Paramecium under polarized light

[NikonUser]

I wasn't going to post these as I was expecting better images but as Chris posted his excellent image of a P. bursaria inder partially polarized light

I thought it may be worth comparing with Chris' specimen.

I tried all combinations of polarization with my set-up: Olypus simple polarizing attachment BH2-KP that includes a rotatable substage polarizer, a 1.25x intermediate tube with another polarizer (analyser), and a 530nm wave plate.

These 2 are perhaps the best, both with all components in place; in the top image the greenish background was changed to neutral grey.

Live, active fellow in too deep water; single frames. 20x + 1.25x + 2.5x, flash
I was hoping for more clarity, perhaps different colouring, of the internal bits. Cilia came out OK.

Thanks for feedback.
Your images look very good, with crisp detail.
It seems that this specimen doesn't contain to much birefringent crystals, usually seen as shining points under crossed polarizers.

Very nice! I actualy prefer this type of shot for these animals!
