Experiments in Refraction

Last night at Toft Photogroup, we played with refraction and reflection using Dichroic cubes, CDs and Crystal ball and Cross polarisation.

Refractions and Iridescence in Raindroplets

I was using my telephoto lens (equivalent of 800 mm on full frame camera) to photograph birds but became distracted by the water droplets - their colours and refractions of the backgrounds - twigs or, in one case, barbed wire. Some also show spectral refractions of the low sunlight. Images 3-5 show the effects of moving the focus points closer. 

Creative Fun with Colour

As part of an evening welcoming new members to CCC, I brought along some dichroic cubes and and orange/blue polariser for members to play with. These were my test shots.
