. I could just shine light through a chandelier but I'm afraid I won't have enough control.

The scene is a ballerina dance in a large room with 3 windows. I'm thinking 4ks outside the windows, 2x 1.2ks though a 12by grid cloth and a flathead80 as fill.

Anyway, he wants the sunlight to have that crystal pattern on the floor. Any ideas on what I could hang in front of the light? I don't know much about theatre lighting but I bet there is something that is used for this effect.

One idea was to use a tray of water with broken mirrors in it, shining a light into the tray, and using mirror boards to direct the light through the window. However, this is sort of unwieldy and I'm not sure it would work.



Any ideas??

You would think that you'd have to recreate the aspect of the light being split up into its different color wavelengths. Short of using actual prisms for that, I suppose strips of colored gel may help. But honestly, the director better explain exactly what he wants. The best thing would be to set-up a light shining through some hanging crystals as a basis for discussion. Does he want dozens of little spots in the room? Does he want them to move and dance around? Does he want rainbow diffraction patterns?

You can get something very similar by covering a mirror in clear packing tape and smashing it and bouncing the light off of it. You might try it with a small mirror and see if you like it. You can even bend the mirror to mess with the pattern it makes, to some degree. Just don't cut yourself.

I forgot to mention something. You can get a pattern similar to the broken mirror but more subtle. You just superglue bits of broken clear glass to an unbroken mirror.

I also always gaff tape the poop out of the back of the mirror before smashing it then packing tape on the front. never tried the glue thing, though; good call on that might play 'round with it when I get a chance.

I think the broken glass idea might work perfectly, I'm going to test that. I wonder if Whites has any broken mirror boards they'd donate :P


On a side note- I just found out that Gordon Pinsent is going to be starring in the film :o
