Using 3D pictures/film is going through a renaissance thanks to the ability of smart televisions to stream content and camera manufacturers developing the means by which we can take shots and shoot film. People have often asked me how a 3D camera works, so I thought I’d share with you.
A 3D camera allows you to see two-dimensional pictures in a three-dimensional settings – it is trying to replicate what your eye is seeing. So how does it work?
With a 3D camera there are two lenses just like how you view the world with your set of eyes, not one of each like an ordinary camera. When you click the shutters on a 3D device, you are using two lenses, two images have been captured. You now have a picture in your hand that is three-dimensional, not two. You can buy 3D point and shoot cameras or a compatible lens adapter to your SLR camera.
When it comes to the 3D variety, there are a couple of extra points you need to be sure of before buying.
- It needs to have the ability to process a large number of pixels – at least 16MP for quality.
- You will need a reasonably sized LCD screen. This is because you are taking 3D shots and need to interact with the interface more to get the right shot.
- Then there is memory – you’ll need some built-in, but also the ability to expand so you’ll a microSD/Compact Flash or SD card.
- Finally, there is an optical zoom feature. This is important if you want close up shots – and with 3D cameras you want the ability to take pictures that are at a minimum 10x the size of an original image.
One final question – will you need 3D glasses to view your pics? It depends. If you want to view them via the LCD on your camera, the display might have embedded polarised glass, which means you won’t need to wear anything. For your Mac/PC, then you will need the 3D glasses.
