Below is an interesting optical illusion that I modified to fit the color scheme here. At first glance you may see four colors: black, purple, green and blue. In fact beside the black there are only two colors.
Hurricane Katrina was a nightmare for so many people along the Gulf coast including Marie of Mandeville, LA. Fortunately her house came through it just fine, but they did experience the brunt of a major storm.
Out of that storm this illusion was born. This is a picture of her husband standing against a large pine in their yard. She was kind enough to send this to me to share with y'all here.
So tell me why is this picture here on an illusion blog?
Below is another excellent example of White's illusion.
This is an interesting effect, below there is only one shade of purple. Let me be clear both shades of purple have an RGB value of R 198 G 173 B 231.
Although the purple on top seems to be darker than the purple below, they are actually identical.
As you can see, the purple triangles on top are mostly surrounded by blue, while the purple triangles below are surrounded by white. The color triangle's surroundings are changing their perceived color.
The below is the January 2nd, 2006 Astronomy Picture of the Day.
This is another amazing illusion of nature. There was no special filter used to create this effect. Have you ever seen this effect as the sun sets?
Explanation: Have you ever seen a sun pillar? When the air is cold and the Sun is rising or setting, falling ice crystals can reflect sunlight and create an unusual column of light. Ice sometimes forms flat, six-sided shaped crystals as it falls from high-level clouds. Air resistance causes these crystals to lie nearly flat much of the time as they flutter to the ground. Sunlight reflects off crystals that are properly aligned, creating the sun-pillar effect. In the above picture taken late last month, a sun-pillar reflects light from a Sun setting over Bangor, Maine, USA.
Here is an excellent optical illusion photograph taken by Alain db of the Konica Minolta Users group on PBase.
This is an actual photograph not a digital/photoshop manipulation. The best that I can tell is the only thing done to this image was to convert it to Black & White. This photograph was awarded 1st place in Minolta Challenge #16 on PBase.
How do you think it was done?
Could a magnet be holding the King to the side of that raised block?
