Plastic bottle - In Explore DSC_2494
PET (polyethylene terephthalate) plastic bottles twist polarised light, but you need a second polariser on the lens to see the effect with a camera.
Taken with a Helios 44M at f/8 on about 20mm of extension tubes, and a CPL filter. The polarised light source was an LCD computer screen.
In PP, I've given this a square crop and increased the brightness and black point.
I gave myself the additional challenge of doing this in one shot with no retakes; it made me a lot more careful when setting up, as I have a bad habit of rushing things.
