How To Take Stereoscopic Photographs?

Stereoscopic photography is the technique of capturing two different photos which are a little offset so that it can create a 3D image. This technique is simulated based on the stereoscopic vision wherein two images are made simultaneously using two cameras or with a stereoscopic camera. The 3D effect that the photos get is due to stereopsis. Taking stereoscopic photos is quite challenging especially when you want views of an object at various orientations, for example when taking pictures of museum pieces or jewellery. But with the help of these Stereoscopic photographs many Online Diamond jewellery retailers are displaying their wares and due to these photographs, there is an increase in the sales. Refer https://www.theguardian.com/cities/2016/feb/16/stereographic-new-york-animated-3d-images-1850s-1930s to have a checkout images of the 18th century. But how do you capture these images?. Read below to know more

Step 1: Capturing 3D pictures
A decent camera and a tripod are some of the essential tools you will need to capture images. Set your camera on a flat surface on a tripod. The main subject should be placed in the centre and shot. Then move the tripod 2.5 inches to the right or left, ensure that the object you are clicking is at the centre. Take another picture at this position. So you have captured your first 3D pictures. This technique only works for objects that are still.
To capture moving objects, you will need a few more tools. As you have two cameras, mount them on tripods and place them 2.5 inches apart, switch on both the cameras at the same time to capture images. With only one camera, a mirror splitter can be used. That can help in splitting the image and also maintain the needed distance and allows you to photograph using a single camera.

Step 2: Display and viewing of 3D images
There are many ways with which you can view these images, and a few familiar forms are mentioned below.
  • With 3D glasses: The left and the right views are superimposed on each other on the screen, and the users see this as one single view.
  • Color filter glasses: The display of the image is in two colours, one colour for each view. The lenses are used to filter the different colour images. Examples are Red\Cyan, Blue\Yellow, etc.
  • Polarised glasses: These use polarised light filters. The picture is shown with one set of filters with right and left views having opposite polarity. The glasses worn by the users will be another pair of filters. The lenses filter out opposite polarity and allow matching ones through, and hence you can see full-colour images. The drawback is that you will need two projectors like in movies.
  •  Active shutter glasses: In every frame, there is a view shift between the left and right. There is a sun between the display and the glass and hence the lend block the eye at the right time. The quality of picture these glasses produce is high, and they also cost more than the other systems.
Viewing without 3D glasses:
In Wiggle 3D, there is a fast switch between the views and hence gives a 3D effect without wearing any glasses. The Mirror split has one or two mirrors that are used to overlap the images. The parallel view is one in which both the views are kept one beside the other and for the cross-eyed one, the right view is placed on the left and vice-versa.
