Since a child I was fascinated by the Viewmaster viewer that showed 3D images and have a number in my collection. Last summer I visited Brian May's stereoscopic exhibition so I thought I would give it a go.
The first few I did I used a Canon 7D on a rail with a slight movement between shots, this was fine for indoor subjects but limited to anything else. I therefore decided to buy a Qoocam EGO which takes both 3D images and videos.
To view them you do need a viewer and I suggest using an Owl viewer that can be bought cheaply (£5) from The London Stereoscopic Company.
Here are a few examples with more on my 3D page of the website.
