"Cumulus in a can... You can buy anything these days! :) "Despite appearances this image was not photoshopped. I have heard people point to the fact that the sky is a different color blue around the can as proof. To those I would only point out that that is the way the sky is with light fluffy clouds floating around. Besides you can go to this large image and take a closer look.
According to the IMDB the plot is "A troupe of Japanese acrobats perform various stunts in front of the camera." They further state that Segundo "Joined Pathe Laboratories in 1901 where he specialized in adding color to film."Yes this was created and hand colored in 1907.
This is a wonderful photo because there was no photo manipulation done to this what-so-ever. The Welsh hobbyist photographer and artist Twm says of this picture, "My younger brother outside Howells department store Cardiff"
This famous illusion is very effective in this example. The tiles are all square and all horizonal lines are parallel to each other. The history of this can be read here in a previous post.
"Over the Christmas holiday of 2001, I was reading "Escher on Escher" and became taken with the notion of attempting to create a computer model of the subject of one of my favorite Escher illustrations--the cluster of buildings in his work entitled "Ascending and Descending". This was one of what have been termed his "Impossibility Series"."John also provided a little peak behind the scenes of this image. You can check out a video clip that let's you walk around the stairs just as if you were one of the monks. This allows you in on a little secret of how this optical illusion was accomplished in a 3D model.
"Public infrastructure projects are notorious for taking longer than expected, but Germany's new water bridge tying the Elbe-Havel canal to the important Mittelland canal, which leads to the countryÂs industrial Ruhr Valley heartland, was over 80 years in the planning." Read more...
WikipediaIt can be a very strong illusion at first. Trying to line up the top and bottom lines so they meet can be tricky. Most of us though will not be fooled for long and some may not be fooled at all. I can align the two lines just about every time now. It has reached the point that I doubt if it will be a challenge for anyone. Maybe it never was a strong illusion, sometimes my memory plays tricks on me. This illusion seems to be stronger with kids.
The Poggendorff Illusion is an optical illusion that involves the brain's perception of the interaction between diagonal lines and horizontal and vertical edges. It is named after Johann Poggendorff (1796-1877), a German physicist who first described it in 1860.
About the contest
"The contest is a celebration of the ingenuity and creativity of the world's premier visual illusion research community. Visual illusions are those perceptual experiences that do not match the physical reality. Our perception of the outside world is generated indirectly by brain mechanisms, and so all visual perception is illusory to some extent. The study of visual illusions is therefore of critical importance to the understanding of the basic mechanisms of sensory perception, as well as to cure many diseases of the visual system. The visual illusion community includes visual scientists, ophthalmologists, neurologists, and visual artists that use a variety of methods to help discover the neural underpinnings of visual illusory perception."
