What do you see?

There was a programme on the radio this morning called ‘the light scientific’. I only caught the end of it but it was interesting, they discussion was about human perception. The scientist had been responsible for the gold/white dress or black/blue dress controversy that went viral a few years ago. She explained that when the image was released she had no idea what a massive argument it would cause between people. Her team had taken a black and blue dress but photographed it under a mixture of yellow and pale blue lighting. When the viewer looked at it their brains subtracted the lighting in different ways, and their perceptions were distorted or changed. As she acknowledged some of the different perception could have been due to the quality of the displays people were viewing it on. So they tried the real dress and carefully lit it. People were then allowed to view in real life. Amazingly they saw one or the other versions. The explanation is that we all perceive colours differently. My red could be your orange. Add to that some people are colourblind. Makes for an interesting world.

So what us my image. It’s an edited view of a window on the new twenty pound note. Not a figure in a funny hat (which is what I see).
