Yes, I know that this is a hackneyed topic, but these workshops have to appeal to both the beginners and the more experienced photographers. I have read many articles about this technique over the years but this is the first time I have tried it.<\/p>\n\n\n\n

In preparation for this event I went around the house looking for transparent items to photograph. These I used along with some objects from other members:<\/p>\n\n\n\n

This comparison is to show how a plastic bag differs under different angles of polarisation. They are of different parts of the bag:<\/p>\n\n\n\n

Food containers differ in how strongly they react to the polarised light. This comparison shows a food container from a take-away to one from a bought set:<\/p>\n\n\n\n

This next shot is a 4-way view of the same set of plastic beads at different angles of polarisation. This is followed by a comparison slider of two of the views:<\/p>\n\n\n\n
