Default Backlighting - Polarizers

An archive shot. Light source is a light table on which I put a polarizer, then a clear plastic object (in this case, it was the cover of the filter case). Then I put another polarizer on the lens I was using. I didn't use black paper or anything to get the black background - two polarizers, when turned to block light at opposite angles to each other, will make things black. The clear plastic object bends the light going through it so some of that light gets through the second filter. It's fun to play around this technique, I've seen some quite brilliantly done shots of clear plastic tableware (forks, spoons). I didn't have anything quite so interesting and was using two filters instead of a polarizing film, so my subject had to be small.

That's definitely an unusual approach to the theme.
Pretty nice results. As you noted I guess this could get real exotic depending on the object being photographed.

Not so sure about this one.

The subject isn't the greatest, it was about all I could come up with that was clear plastic. It was very interesting to learn more about polarizers and the nature of light, to see how this actually worked that made the afternoon I spent playing around with this worthwhile.

Cool effect mtngal

Thanks for generously sharing the detailed set-up.

Inspires us to try something similar somtime.

The colours and abstract shape are interesting.

Nice job, Mtngal. You have just broken the ice on a challenge I've been considering for quite some time. Watch for it coming up.

Thanks! I actually saw this in a magazine a while ago, something to play with for an afternoon when the weather is lousy. I'll be interested to see how this little exercise could lead into a challenge. I'm always up for spending an afternoon playing around, making simple things into something exotic.
