Camera Obscura’s Vortex Tunnel – the science behind the illusion!

Test your walking and balancing skills in our vortex tunnel. But be warned, you may be left feeling a tad dizzy!

This bizarre and exciting contraption works by tricking your mind and body into thinking and feeling like the ground beneath you is moving when in fact it is completely still and fixed in place.

So, to get a little more technical as to how your mind is tricked, we need to introduce the human senses of sight and touch. Contradictory messages from these two senses make it difficult for your brain to decide what is actually happening. Your visual receptors, your eyes, see that the outer tunnel is moving, while your touch sensors (in this case your feet) feel that the ground is completely still and you are not moving. These conflicting messages make you feel off balance and a little bit dizzy.

As sight is one of the most developed senses within the human body, the brain chooses to believe sight over touch. Therefore, even though you can feel the bridge is still, your eyes see the tunnel moving which causes your brain to automatically think you are moving.

Don’t believe us? Come and give it a try for yourself!!

Faces in Space: it’s just an illusion!

Last Friday, Edinburgh saw a spectacular and rare partial solar eclipse.  Over 90% of the sun was blocked out and, even though it was not a total eclipse, it did get rather dark and noticeably colder.  In Ancient China, an eclipse was believed to have been caused by a dragon eating the sun.  People would bang drums to scare the dragon away!

In a sense, an eclipse is just a giant illusion; it looks like the sun is disappearing, but it’s not and it will soon return.

Space is full of illusions. such as when the cosmos and other planets look like faces. Take the Face on Mars, for example….

This is called ‘pareidolia’ and is a human tendency to see faces in inanimate objects.   It stems from the fact that our brains only need a few features to identify a face, and when these are seen we perceive the face – an evolutionary hangover to help us identify our fellow species, and thus safety, in dark environments.

Mars is home to another occurrence of pareidolia, a more amusing one; the Galle, or ‘happy face’, crater:

With pop culture, social media and Internet memes becoming very popular, pareidolia can be used for other objects too, such as the heat signatures of Mimas and Tethys, two of Saturn’s moons, which bear an uncanny resemblance to Pac-man.

Of course, you do not have to go to space to see pareidolia.  At the Camera Obscura, we have many examples on display, such as copies of work by the sixteenth century artist Giuseppe Arcimboldo.

 

 

You can also find examples in your own home!

Watch the Eclipse at Camera Obscura, Friday 20th March

We are offering you the unique opportunity to watch the solar eclipse in our Camera Obscura!

We will be opening our doors extra early to give you the chance to see this rare spectacle in the Camera Obscura itself.  An immense 94% of the sun’s light is expected to be blocked by the moon in this Friday’s eclipse, which will be projected live onto our large round Camera Obscura viewing table, all through a piece of technology invented over two millennia ago. Looking directly at the sun can severely damage eyesight, so it is essential to watch the eclipse through a filter or reflection.

maxresdefault

Even though the sun will not be completely covered up by the moon, this solar eclipse is not to be missed. The next partial solar eclipse is not for another ten years, and the next total solar eclipse observable from the UK will only occur in 2090.

Andrew Johnson, Manager said: this is the first time in my lifetime that we may have the opportunity to see an almost total eclipse on our camera obscura table. This is truly the best way to view it, as it is perfectly safe, and not obscured by anything.  The last time we had a partial eclipse the experience was incredible. Given clear skies, this will be even more so.

On Friday, the eclipse is predicted to begin just after 8:30am, which is why Camera Obscura and World of Illusions will be opening from 8.30am. The peak of the solar eclipse will occur at 9:35am, lasting just under 3 minutes, and it will all end at around 10:40am.

Doors open 8:30am, entry charges apply. Eclipse glasses will be available on the day and included in the ticket price (sorry, no more advance sales of glasses). Please allow enough time to climb the 6 flights of stairs to the rooftop! Tickets are valid all day.

Mesmerising GIFs!

So, today we discovered the amazing and entrancing work of visual artist David Szakaly, aka davidope (it’s taken us a while). Below are some of our favourites….be prepared to be mesmerised:

The Mystery of the Ames Room at Camera Obscura

Did you know that you can shrink and grow at ease in our Ames Room? Here’s how!….

The first Ames Room was built in 1935 by American ophthalmologist Adelbert Ames, Jr. However, it is thought the concept of the Ames Room was inspired from the German physician Hermann Helmholtz in the 1800’s.

Here comes the spoiler alert…..the Ames Room isn’t actually cubic in shape, it’s trapezoidal! The walls and ceiling are sloped and the floors are built on an incline which creates a forced perspective. This, when viewed at the right angle, tricks your brain into thinking one person is considerably taller than the other.

It has proved so effective that it has been used to create special effects in many Hollywood movies. Ever wondered how they made the Hobbits look so small next to Gandalf? Yup, that’s right, all done using the same technique! (Sorry to spoil the Shire magic for you all!)

Want to share your photos of the Ames Room? We would love to see all the creative posing we know our visitors do!

Teeny Tiny Toddler Fest ’15: How do babies’ senses develop?

Humans are born with all five senses virtually fully developed. However, slight changes and improvements happen to these senses as a baby develops and grows and this happens at a different rate for each of the five senses.  For example, by eight months a baby will have developed an understanding of a full range of sound frequencies, but it takes until the age of two for a child to develop adult perception in terms of vision. Sensory development can refer to the improvement of the five senses but it also refers to how a child reacts to the input from these senses and how they then form an appropriate response.

So, how does this all fit in with Camera Obscura and the World of Illusions?

participantWell, believe it or not, babies can be fooled by illusions from as young as five months! In 2005 the University of Bonn decided to see at what age babies begin to decipher information on distance based on perspective. The test was simple, place two toys on a chessboard background which was drawn to look like it was receding away from the babies. The toys were placed at different heights to make it look like one toy was closer to the baby than the other.  The researchers had worked out that a baby would naturally grab the toy that was closest to them. The test was repeated several times with 20 seven month old babies and 20 five month old babies, all of whom had one eye covered; this improved the perspective of the drawing and helped the babies make a more informed choice about which toy was “closer”.  The toy that was placed lower on the drawing, and therefore looked closer, was the favourite with 19 out of the 20 seven month old babies and, even more surprisingly, with 16 out of the 20 five month olds. Until this experiment was carried out, it was believed that babies could not process information on perspective.  Researchers now believe that the ability to process this information could kick in even earlier.

So, what better place to bring your little one than to Camera Obscura and World of Illusions? We’ve been fooling adults for the last 160 years…let’s see how your toddler can handle our illusions!

The event will run from the 12th-18th of January, so make sure you don’t miss out!
