Cross Polarization

Hi, thanks for dropping by. I decided to document this part of my learning process, i will be updating this page as i move forward with improving this cross polarizing setup.

So, recently i received my linear polarizing filter from the U.S.A. I bought 1.2 metres of it, which equals 4 units/feet to fix in front of my 2 softbox light sources. Since the filters aren’t as wide as my softboxes, i made a simple cardboard casing with a reflective material on the inside, so i wouldn’t lose any light and still polarize it all. And the reflective material also reduces the risk of the whole thing being accidentally set on fire – the casing is cardboard after all.

On my camera i use a simple Hoya circular polarizing filter.

Well, it works.

Turning the circular polarization filter on my camera to snuff out the unwanted light rays.

The front of one of the makeshift filters.

It consists of 7 cut-out cardboards parts, fully duct-taped together for sturdyness. Since the duct-tape is slightly reflective, i’m worried it will make some reflections. Will replace with something else.

The back. You can use alu-tape or tin foil. I used it for 2 main reasons: heat resistance (i still use those ‘saving lamps’, which can get quite hot after a while) and retaining all the light my lamps have to offer.

Here i’ve placed the filter over my softboxes.

I had to place it so that i had no other light sources interfering and creating reflections.

Even covered my light-tent with cloths.

And yes, i used my kid’s chair to place my tripod on.
