This Friday (21st June) is Stereoscopy Day, the third annual global celebration of stereoscopic 3D.
Organised by Denis Pellerin and Rebecca Sharpe, co-curators of the Brian May Archive of Stereoscopy, Stereoscopy Day marks 186 years since Sir Charles Wheatstone first presented the stereoscope and his theory of binocular vision to the world.
It was more than a decade ago when I first became aware of Wheatstone’s discovery.
Studying for a Masters degree in Photographic History & Research at De Montfort University, Leicester, I was fortunate enough to attend a presentation by Brian May, Denis Pellerin and Paula Fleming about their book ‘Diableries: Stereoscopic Adventures in Hell.’

For the first time, I heard terms like ‘stereocard,’ ‘stereoscope’ and ‘view’ and learned about the fascination that 3D held for the Victorians.
As it turned out, the presentation proved both inspirational and pertinent.
A few months later, my Masters research project took shape … and a professional stereographer, Percy R. Salmon FRPS (1872-1959), was at its heart.
But there was only one problem.
However hard I tried, I could not see in 3D.
The reason lay in my ‘lazy’ right eye, diagnosed when I was 7 during a school medical.
My astigmatism has meant wearing glasses ever since.
Then one day, when I had almost given up all hope of seeing in 3D, I looked at a stereocard through a hand-held stereoscope for the umpteenth time – and the two images fused into one.
I could see the promised 3D ‘view.’

Since then, stereoscopy has transformed my life, leading to a doctorate that investigated 3D’s influence on early press photography (see ‘Writings’).
It’s also improved my eye-sight, prompting my optician to wonder how this was possible given I am getting older.
What started as a handful of stereocards is now a growing collection.
It largely features the Underwood & Underwood company (1880s-1920s); plus Excelsior Stereoscopic Tours of Burnley, Lancashire; press stereographer James Edward Ellam (1857-1920); plus early stereos by W. & D. Downey and amateurs like Edward and Eliza Charlton, all featured elsewhere on this blog.
If you haven’t tried stereoscopy before, hunt down a few cards on Ebay and purchase an ‘Owl’ viewer designed by Brian May.

You won’t regret it.
