I Is For Illusions

"It's not an optical illusion
- it just looks like one!"

I have been fascinated by illusions and optical illusions since childhood.
Please excuse the quality of the top photo - it was taken forty years ago! I was mucking about with school-friends, when I spotted the possibility here. So, the snap. I didn't really have a schoolmate small enough to stand on a friend's hand!

Three-and-a-half decades later, I'm still at it, playing with illusions in photo compositions. Here, JJ can hold up our campervan in just one hand! He's strong!


And here, Mr M pats the top of a lighthouse. He's veeeery tall!

Just so you know, this is that lighthouse, shown below. The person at the bottom gives the true scale.


This illusion above is more natural, a rock that looks like an animal. It's the swirl of the water which enhances the illusion, making it look as if the creature is swimming along.

Of course, its the persistence of vision which provides the illusion of continuous motion, the basis of film, movies and animation. Here is a short animation made from still shots of an Escher print. It was an exercise for school; the Photoshop work took all day - the animation compiling took about ten minutes!


There is also illusion knitting, also known as shadow knitting. I've had a try at that, with this top. Directly front-on, there's just horizontal stripes.
At an angle, the vertical stripes magically appear! (must finish it one day ...)


And last but not least, the illusion here - how many rail-tracks are here? The angle of the sun was just right to make this illusion. And I had the camera ready. Oh, the location? Busselton Jetty, in WA. - It's the longest wooden jetty in the Southern Hemisphere - 2 kilometres long.
