2011-12-19 (Day 479) More Christmas Decorations

It’s another set of Christmas decorations! This time, it’s three little plastic decorations with little colour-changing LEDs in the base.

Sad to say, it’s a technical aspect that impresses me about these trees. Look at how you see the colour at the edges of the big tree, but when you look at it straight on it is entirely opaque and dark. I guess it’s total internal reflection, but the way you can have the light travelling through the plastic, yet you can look at it 90 degrees on and see none of the light… that’s clever!

Technical details: Canon 350D with kit lens and eBay magnifying filters.
