What Color is this Dress?

Color 28 February 2015 1 Comment

Every now and then, some optical phenomena comes along and creates a buzz.  The current one going around the Internet is being called “What Color is this Dress?”, and it is a pretty good one.  Have a quick look at the picture of the dress below… what two colors do you see on this dress?

What Color is This Dress

Some people see a white and gold dress while others are seeing a blue and black dress.  Me personally, I kind of see a light blue and gold dress, so maybe I’m in a third camp here.  Whatever color this dress is, it has caused quite a stir.  I would be curious to see what colors people are seeing here, so please drop a quick comment and let me know what two colors you are seeing.

Our brains make a lot of assumptions when trying to process the color of an object.  In order to explain what is going on here, it might be helpful to look back at the color saturation illusion and the checker shadow illusion video.

The Cover Up by Erik Johansson

Miscellaneous 26 February 2015 No Comments Yet - Share Your Thoughts

Erik Johansson is an expert at using Adobe Photoshop to take real photographs and turn them into something magical.  The man on the ladder in the photograph below appears to not like the dark and dismal view of the landscape in the background.  So what does he do?  Well… instead of complaining about it, he prints out some banners of a more pleasant scene and hangs them on a wire to completely change the view.  The trick with Erik’s work is that he takes many photographs with the same perspective and lighting and is then able to merge them together such that they look like a seamless scene that could actually exist in real life.

You can view a lot more of Erik’s deceptive photographic work on his website, or have a look at Common Sense Crossing which we posted on An Optical Illusion a couple of years ago.

Variation of the Cafe Wall Illusion

Estimation 19 February 2015 No Comments Yet - Share Your Thoughts

In this variation of the Cafe Wall illusion, created by Alan Stubbs, the vertical gray lines between the black and white squares appear to be quite wavy.  If you take a straight edge (like a sheet of paper or a ruler), however, and hold it up to the lines, you will find that they are perfectly straight and parallel.

Presidents’ Day Optical Illusion

Animation, Upside Down 16 February 2015 No Comments Yet - Share Your Thoughts

In honor of Presidents’ Day here in the United States, today’s illusion features Barack Obama, the 44th U.S. President.  Both photographs of Obama look fairly normal when viewed upside down.  When the images are inverted, however, it is obvious that his eyes and mouth are upside down on one of photographs and normal on the other.  Why do you think that this modification is difficult to see when viewing his face upside down?

This illusion is a variation of the Thatcher Illusion (because Margaret Thatcher was the original subject used) and was discovered by Psychology Professor Peter Thompson in 1980.  Thompson concluded his original article with the following:

“Further research into this illusion might help determine whether face recognition is a serial or a parallel process, is achieved by face-specific analysers searching for distinguishing characteristics or by some perceptual gestalt.  It might even tell us something about Margaret Thatcher.”

Squaring the Circle

Video 12 February 2015 No Comments Yet - Share Your Thoughts

This interesting sculpture called Squaring the Circle was created in 2013 by Troika, the UK-based artist group consisting of Conny Freyer, Eva Rucki and Sebastien Noel.  Watch the video below shot at the Kohn Gallery in Los Angeles, California to see how these CNC bent steel tubes (measuring 54 3/4 x 54 3/4 x 30 1/2 inches) form a square when viewed from one angle and a circle when viewed from another.

The following photograph shows how the steel tubes are bent to create this illusion.

Impossible Tower by István Orosz

Impossible 9 February 2015 No Comments Yet - Share Your Thoughts

The seven people sitting on the ledges of this building seem to be very confused.  Are they looking out of the windows or into the center of the building?  It looks like a tower or a cylinder, but if you investigate the construction you will find that it is anything but.
