Another week at the club with something I have never tried this week. The subject we were exploring is called cross polarisation and it finding the hidden colours in ordinary plastic household items. To get the colours to show the light source has to be polarised and then using a circular polariser filter in the camera lens adjusting it until it produced a black background with the array of colours showing in the plastic. The plastic items I used were clear plastic. I think I will be visiting this again at home when I can find an interesting object at an interesting angle.
